Detergent resistant compositions

Detergent resistant compositions made by blending (I) a hydroxy-terminated polydimethylsiloxane, (II) an amino-polysilane, and (III) an optionally partially hydrolyzed organotrialkoxysilane can be employed in such end-use applications as car polishes and vinyl protectants.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
This invention relates to detergent resistant compositions composed of 
silicones, aminosilanes, and organotrialkoxy silanes which may be 
partially hydrolyzed, and to their use in forming detergent resistant 
films, finishes, or coatings for such applications as car polishes and 
vinyl protectants. 
2. Description of the Prior Art 
Detergent resistant compositions consisting essentially of 
hydroxy-terminated polydimethylsiloxanes, amino-monosilanes, and 
organotrialkoxysilanes are disclosed in U.S. Pat. No. 3,836,371 and 
3,890,271. The prior art compositions, when they are allowed to cure in a 
thin film at ambient conditions, remain tacky and are easily smeared and 
susceptible to picking up dirt particles. U.S. Pat. No. 3,876,459 
discloses that compositions obtained by mixing hydroxy-terminated 
polydimethylsiloxanes, amino-monosilanes, and organotrialkoxysilanes which 
may be partially hydrolyzed can be used to render keratinous fibers (e.g., 
wool) shrink resistant. 
SUMMARY OF THE INVENTION 
Novel detergent resistant compositions are made by blending (I) a 
hydroxy-terminated polydimethylsiloxane, (II) an amino-polysilane, and 
(III) an organotrialkylsilane which may be partially hydrolyzed. The 
compositions can be applied to metal and vinyl surfaces from organic 
solvent solutions or water-based emulsions to form detergent resistant 
films, finishes, or coatings. In particular, the compositions can be used 
as additives in car polishes and vinyl protectants, to which they impart 
detergent resistant properties. 
DESCRIPTION OF THE PREFERRED EMBODIMENTS 
The novel detergent resistant compositions of this invention contain three 
primary components. 
Component I is a hydroxy-endcapped polydimethylsiloxane fluid (i.e. a 
silanol fluid) of the formula HO[Si(CH.sub.3).sub.2 O].sub.x H, wherein x 
has values which result in fluid viscosities ranging from 10 to 100,000 
(when x equals about 5 to about 1400), preferably from 50 to 20,000, and 
most preferably from 50 to 1000, centistokes at room temperature. Small 
amounts, i.e. up to about two percent, of various other groups, such as 
ethyl, propyl, phenyl, vinyl, 3,3,3-trifluoropropyl, and cyanoethyl, can 
be substituted for the methyls in the fluids without rendering them 
unsuitable for the present purpose. Component I can comprise a blend of 
the silanol fluids as described by the above formula. Component I 
comprises from 35% to 99.5%, and preferably from 70% to 95% by weight of 
the composition. 
Component II is an amino-polysilane of the formula 
##STR1## 
wherein R and R' are alkyl groups of from one to eight carbon atoms, 
preferably methyl, a and b have values of zero and one, preferably zero, y 
has a value of from zero to twenty, preferably from zero to three, and X 
is hydrogen or an organotrialkoxysilyl group of the formula 
--L--Si(OR).sub.3 wherein R is as defined above and L is --CH.sub.2 
CHOHCH.sub.2 C.sub.3 H.sub.6 -- or, preferably, --C.sub.3 H.sub.6 --. 
Examples of amino-polysilane suitable for use according to this invention 
are: 
##STR2## 
It is within the scope of this invention to utilize the Component II 
amino-polysilanes as blends. The Component II amino-polysilane blend may 
include a minor amount of other amino-silanes. For example, a typical 
preferred blend contains a major amount of some of the amino-polysilanes 
and a minor amount of the amino-silane (CH.sub.3 O).sub.3 SiC.sub.3 
H.sub.6 NHC.sub.2 H.sub.4 NH.sub.2. Component II provides the composition 
with from 0.8% to 75%, preferably from 2 to 25%, by weight of 
amino-polysilane as described. 
The Component II amino-polysilanes can be prepared by appropriate amine 
alkylations. For example, 
##STR3## 
Alternately, 
##STR4## 
Component III is an organotrialkoxysilane of the formula (RO).sub.3 SiZ or 
a partially hydrolyzed organotrialkoxysilane of the formula 
##STR5## 
wherein R is an alkyl group of from one to eight carbon atoms, preferably 
methyl or ethyl, x has a value of from 0 to 100, and is preferably a value 
which will provide this component with an SiO content of from 30% to 75% 
weight, and Z is a nonhydrolyzable aliphatic hydrocarbon group containing 
up to ten carbon atoms which may contain halogen or oxygen-containing 
groups. e.g. methyl, ethyl (which is preferred), chloropropyl, 
glycidoxypropyl, and gamma-methacryloxypropyl. The hydrolyzed compounds 
can be prepared, for example, by the HCl-catalyzed hydrolysis of e.g. 
methyl triethoxysilane. Blends of organotrialkoxysilanes and/or partially 
hydrolyzed organotrialkoxysilanes may be used. Component III comprises 
from 0.5% to 65%, preferably from 2% to 25%, by weight of the composition. 
The composition of this invention can be made by blending the three 
components--silanol fluid, amino-polysilane, and (partially hydrolyzed) 
organotrialkoxysilane--in any order at room or elevated temperatures, up 
to the boiling point of any component. The blending can be done neat or in 
organic solvents (e.g. mineral spirits, toluene, hexane). 
Preferably the aminosilane is blended with the (partially hydrolyzed) 
organotrialkoxysilane and then the hydroxy-terminated polydimethylsiloxane 
fluid is added to the silane blend. The three component blend can be 
applied neat, from an organic solvent, or from a water based emulsion to 
various surfaces (e.g. vinyl and metal surfaces of automobiles) or added 
to various products (car polishes, vinyl protectants). 
The weight ratio of hydroxy-terminated polydimethylsiloxane fluid to a 
silane blend is determined by the viscosity of the fluid. For a silanol 
fluid of 100 centistokes viscosity at room temperature, a useful weight 
ratio of fluid to silane blend if five to one; for a fluid of 1000 
centistokes viscosity at room temperature, a useful weight ratio is 
fifteen to one. The weight ratio of amino-polysilane to (partially 
hydrolyzed) organotrialkoxysilane can vary over a wide range but is 
typically near a ratio of one to one. 
Preferably, the three component blend is stirred or shaken at room 
temperature for one hour before its application to various surfaces or its 
addition to car polishes and vinyl protectants. However, it may be stirred 
or shaken for shorter times at higher temperatures, e.g. for 5 minutes at 
80.degree. C. The stirring or shaking interval allows for sufficient 
reaction among the components to ensure a high level of detergent 
resistance. The components can also be reacted in organic solvents; here 
elevated temperature and concentration of 10% by weight or more of 
components are preferred to ensure a fast buildup of detergent resistance. 
The compositions must be stored in the absence of moisture either neat or 
diluted with organic solvents to substantially reduce any tendency to gel. 
Organic solvents suitable for end-use applications in car polishes and 
vinyl protectants include mineral spirits, benzene, toluene, etc. Because 
of the high reactivity of the compositions of the present invention, it is 
preferred to apply or add them to surfaces or products (e.g. car polishes) 
once a high level of detergent resistance has been generated, e.g. after 
one hour of stirring or shaking at room temperature. 
Detergent resistant car polish compositions according to the present 
invention, which are suitable for used on the painted exterior surfaces of 
automobiles, generally contain, inter alia, a minor amount of an active 
detergent resistant composition as described herein and an organic solvent 
as indicated above. For example, such a car polish may contain from 0.5% 
to 10% by weight of said active composition, from 0.1% to 5% by weight of 
an emulsufier, from 10% to 40% by weight of a solvent, from 1% to 20% by 
weight of an abrasive, and from 40% to 80% by weight of water. In 
addition, the car polish may contain such optional ingredients as waxes, 
thickeners, perfumes, etc.

Example of Detergent Resistance 
In these Examples, tests were conducted according to the following 
procedures. The results are reported in Table 1. 
Detergent Resistance Test Method for Automobile Polishes 
A. SUBSTRATE 
C.S.M.A. approved test panel finished with black automotive paint, 
measuring twelve inches by twelve inches (12".times.12"). The panel should 
be used or "pre-conditioned"; not new or "virgin". 
B. CLEANING OF THE PANEL 
First, pre-clean with rubbing compound, then follow by washing with the 
detergent solution, described later, until water fully wets the sheet and 
does not bead-up on the surface. 
C. APPLICATION OF THE POLISHES 
1. The sheet is divided into two equal parts with strips of one-inch 
masking tape. 
2. Using a Gardner gloss meter (60.degree.), that has been standardized, 
take base point gloss measurements of each section of the unpolished panel 
that is to be used for evaluation of the candidate polishes. 
3. The polishes to be compared are applied in about the same 
amount--approximately 15 gms--(providing they have the same concentration) 
with a two-inch by two-inch (2".times.2") four layered swatch of 
cheesecloth. After the films were dried they are polished with a new 
two-inch by two-inch (2".times.2") cheesecloth swatch. Application ease of 
polish and ease of rubout of dried polishes are judged subjectively. 
D. AGING 
The panel is aged for at least twenty-four hours at room temperature. 
E. TEST FOR DETERGENT-RESISTANCE 
1. Before the detergent washing procedure again measure the gloss each 
polished section of the test panel for a second reference or base point. 
2. Detergent Solution 
1% Triton X-100(Rohm & Haas-10 mole ethoxylate of octylphenol) 
4% Potassium tripolyphosphate-(Available from Industrial Division, Stauffer 
Chemical Company) 
95% Water (Preferably deionized) 100% 
3. Washing Procedures 
a. Polished panels are placed into a support stand over a sink. 
b. Panels are wet down by cold water from rinse hose. Any marring of the 
panels by water is noted. 
c. A clean towel is dipped into the detergent solution and drained (except 
for the prewash step). 
d. The whole panel is washed back and forth, up and down, and back and 
forth. 
e. The panel is then rinsed with cold water until no detergent film 
remains. 
f. Cold water from a 300 ml. beaker is poured through funnels onto the 
panels. The water runoff properties are observed. This is done three 
times. 
g. The panel is then dried and a gloss measurement is done or, the next 
washing is done. 
F. DETERGENT RESISTANCE PROPERTIES 
I. Water Runoff 
1. Measured after each washing. 
2. Measured in seconds. 
3. Time from when last part of water stream from funnel hits the panel 
until time when water stream on panel totally beads up. 
4. Runoff times of 1-2 seconds were excellent; 3-4 seconds good; 5-6 fair; 
&gt;6 poor. 
II. Water Beading 
1. Observed after each washing. 
2. Recorded as yes (occurring)-no (no longer occurring). 
3. Observation of contact angle can indicate when detergent resistance of a 
polish is starting to fail. (The smaller the angle the nearer to polish 
failure). 
4. When beading no longer occurs, the polish is considered to have failed. 
5. Beading failure after 15 or more detergent washings was judged 
excellent; between 10-14, good; 5-9, fair; 0-4, poor. 
III. Gloss Measurement 
1. Five measurements are made per panel; one near each corner and one in 
the center. The average is considered the gloss of the panel. 
2. Measurements are made: 
a. Unpolished panels-Gloss of dried panels after abrasive cleaning. 
b. Polished panel-Gloss of panels after polish application and buffing. 
c. Prewash-panels are rinsed in cold water; then three, 250 ml. beakers of 
cold water are poured through the funnels onto the top-center of each 
panel. Gloss measurements are: 3 from the center of the runoff area and 3 
from the outside area. 
d. After wash 1, 5, 10, and 15. 
e. Gloss retention of 90+% was excellent; 70-90%, good; 50-70%, fair; 50%, 
poor.

EXAMPLE 20 
This example compares the tackiness of the blend of Example 15 with that of 
a detergent resistant composition containing 48.0 parts by weight of the 
500 centistoke embodiment of Component I, 1.0 parts by weight of an 
aminomonosilane of the formula (CH.sub.3 O).sub.3 SiC.sub.3 H.sub.6 
NHC.sub.2 H.sub.4 NH.sub.2, and 0.6 parts by weight of CH.sub.3 
Si(OCH.sub.3).sub.3. The latter composition is believed to be 
representative of the compositions taught by U.S. Pat. Nos. 3,836,371 and 
3,890,271. 
Aluminum panels were coated with composition of this invention (Example 15) 
and the prior art composition. The compositions were made by blending 
procedures described in Examples 1-4. A Baker's knife coater was used to 
lay down approximately 0.5 mil. coating on the aluminum panels. After the 
compositions were coated and allowed to cure for 24 hours at room 
temperature, a salt, talc, and sand mixture was applied to the coated 
aluminum panels. 
The salt, talc, and sand mixture was made by mixing 10% by weight talc, 10% 
by weight 40 Mesh limestone, 5% by weight salt, and 75% by weight water. 
30 grams of mixture was put on coated aluminum panels and spread around to 
cover panel. The mixture was allowed to dry on the panels; drying took 
from one to four hours. These mixture treated panels were hosed down with 
water for one minute at room temperature to see how easily cleaned the 
panels were. 
A cured coating of the Example 15 (Blend I) on aluminum panels was found to 
be clear, shiny, tack free coating. A cured coating of the prior art blend 
(Blend II) on aluminum panels was found to be a hazy, shiny, slightly 
tacky coating. 
Hosing down with water the talc/salt/sand treated aluminum panel coated 
with a cured coating of Blend I removed approximately 80% of the 
talc/salt/sand mixture. Hosing down with water the talc/salt/sand treated 
aluminum panel coated with a cured coating of Blend II removed 
approximately 10% of the talc/salt/sand mixture. The percent removal was 
estimated visually. It was concluded that aluminum panels containing a 
cured coating of Blend I of this invention are more easily cleaned than 
aluminum panels containing a cured coating of Blend II of the prior art.
