SUMMARY OF THE INVENTION It is an aspect of the present invention to provide a novel epoxy composition which is generally volatile free. This composition is the reaction product of a epoxy resin, or combination of one or more resins combined with a hardener or a hardener system. The hardener can be an amine hardener such as an aliphatic or aromatic amine hardener, an anhydride hardener or a mercaptan hardener, etc. It is preferable that the hardener is an amine or mercaptan. An amine hardener system comprised of more than one amine hardener is most preferred. Preferably the amine hardener system is reacted with the epoxy resin at a equivalent ratio of from about 0.75 to about 1.05, and more preferably at from about 0.9 to about 1.0. The epoxy resin may include a base resin, along with an epoxy resin diluent for the reduction of the viscosity. Further, the resin may contain other additives, such as pigment, thixotrop- ic agents, defoamers, and the like. The amine hardener system comprises one or more amine hardeners which are aliphatic, cycloaliphatic and/or adducts of the same. These hardeners are used at from about 15 to about 40 percent by weight of a first amine hardener (based on the total weight of the amine hardener system) , which is an amino alkyl piperazine having from about 1 to about 4 carbon atoms in said alkyl group and an alkyl phenol having from about 1 to about 12 carbon atoms in said alkyl group; from about 45 to about 60 percent by weight of a second amine which is an amine derivative of ethylene, and from about 10 to about 25 percent by weight of a third amine which is an alkyl amino alkyl piperazine when all three hardeners are utilized. The hardener system further includes a catalyst which is preferably a dicarboxylic acid, and a plasticizer such as an aromatic alcohol. The epoxy composition in accordance with this invention has a low tack-free time, appropriate color and resistance to discoloration, appropriate viscosity, adhesion to various substrates including concrete, asphalt, polyurethane and glass beads, and desirable physical properties such as good impact strength com¬ pressive and tensile strength and good abrasion resis¬ tance. Further, the epoxy provides volatile free or substantially volatile free epoxy for use in road lane markers. The urethane composition is generally a two- part liquid system substantially free of any solvents and contains one or more polyisocyanates and one or more hydroxyl terminated intermediates. Desirably the polyisocyanate is a diisocyanate and the equivalent ratio of isocyanate groups to hydroxyl groups of the intermediate is generally from about 0.9 to about 1.5. At least some of the hydroxyl terminated intermediates have a functionality greater than two such as trifuncti- onal compounds so that upon reaction with a diiso¬ cyanate, a cured ' branched or crosslinked polyurethane composition is produced. Moisture scavengers such as latent polyamines can also be utilized along with various catalysts and pigments. Cure generally occurs at ambient temperature. The urethane provides good weathering resistance, good abrasion resistance, good flexibility, good tensile strength and low viscosity. An article is made by coating the urethane composition on the epoxy composition which generally serves as a base layer. The urethane, which is generally applied before the epoxy is fully cured and will typically bleed into, intermingle, mechanically bound, etc. with a portion of the epoxy substrate. Thus, a composite is formed from the epoxy and the urethane in which the layers are chemically fused and the layers subsequently have substantially no discrete interface but rather the composite has an intermediate section in which one or more compounds of the epoxy resin and/or hardener may join the respective polymeric units of both layers. This can generally be understood to be a form of or at least analogous to chemical bonding, to crosslinking and/or mechanically bonding between the layers. The epoxy layer generally serves as an excellent binder to the substrate as well as to optional reflective additives, i.e., glass beads, whereas the urethane layer has good abrasion resistance and good weatherability and thus can be used as a road lane marker. The combination of the epoxy and the urethane have the additional advantage that since both layers are free from volatiles, such as solvents, the final article is likewise free from volatiles. This is an advantage in the application of the laminate since it eliminates volatiles which could be hazardous to the environment or the workers who apply the laminate to the substrate surface. Further, glass beads are added after applica- tion of the urethane layer in order to provide excellent nighttime and wet night reflectivity. DETAILED DESCRIPTION OF THE INVENTION Articles in the form of a laminate or coated substrates are formed by generally adding a layer of the urethane composition to the epoxy composition. The epoxy composition has good bonding to surfaces such as industrial floors, garage decks, i.e. concrete and steel structures, storage tanks, roads including concrete and asphalt and the like, and hence generally serves as the substrate interface or base layer. The urethane compo¬ sition has good weatherability resistance as well as generally good abrasion resistance and therefore serves as a good durable top coat. EPOXY COMPOSITION An epoxy composition is provided which has a unique combination of hardeners in a hardener system which are used in a specified ratio in order to achieve the properties of this composition. This epoxy composi- tion is generally a volatile-free system. By "volatile- free system" it is meant that the composition generally contains less than 10 percent by weight of volatile, desirably less than 1 percent by weight, preferably no volatile at all, that is 0 percent, or completely free from volatile which can be released from the composition as a volatile. In the past, such volatiles have often resulted from the use of solvent. Thus, the composition is substantially, or even 100 percent non-solvent at ambient temperature and upon cure is 100 percent solids. In other words, the term "volatile-free system" can be understood to be free from organic components which have a boiling point of less than 120°F. This is also known in the art as a 100 percent solids system. This advan¬ tage results in a composition which is safer and more environmentally benign than prior art compositions. Despite this advantage, the composition has an appropri¬ ate viscosity to permit application such as by spraying. Epoxy compositions are generally formed by the mixing of two components, a part "A" comprising the epoxy resin, and a part "B" comprising the hardener system. The epoxy resin is reacted with a hardener system. In the invention, the preferred hardener is one or more amine hardeners as will be further discussed in greater detail. Such hardeners include, for example, aliphatic and aromatic amines, amine adducts, cycloaliphaticamines, mercaptans, polyamides, amido- amines, anhydrides and the like. In the present inven¬ tion, one or more epoxy resin can be used as the base resin with an optional epoxy modifier and other addi¬ tives. Examples of specific epoxy resins or polymers which can be utilized include but are not limited to polyhydric phenol polyether alcohols; glycidyl ethers of novolac resins such as epoxylated phenol-formaldehyde novolac resin; glycidyl ethers of mono-, di-, and trihydric phenols; glycidyl ethers of bisphenols such as diglycidyl ether of tetrabromobisphenol A; glycidyl ethers of polynuclear phenols; epoxy resin made from diphenolic acid; glycidyl ethers of aliphatic polyols such as chlorine-containing aliphatic diepoxy and polyepichlorohydrin; glycidyl esters such as aliphatic diacid glycidyl esters and epoxidized phenolphthalein; glycidyl epoxies containing nitrogen such as glycidyl amides and amide-containing epoxies; glycidyl deriva¬ tives of cyanuric acid; glycidyl resins from melamines; glycidyl amines such as triglycidyl ether amine or p- aminophenolandbis(2,3-epoxypropyl)met ylpropylammonium p-toluenesulfonate; glycidyl triazines; thioglycidyl resins such as epoxidized bisulfide; silicon-glycidyl resins suchas 1, -bis[(2,3-epoxypropoxy)dimethylsilyl]; and fluorine glycidyl resins. Other epoxy resins which can be used include those which are synthesized from mono-epoxies other than epihalohydrins including epoxy resins made from unsaturated monoepoxies such as poly- allyl glycidyl ether and glycidyl sorbate dimer; epoxy resins from monoepoxy alcohols; epoxy resins from monoepoxies by ester interchange; epoxy resins from glycidyaldehyde; polyglycidyl compounds containing un- saturation such as allyl-substituted diglycidyl ether of bisphenol A; epoxy-resin adducts of the above; and epoxy resins which are synthesized from olefins and chloro- acetyls such as butadiene dioxide, vinylcyclohexane dioxide, epoxidized polybutadiene, and bis(2,3-epoxy- cyclopentyl)ether. A more comprehensive list of epoxy resins can be found in Handbook of Epoxy Resins, by Henry Lee and Kris Neville, McGraw-Hill, Inc., 1967, which is hereby incorporated by reference. The various epoxy resins or polymers which are generally applicable to the present invention as the base epoxy resin have a number average molecular weight of from about 300 to about 5,000, and preferably from about 320 to about 390. The various epoxy polymers useful for the basic epoxy resin generally are di- functional, that is, they have two epoxide groups typically at the terminal portions thereof. A highly preferred base epoxy resin is di¬ glycidyl ether of bisphenol A (DGEBA) which has the following formula: H 2 C l CH-CH- ■ °- H 0-CH 2- CH L CH- wherein n is an integer from 0 to 18, desirably from 0.05 to 3, and preferably from 0.1 to 2. More particularly, the base epoxy resin useful for the present invention comprises a bisphenol A type resin, or a blend of bisphenol A resin and epichloro- hydrin having a weight per epoxide ranging from about 175 to about 200, and more preferably from about 180 to about 195. The resin has a viscosity at 77°C of from about 6,000 centipoise to about 18,000 centipoises, and more preferably from about 11,000 centipoises to about 16,000 centipoises and most preferably from about 11,000 to about 14,000 centipoises. The resin should have a color APHA of from about 0 to about 200. The epoxy resin can be used with a modifier such as for example a diluent. Broadly these diluents should have an epoxide equivalent weight range of 120- 325. In the present invention it is preferable to use an alkyl glycidyl ether as the diluent with a suitable range being from 2 to 20 carbon atoms in the alkyl por¬ tion. More preferably, the alkyl portion contains 3 to 10 carbon atoms, with butylglycidyl ether being most preferred. Alternatively, the diluent may be a diepoxide such as butyldiglycidyl ether. Other diluents which are applicable in the present invention include cresyl diglycidyl ether having a weight equivalence of from about 160 to about 210, and more preferably from about 170 to about 195. In addition, epoxide fractions of C2 to C20 are useful with two specific fractions being in the range of Cg to C j r j and in the range of C*^ to C^ could be used. In addition, 2-ethylhexylglycidyl ether could be used. When butylglycidyl ether is used, it preferably has a weight per epoxide equivalence of from about 120 to about 220, and more preferably from about 130 to about 260. In accordance with the present invention, the diluent is used in an amount sufficient to lower the viscosity of the epoxy resin to an appropriate number and will therefore of course depend upon the base resin used. A desired viscosity range for spray applications such as used in the present invention is from about 2,000 to about 15,000 centipoises at 77°F, and more particularly from about 3,000 to about 12,000 centi- poises, and most desirably from about 4,000 to 5,000. When the base resin is bisphenol A and the diluent is butylglycidyl ether, a preferred amount of the diluent is from about 5 to about 15; preferably from about 8 to about 12; and most preferably from about 6 to about 10 parts by weight per 100 parts by weight of the epoxy base resin. The amount of the diluent added will also depend upon the amount appropriate for the addition of the pigmentation. Other additives which can be used in the resin system include, for example, pigment. The pigment may be used, added in a desired amount, in a desired color such as for example 10 to 50; preferably 20 to 45 parts by weight per 100 parts by weight of the epoxy resins. For road marker applications in particular, a white pigment may be used which can include, for example, titanium dioxide, or a yellow pigment might be used which might include lead chromate. Of course, alterna¬ tively the epoxy can be clear, such as for a clear primer. Other conventional additives known to the art and to the literature can be utilized such as, for example, a thixotropic agent such as amorphous fumed silica, a defoa er, heat and light stabilizers, wetting and dispersing agents, antioxidants, and the like. A hardener system is combined with the epoxy resin in order to produce the resultant epoxy composi¬ tion. In the present invention, the hardener system utilizes one or more hardeners which could be an amine, an amidoamine, an anhydride or a mercaptan hardener. Examples of suitable mercaptans include generally mercaptan terminated polysulfides, such as LP32 and LP3 sold by Morton Thiokol, and Capcure 3800 and Capcure WR6 sold by Henkel. It is preferable that the hardener is one or more amine hardeners which is either aromatic or aliphatic. Suitable aromatic hardeners include methy- lene dianaline, diaminodiphenylsulphone, aromatic polyamine adducts based on methylenedianiline, modified aromatic adducts based on methylenedianiline and modi¬ fied methylene dianiline, and -phenylendiamine, its adducts and derivatives and polyamines, while aliphatic hardeners include alkyl and heterocyclic amines, and their adducts and derivatives. The hardener system preferably includes more than one hardener composition in a more preferred embodiment includes at least three compositions. Thus, when the system includes a two component system, the system may be 10 to 90 percent by weight of a first hardener and 10 to 90 percent by weight of a second hardener based on the total weight of both hardeners. When the system has three or more hardeners, the system has 5 to 90 percent of a first hardener, 5 to 90 percent of a second hardener, and from 5 to 90 percent of a third hardener. In an alternative embodiment, these amine hardeners are predominately, if not exclusively, aliphatic. The amine hardeners are used in an amount so that the gram equivalent ratio of the amine functionality to the epoxide functionality of the epoxy system is from about 0.75 to about 1.05, and more preferably from about 0.9 to about 1.0. In the present application, it is preferable that three amine hardeners are used in combination in the hardener system. In particular, when the epoxy is used with a white formulation, it may be preferable that these hardeners are at least substantially aliphatic amines since aromatic amines tend to discolor. In a narrow embodiment, the first hardener amine (a) is a combination of an alkylphenol and a aliphatic amine which is an amino-alkyl cyclodiaittine having the general formula wherein R is an alkyl having 1 to 20 carbon atoms, and preferably 1 to 8 carbon atoms; and R^ and B ~ , independently, form a heterocyclic alkyl each having 1 to 15 carbon atoms, and preferably 1 to 8 carbon atoms, and R 4 is hydrogen or ^NH 2 or R°NHR 7 , where R^ is alkyl C j and CJQ and preferably γ to C , and R° is alkyl γ to Ci Q and preferably C j to C3, and R' is alkyl C j to C-^Q and preferably C j to C3. An example of a preferred cyclo- amine is amino ethyl piperazine or bis-amino propyl piperazine. A commercial example of this is Ancamine ® 1644 sold by Pacific Anchor. Other examples would include imidazoles. This aliphatic amine is activated or modified, meaning that it is combined with an alkyl phenol having a 1 to 15 carbon alkyl, and preferably a 1 to 9 carbon alkyl, such as nonyl phenol. The combina¬ tion may be an amine adduct. The second amine hardener (b) is again a combination of an aliphatic amine with a phenol. The aliphatic amine could be an amine adduct. In this case the amine is a poly generic amine having the general formula where R° is (CH2) n , where n is 1 or 2 to 30 and prefera¬ bly about 2 to 12, and x is 1 to 10, preferably about 1 to 4. Preferred amines are diethylene tria ine, ethylenetetramine, diethylenepropylamine, tetraethyl- enepentaamine, and particularly preferred amines are diethylene triamine and triethylene tetramine. The phenol may include bisphenol A or bisphenol F and is preferably is bisphenol A. Again, the combination may result in an amine adduct. A commercial example of this is Versamine 912, sold by Henkel. The third amine hardener (c) is preferably an alkyl amino alkyl cyclodiamine having the general formula wherein R" is an alkyl having from about 1 to about 15 carbon atoms, preferably about 1 to about 10, most preferably nonyl; R*" is an alkyl having from about 1 to about 15; preferably from about 1 to about 8 (e.g. ethyl) and ΕL ~ --- and R^ together with the two amine func¬ tionalities form a heterocyclic alkyl where R 11 and R , independently, each have from about 1 to about 15; and • to preferably from 1 to about 4 carbon atoms, and where R *lJ is hydrogen, or R 14 H2 or R 15 NHR 16 , where R 14 is alkyl C j to C jβ , and preferably C j to C , and " is alkyl C- to C 10 , and preferably C j _ to C 3> snd R16 is alkyl C j to C 1Q , and preferably C-^ to C3. Specific examples include nonylaminoethylpiperazineandbis-aminopropylpiperazine. A commercial example is Versamine 908, sold by Henkel. The preferred amine hardeners are used in combination where, by weight, the first amine hardener (a) is from about 15 to about 40 percent; preferably from about 27 to about 37 percent; most preferably from about 29 to about 34 percent; the second amine hardener (b) is from about 45 to about 60 percent; preferably from about 46 to about 56 percent; most preferably from about 49 to about 53 percent, and the third amine hardener (c) is from about 10 to about 25 percent; preferably from about 12 to about 22 percent; most preferably from about 15 to about 20 percent, all of the foregoing percentages being by weight based on the total weight of a+b+c. The hardener system further includes other additives. The total hardener in the system is from about 5 to about 90 percent and more narrowly from about 10 to about 70 percent. The remainder to equal 100 percent being the other additives. One of these addi¬ tives is a catalyst which is generally a dicarboxylic acid and is preferably salicylic acid. This is used in an amount of from about 2 to about 10, and preferably from about 3.5 to about 5.5 per parts by weight per 100 parts by weight of amine hardener system a+b+c. In addition, a plasticizer may be used which is a high boiling alcohol such as the aromatic alcohols, including for example, benzyl alcohol which has a boiling point of 401°F. This is used in an amount of from about 5 to about 25; and preferably from about 10 to about 20, most preferably 15 to 20 parts by weight per 100 parts of amine hardener system (i.e. based on the total weight of a+b+c) . Further, a thixotropic agent may be used in an amount to achieve the desirable viscosity which is from about 3,000 to about 8,000, centipoises. This thixotropic agent is preferably fumed silica or silicon dioxide. It is added in an amount of from about 0.5 to 5 parts; preferably from about 1 to about 4 parts by weight per 100 parts amine hardener system (a+b+c) . The hardener system achieves an appropriate color depending on the application and in particular for road markers being white and yellow, a viscosity of from about 3,000 to about 20,000 centipoises, and further desirably physical properties, such as compression set and tensile elongation. It is desirable that the compressive strength is at least 5,000, and desirably from about 12,000 psi to about 14,000 psi as compressive strength as determined by ASTM D695, and the tensile strength is at least about 5,000, and more preferably at least 6000 psi as determined by ASTM D-638. URETHANE COMPOSITION The urethane composition is generally a liquid at ambient temperature, for example from about 10°C to about 40°C, and preferably from about 15°C to about 30°C. It is an important aspect of the present inven¬ tion that the urethane composition be volatile-free, that is generally contains less than 10 percent by weight of volatiles therein, such as a solvent, desir¬ ably less than 1 percent by weight, and preferably no volatiles at all. Such compositions are generally described as a 100 percent solids composition. Another definition of the 100 percent volatile-free urethane system is that the system, before reaction, does not contain any components which have a boiling point of less than 120°F, even though it may be liquid. The urethane composition is the reaction of a two-part or component system, that is generally an intermediate component and a polyisocyanate component. Whenever it is desirable to prevent yellowing of the urethane composition, all components and compounds thereof are aliphatic. Considering the intermediate component system, it can be a hydroxyl terminated lactone intermediate, and/or a hydroxyl terminated polyether, polyester, or a polyether-ester intermediate. The lactone based hydrox¬ yl terminated compound can either be difunctional, trifunctional, tetrafunctional, or combinations thereof, for example, blends of a difunctional lactone based intermediate and a trifunctional based lactone interme- diate, or the like. Hence, a lactone intermediate can have from about 2.0 to about 4.0 or preferably to about 3.0 hydroxyl groups per molecule. The hydroxyl termi¬ nated lactone intermediate is made from a lactone generally having from about 4 to about 8 carbon atoms with 6 carbons, that is caprolactone, being preferred. The lactone is typically reacted with a diol generally having from 2 to 8 carbon atoms and preferably from 2 to 6 carbon atoms to form the hydroxyl terminated lactone intermediate. Specific examples of such diols include ethylene glycol, propylene glycol, butylene glycol such as 1,4-butane diol, hexamethylene glycol, and the like with 1,4-butanediol being preferred. When either in combination with a diol, or when used by itself, a lactone triol intermediate can be generally made from a triol having from 3 to 12 carbon atoms, desirably from 5 to 8 carbon atoms, with specific examples including glycerol, trimethylol propane, and the like. A pre¬ ferred triol is 2-ethyl-2-(hydroxymethyl)1,3 propane diol, i.e., trimethylol propane. Similarly, various tetraols known to the art and to the literature can be utilized to make the lactone polyol intermediate. Inasmuch as desirably the lactone-based diol or triol intermediate is a liquid at ambient tempera¬ ture, it generally has a low molecular weight as from about 200 to about 1,000, and desirably from about 275 to about 450. Alternatively, a solid lactone intermedi- ate may be used if it is heated above its melting point, and uniformly dispersed prior to application. However, for ease of application, the lactone is preferably a liquid at ambient temperature. In lieu of the polylactone intermediate, or in combination therewith, a polyol intermediate can be utilized which can either be a polyester polyol, a polyether polyol, or a polyester-ether polyol intermedi¬ ate. These polyol intermediates are solvent-free. The polyether intermediate is generally made from oxy- alkylene compounds having from 2 to 6 carbon atoms and preferably 2 or 3 carbon atoms, i.e. specific examples include ethylene oxide, propylene oxide, butylene oxide, and the like, with ethylene oxide and propylene oxide being preferred. The ester intermediate is generally made from glycols or triols having from about 2 to about 10 and desirably from about 2 to about 6 carbon atoms, with specific examples including ethylene glycol, propylene glycol, butylene glycol, examethylene glycol, trimethanol propane, and the like, with ethylene glycol and propylene glycol being preferred. The polycar- boxylic acids such as a tri- or preferably dicarboxylic acids are utilized to form the ester intermediate is an aliphatic or cycloaliphatic generally containing from about 2 to about 12 carbon atoms or aromatic acids generally containing from about 8 to about 20 carbon atoms with specific examples including succinic acid, glutaric acid, adipic acid, pimelic acid, azelaic acid, phthalic acid, diphenolic acid, and the like, with adipic acid and succinic acid being preferred. Although a polyether polyol or a polyester polyol can be uti¬ lized, preferably a polyester-ether intermediate is utilized made from the above ester and ether forming polyol compounds and preferably a branched polyester- ether intermediate is utilized desirably having at least two hydroxyl end groups therein. Desirably, the mixed polyester-ether is multifunctional as containing from about 2.0 to about 3.0 hydroxyl groups therein and preferably is trifunctional. An example of a highly preferred mixed polyester-ether branch polyol intermedi¬ ate is Desmophen 1155 manufactured by Mobay. This intermediate has a hydroxy number of approximately 168 and an equivalent weight of 333. The equivalent weight of the polyether, the polyester, or the polyether-ester intermediate is generally from about 190 to about 500 and preferably from about 300 to about 400. The total amount of the various one or more polyol intermediates is generally from about 30 to about 75 parts by weight, desirably from about 40 to about 60 parts, and preferably from about 45 to about 55 parts by weight for every 100 parts by weight of the entire intermediate component. The lactone based intermediate is preferred and if another polyol intermediate is utilized in association therewith, the amount thereof is up to about 50 percent; preferably up to about 10 percent; and most preferably up to about 6 percent by weight based upon the total weight of the lactone and the other (e.g. polyether polyol) intermediates. The intermediate component also generally has a significant amount of one or more chain extenders which generally imparts stiffness to reacted urethane composition. Such chain extenders can be diols, triols, etc. having from about 2 to about 15 carbon atoms and preferably from about 2 to about 6 carbon atoms with specific examples including ethylene glycol, propylene glycol, butane diol, dipropylene glycol, diethylene glycol, glycerol, trimethylol propane diol, and the like, with the diols and specifically 1,4-butane diol being preferred. The amount of the chain extender is generally from about 5 to about 25 parts, and more preferably from about 10 to about 20, and most preferably from about 14 to about 16 parts by weight for every 100 parts by weight of the entire intermediate component. In addition to the polyol intermediate and the chain extender, optionally but desirably one or more water or moisture scavengers is utilized to generally provide a moisture free composition. Such moisture scavengers are generally known to the art as well as to the literature. A particular suitable moisture scaven¬ ger has been found to be a latent aliphatic polyamine which are generally the reaction of a diisocyanate with a hydroxyl terminated oxazolidine, such as wherein R a , R , R c , R , and R e , independently, are alkyl having from 1 to 6 carbon atoms, and the diisocyanate is R(NCO) 2 » wherein R is an aliphatic or an aromatic, or combinations thereof, generally having from about 2 to about 20 carbon atoms with specific examples including isophorone diisocyanate, hydrogenated diphenylmethane diisocyanate (HMDI) , hexa ethylene diisocyanate (HDI) , toluene diisocyanate, and the like, but diphenylmethane diisocyanate (MDI) is generally not utilized. A desir- able latent amine moisture scavenger is sold under the tradename HARDENER OZ by Mobay Chemical. Alternatively, anhydride water scavengers having a total of from 4 to 12 carbon atoms, and alkaline earth salts of such anhy¬ drides, such as methylhexahydrophthalic anhydride sold under the tradename Luketherm-M. Other anhydrides include acetic anhydride, propionic anhydride, butyric anhydride, valeric anhydride, hexanoic anhydrided, pivalic anhydride, and the like. Also molecular sieves which are generally crystalline aluminosilicates, crystalline aluminophosphates, etc. and are dispersed in a carrier oil, can be utilized. A specific example is Unisiv paste sold by UOP. The amount of the one or more water scavengers is generally from about 1 to about 8, and preferably from about 2 to about 6 and most preferably about 3.5 to about 4.5 parts by weight for every 100 parts by weight of the entire intermediate component. The second part of the urethane composition, that is the polyisocyanate component, i.e. R(NC0) n , wherein n is from 1 to about 4 and R can be an aliphatic polyisocyanate wherein R generally contains a total of from about 2 to about 20 carbon atoms and desirably from about 4 to about 10 carbon atoms. Aromatic polyiso¬ cyanates, that is aliphatic substituted polyisocyanates such as alkyl substituted polyisocyanates, aromatic substituted aliphatic polyisocyanates, etc. can also be utilized and R generally contains a total of from 6 to about 20 carbon atoms. The polyisocyanate is desirably a diisocyanate, although optionally up to 10 percent by weight of a tri or tetraisocyanate can be utilized. Examples of specific aliphatic diisocyanates include the various isophorone diisocyanates (IPDI) , the various hexane diisocyanates such as 1,6-hexane diisocyanate, the various mixed trimethylhexane diisocyanates, the various pentamethylene diisocyanates, and the like. Hexamethylene diisocyanate and isophorone diisocyanate are preferred. The aliphatic polyisocyanates generally have a molecular weight of from about 150 to about 600 and an equivalent weight average of from 80 to about 400. Examples of aromatic diisocyanates include para- phenylene diisocyanate, 4,4 -dibenzyl diisocyanate, dianisidene diisocyanate, meta-phenylene diisocyanate, tolylene diisocyanate, bitolylene diisocyanate, 4,4'- methylenebisphenyl isocyanate (MDI) , naphthalene diiso¬ cyanate, xylene diisocyanate, and the like with MDI being preferred. The aromatic polyisocyanates generally have a molecular weight of from about 100 to about 700 and an equivalent weight average of from 80 to 300. Although aromatic type diisocyanates generally give very good properties, they tend to "yellow" the urethane composition and, hence, in various situations where color or other optical properties are important, the aliphatic polyioscyanates are preferred. The equivalent molecular ratio of NCO to OH of all of the various hydroxyl terminated intermediate compounds and chain extenders, etc., is generally a slight excess as from about 0.9 to about 1.5, desirably from about 1.02 to about 1.15, and preferably from about 1.05 to about 1.10. Ratios outside of this range generally yield a reacted product which is too flexible or too hard. Various catalysts can be utilized such as dibutyl tin dilaurate, bismuth stearate, bismuth stan- nate, zinc octate, lead octate, cobalt naphthalates, and the like. The amount of such catalyst is generally small and can range from about 0 to about 2 parts by weight and preferably from about 0.1 to about 0.6 parts by weight for every 100 parts by weight of the hydroxyl containing intermediate component. In addition to promoting the reaction, the catalyst permit rapid cure at ambient temperature. Various conventional additives in suitable amounts can be utilized in the intermediate component. Such additives include fillers such as clays, silicas, and the like, various antioxidants, various ultraviolet light inhibitors, air release agents, leveling agents, wetting agents, and the like, as well as pigments. With regard to road lane markers, the pigments utilized are generally titanium dioxide for white, and lead chromate and various organic pigtents for yellow. Of course other pigments can be utilized. Article or Laminate The epoxy composition and the urethane compo¬ sition of the present invention, as noted above, are generally utilized as a laminate or layer system to form an article having good binding strength to the substrate and yet good abrasion resistance and weatherability resistance which is supplied by the urethane composi¬ tion. The articles or laminates of the present inven- tion can be utilized as protective coatings for concrete floors, steel structures, storage tanks, including tanks containing corrosive material, road lane markers, and the like. These structures can be formed of various substrate materials including, for example, steel concrete and asphalt. Since the epoxy composition has good bonding strength, it is generally utilized as a base or substrate interface layer. The two-part epoxy system is applied by mixing both parts together in any conventional manner and applying the same to the surface to be treated or coated in any conventional manner as by brushing, spraying, and the like. The thickness of the epoxy base layer will vary depending upon the surface being coated and also upon the desired degree of protection sought. With regard to a road lane marker, the thick¬ ness of the epoxy base layer which is applied is gener- ally from about 5 to about 20 mils, desirably from about 8 to about 15 mils and preferably from about 10 to about 12 mils. In actual practice, the generally liquid, two- part epoxy system can be contained on a vehicle in separate tanks, subsequently mixed under high pressure and immediately thereafter applied to an appropriate position of a road to indicate a lane marker thereon. Upon a mixing of the generally liquid solvent-free two part epoxy component system, reaction immediately commences at ambient temperature. Application to the road or other substrate can be in any conventional manner as by brushing, spraying, and the like. The two-part solvent free, generally liquid, urethane system which can be stored in separate contain¬ ers is mixed in any convention manner, and generally applied under pressure to the top of the previously applied epoxy composition. Upon mixing, the two-part urethane system will immediately commence reaction and hence it is immediately applied to the base layer before any substantial crosslinking or curing reaction occurs. Application can be in any conventional manner as by brushing, spraying, and the like. The thickness of the urethane layer will depend upon the surface being treated and the degree of protection sought and with regard to road lane marker, the urethane is generally applied at a thickness of from about 0.5 to about 10 mils, desirably from about 0.75 to about 5 mils, and preferably 2 or 3 mils. The urethane composition must be applied while the epoxy base layer is still tacky and may be cured while the epoxy system is still curing. With regard to applying a lane marker to the road, the two-part urethane composition can be applied by a second vehicle following the first vehicle. Alternatively, the urethane composition can be containe on the same vehicle which first applies the epoxy bas and shortly thereafter applies the urethane composition. When the two-part urethane composition is applied to a non-fully cured epoxy coating or base layer, there might will be some bleeding or co-mingling of the urethane composition into the epoxy composition. It is desired that the epoxy base layer is not fully cured when the urethane is applied so that a chemical bond will form between the layers. Because of the ingredients of both the epoxy system and the urethane system cure occurs at ambient temperatures. In accordance with the present invention wherein the article or laminate is utilized as a road lane marker, it is highly desirable to have nighttime reflectivity. Such reflectivity is obtained by adding transparent spheres to laminate, such as ceramic spheres and preferably glass spheres. The method of application generally involves simply sprinkling the spheres on the urethane layer while the same is still wet, i.e. not fully cured. Application of the spheres immediately after application of the urethane layer, e.g., from about 1 to about 10 seconds, generally results in the spheres being embedded generally from about 30 to about 70 percent of the total diameter thereof, and preferably from about 40 to about 50 percent. It is desirable that the laminate is heavily embedded with the spheres. The size of the various spheres will vary according to the application. Glass spheres are preferred and are readily available and generally contain a conventional sizing thereon as for example an amino silane. The present invention achieves good adhesion of the spheres as well as achieving good adhesion to the substrate. The particular laminate or article of the present invention when utilized as a lane marker results in excellent adhesion to the road surface and yet offers excellent weatherability and abrasion resistance and is expected to yield an article having a long term life. Moreover, the glass beads have been found to have excellent adhesion to the epoxy urethane laminate. The invention will be better understood by reference to the following examples but serve to illus¬ trate, but not to limit the scope of the present inven¬ tion.

(Composite) Example 15 An epoxy coating as described in Example 1 was cured with hardener described in Example 1 and applie at thickness of 12 mils. Immediately on top was place a polyurethane coating prepared as described in Exampl 7. The polyurethane coating was applied at a thicknes of 3-4 mils. The composite coating was cured for 3 day at room temperature and then found to give the followin properties: Abrasion resistance <10 mg (ASTM C501); adhesion to concrete: failure in concrete (ACI 503) ; weathering resistance: no change in color after 750 hours, 4 hours humidity, 50°C, 4 hours UV (ASTM-G53) . The test was stopped prior to discoloration. (Composited Example 16 Essentially prepared as Example 15, but after the polyurethane coating had been applied glass beads were also applied. After 3-day cure at room tempera¬ ture, the composite was found to show no change in color when subjected to accelerated weathering as described in Example 15. Comparative Example 17 For the purpose of comparison, a commercially available long-lived prior art sample based on an epoxy system made by Poly-Carb was tested and found to discol- or under acceleration within 72 hours1 In contrast, the invention demonstrates an improvement of well more than 10 times in the resistance to discoloration. This results in increased maintenance of optical properties. Example 18 To an industrial concrete floor was applied an epoxy coating prepared as described in Example 5 at a thickness of 5 mils. Just prior to the epoxy coating becoming tack free, a polyurethane coating prepared as described in Example 13 was applied on it at a thickness of approximately 10 mils. The flooring system was allowed to cure at 25°C for 12 hours and the floor returned to its normal use. The floor system was found to be aesthetically pleasing, self-leveled, easy to maintain with excellent abrasion, and impact properties as well as good chemical resistance. DISCUSSION OF THE RESULTS The foregoing examples illustrate the advantages of the present invention. Specifically, the present invention has no volatile organic components. The organic structure when based on aliphatic composi¬ tions rather than aromatic compositions has superior weatherability and resistance to discoloration. The intermediate isocyanate chemistry results in a urethane which is flexible and yet tough to very rigid by varying the chain length of either the intermediate or the iso¬ cyanate prepolymers or monomers. The resulting composi¬ tion has excellent physical properties for the intended use as well good chemical properties. The method of application results in a permanent chemical fusion between the layers. The epoxy layer has good wet- ability, while the urethane layer allows for a short tack free time. The short tack free time limits the amount of time that dirt can make it onto the surface, and shortens the time before cars can drive on the surface. The chemical fusion between the layers can be understood as the chemical reaction between the two layers which becomes a part of the polymeric structure having no discrete interface, but a form of crosslinking between the layers. It is possible to drive over the present composition within 5 to 10 minutes without harming the composition, whereas in contrast, in the past it has been necessary to wait a cure time of 60 to 75 minutes.
