Live Chat Software APS is located in Port Washington, New York occupying 10,000 square feet of laboratory and production areas. Our facilities are fully equipped with testing apparatus, homogenizer, centrifuge, mixer, extruder, coater, industrial filter, UV system and salt spray chamber. APS has fine-tuned a unique process of chemical grafting which allows manufacturers to permanently add or improve the performance of a material while retaining its existing characteristics. This process involves substrate activation, and the attachment and polymerization of monomers that contribute the desired properties (in this case corrosion resistance) onto the backbone of the substrate using safe, effective organic chemicals. Because a covalent bond is formed, the molecularly bonded formulation is permanent and cannot be leached, even under severe conditions. Coatings are used to improve the functional properties of a substrate for corrosion resistance, electrical conductivity, wear or abrasion resistance, etc. Conventional coatings adhere to substrates by simple mechanical forces which can be easily broken causing peeling or delamination. Such is not the case with chemical grafting since the attachment of graft coatings is accomplished by forming a covalent bond between the substrate and the monomers via the graft initiator. As a result, much thinner coatings can be obtained while providing longer life and superior adhesion of material. The chemical reaction that takes place provides subsurface penetration and chemical bonding. Coating thickness can be adjusted according to specification. Results have proven that coatings of .5 mil thickness can provide a minimum of 500 hours 1) Activation: free radical formation substrate activator MOH_________  MC* 2) Chemical Bonding of monomers: MO (CH2 — CH)n x x = functional group that changes with each monomer and determines the property 3) Formation of small polymer side chains: n = controlled chain length of monomers (same or varied) 4) The reaction is then terminated with a special formulation ingredient so that all reactive components are exhausted. Chemical Grafting on steel> Chemical Grafting on aluminum> Metals Corrosion Resistant Coating APS substrate activators have the unique capacity of removing active hydrogens from substrates and initiating the growth of polymer chains at that site. By removing these hydrogens, an electron is removed forming a free radical. This free radical site needs an electron to stabilize its state and will share the electron with the present monomers forming the chemical bond.

Conventional coatings need extensive surface preparation for adhesion and need to build up thickness for performance. Such is not the case with APS' coating formulations. Most APS coatings can be applied in one step with no or minimal surface preparation. In addition, due to the chemistry of APS' chemical grafting process, thinner coatings can be used to achieve a higher degree of property performance. Delamination will not occur due to the chemical bond formed between the coating and the substrate with some subsurface penetration occuring through the use of molecularly small and lightweight monomers. Typical coating methods can be used such as dip, spray, roll, flow coat, etc. APS coatings can be formulated to be air dried, however, in the interest of time, heat or some energy source (i.e., UV or infrared lights) can be used. Additives APS can develop additives to incorporate into the raw material/resin prior to extruding or molding. In this case, the new properties will penetrate the matrix of the material. APS chemists will adjust the formulation to conform to the processing parameters used by the manufacturer. Due to the molecular bond formed by APS' process, the new properties will not migrate and leach from the material over time, even under severe conditions. Laminates (Adhesives) APS chemists have extensive experience in bonding the same or different substrates together. Materials that are difficult to adhere to are effectively bonded with APS' process. Again, no or minimal surface chemical attachment of one substrate to the other. Consequently, substrate failure will occur before adhesion failure. In addition, if two substrates with different coefficients of thermal expansion are bonded, an APS developed adhesive's bonding action will not be affected. Such is not the case with conventional adhesives which cannot withstand the varying expansion and contraction of different substrates. Application of all APS chemical grafting formulations can applied at ambient temperatures and normal atmospheric conditions Our Specialized Services Each project is treated on an individual basis by formulating the desired coating, additive or adhesive according to specific requirements. Because of its easy adaptation to a wide variety of applications, chemical grafting has been utilized in virtually every industry including automotive, aerospace, industrial machinery, consumer products, medical, packaging, and many others. In order to obtain the chemically bonded product, new formulation are applied to the submitted substrate and tested according to the recommended procedures dictated by industry standards and manufacturer's requests. Once reproducible results are secured, the formulation is adapted to large-scale production at the manufacturer's location. To provide ongoing support, APS can manufacture the final formulation in the desired quantities and supply the manufacturer with a pre-mixed, ready to use coating, additive or adhesive. Metals are usually inclined to form cations through electron loss, [6] reacting with oxygen in the air to form oxides over various timescales (iron rusts over years, while potassium burns in seconds). Examples: 4 Na + O2 → 2 Na2O (sodium oxide) 2 Ca + O2 → 2 CaO (calcium oxide) 4 Al + 3 O2 → 2 Al2O3 (aluminium oxide). The transition metals (such as iron, copper, zinc, and nickel) are slower to oxidize because they form passivating layer of oxide that protects the interior. Others, like palladium, platinum and gold, do not react with the atmosphere at all. Some metals form a barrier layer of oxide on their surface which cannot be penetrated by further oxygen molecules and thus retain their shiny appearance and good conductivity for many decades (like aluminium, magnesium, some steels, and titanium). The oxides of metals are generally basic, as opposed to those of nonmetals, which are acidic. Blatant exceptions are largely oxides with very high oxidation states such as CrO3, Mn2O7, and OsO4, which have strictly acidic reactions. Painting, anodizing or plating metals are good ways to prevent their corrosion. However, a more reactive metal in the electrochemical series must be chosen for coating, especially when chipping of the coating is expected. Water and the two metals form an electrochemical cell, and if the coating is less reactive than the coatee, the coating actually promotes corrosion Advanced Polymer Solutions 99 Seaview Boulevard, Port Washington, NY 11050 (516) 621-5800 Email: info@advancedpolymersolutions.com Get Directions Chemical Grafting Adhesives Forming a covalent bond between two different substrates.
