Abstract
Abstract 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
192 words
A detergent resistant composition which comprises I. from 35% to 99.5% by weight of a component of the formula HO[Si(CH 3 ) 2 O] x H, wherein x is a numerical value which will provide said component with a viscosity in the range of from 10 to 100,000 centistokes at ambient temperature, II. from 0.8% to 75% by weight of a component of the formula ##STR10## wherein R and R' are alkyl groups of from one to eight carbons, a and b have values of zero and one, y has a value of from zero to twenty, and X is hydrogen or an organotrialkoxysilyl group of the formula --L--Si(OR) 3 wherein R is as defined above and L is --C 3 H 6 -- or --CH 2 CHOHCH 2 C 3 H 6 --, and III. from 0.5% to 65% by weight of a component of the formula (RO) 3 SiZ or a component of the formula ##STR11## wherein R is an alkyl group of from one to eight carbons, x has a value of from 0 to 100, and Z is a nonhydrolyzable aliphatic group containing up to ten carbon atoms.
Claim 2
Dependent Claim
192 words
A detergent resistant composition which comprises I. from 35% to 99.5% by weight of a component of the formula HO[Si(CH 3 ) 2 O] x H, wherein x is a numerical value which will provide said component with a viscosity in the range of from 10 to 100,000 centistokes at ambient temperature, II. from 0.8% to 75% by weight of a component of the formula ##STR10## wherein R and R' are alkyl groups of from one to eight carbons, a and b have values of zero and one, y has a value of from zero to twenty, and X is hydrogen or an organotrialkoxysilyl group of the formula --L--Si(OR) 3 wherein R is as defined above and L is --C 3 H 6 -- or --CH 2 CHOHCH 2 C 3 H 6 --, and III. from 0.5% to 65% by weight of a component of the formula (RO) 3 SiZ or a component of the formula ##STR11## wherein R is an alkyl group of from one to eight carbons, x has a value of from 0 to 100, and Z is a nonhydrolyzable aliphatic group containing up to ten carbon atoms.
Claim 3
Dependent Claim
127 words
A detergent resistant composition as in claim 1 which comprises: I. from 70% to 95% by weight of a component of the formula HO[Si(CH 3 ) 2 O] x H, wherein x is a numerical value which will provide a said component with a viscosity in the range of from 50 to 1000 centistokes at ambient temperature, III. from 2% to 25% by weight of a component of the formula ##STR12## wherein R is methyl or ethyl, y has a value of from zero to three, and X is hydrogen or --C 3 H 6 --Si(OR) 3 and III. from 2% to 25% by weight of a component of the formula (RO).sub.2 Si(CH.sub.3)O[(RO)Si(CH.sub.3)O].sub.x (CH.sub.3)Si(OR).sub.2 wherein R is methyl or ethyl and x is from 5 to 20.
Claim 4
Dependent Claim
37 words
A detergent resistant composition as in claim 2 wherein component II comprises a mixture of amino-polysilanes which includes more than 20% by weight of [(CH 3 O) 3 SiC 3 H 6 NHCH 2 -- 2 .
Claim 5
Dependent Claim
31 words
A detergent resistant car polish or vinyl protectant composition which contains a minor amount of a composition according to one of claims 1 or 2 or 3 and an organic solvent.
Claim 6
Dependent Claim
81 words
A detergent resistant car polish composition according to claim 4 which is suitable for use on the painted exterior surface of an automobile and which contains from 0.5% to 10% by weight of the composition according to one of claims 1 or 2 or 3, from 0.1% to 5% by weight of an emulsifier, 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.
Claim 7
Dependent Claim
47 words
A method for imparting a detergent resistant polished finish to the painted exterior surface of an automobile which comprises applying thereto a film of a composition according to claim 5, allowing said film to dry, and subsequently rubbing the resulting film-covered surface with a suitable fiber-containing material.
