Abstract
An automobile surface protectant composition containing volatile silicone which when applied to a wet surface displaces water and imparts gloss and water repellency. Preferably, the composition includes a volatile silicone fluid, an amino-functional silicone fluid, and an organopolysiloxane fluid.
Claims11
A nonaqueous surface protectant composition comprising:
- a. from about 10 to about 99.9 percent by weight of a volatile silicone fluid;
- b. from about 0.1 to about 10 percent by weight of a cross-linkable silicone fluid;
- and,
- c. optionally, from about 1 to about 50 percent by weight of an organopolysiloxane fluid.
A nonaqueous automobile surface protectant composition comprising:
- a. from about 10 to about 98.9 percent by weight of a volatile silicone fluid selected from the group consisting of polydimethylcyclosiloxanes having the formula [(CH.sub.3).sub.2 SiO].sub.x wherein x has a value from 3 to 8, and mixtures thereof;
- b. from about 0.1 to about 10 percent by weight of an amino-functional silicone fluid, wherein the amino-functional silicone fluid is a polyxiloxane of the general formula ##STR5## in which R.sub.1 is an oxy radical, R.sub.2 is selected from the group consisting of alkyl, aryl, and mixtures thereof, R.sub.3 is selected from the group consisting of an alkylamine radical, an alkyldiamine radical, and mixtures thereof, x is from 2 to about 20, y is 1;
- and
- c. from about 1 to about 50 percent by weight of an organopolysiloxane fluid, wherein the organopolysiloxane is a polysiloxane of the general formula ##STR6## wherein R is selected from the group consisting of alkyl radicals having up to about 30 carbon atoms, aryl, and mixtures thereof, and x has a numerical value from about 40 to about 800, providing a viscosity of 50 to 10,000 cSt. at 25.degree. C.
A nonaqueous automobile surface protectant composition comprising:
- a. from about 65 to about 85 percent by weight of a volatile silicone fluid;
- b. from about 0.1 to about 5 percent by weight of an amino-functional silicone fluid;
- and,
- c. from 1 to about 30 percent by weight of an organopolysioxane fluid.
A nonaqueous automobile surface protectant composition comprising:
- a. about 79 percent by weight of a volatile silicone fluid selected from the group consisting of decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, and mixtures thereof.
- b. about 1 percent by weight of an amino-functional silicone fluid, wherein the amino-functional silicone fluid is a polysiloxane of the general formula ##STR9## in which R.sub.1 is methoxy, R.sub.2 is selected from the group consisting of methyl, phenyl, and mixtures thereof, and R.sub.3 is selected from the group consisting of alkylamine, alkyldiamine, and mixtures thereof, x is from 2 to about 20 and y is 1;
- and,
- c. about 10 percent by weight of a tri-methyl end capped polydimethylsiloxane having a viscosity of about 50 cSt. at 25.degree. C.;
- and
- d. about 10 percent by weight of a tri-methyl end capped polydimethylsioxane having a viscosity of about 350 cSt. at 25.degree. C.
A method of displacing water from a painted, rubber, or vinyl surface of an automobile to thereby impart a glossy appearance and water repellency to the surface comprising:
- a. applying a quick-leveling protectant composition to the surface, the composition comprising:
- i. from about 10 to about 98.9 percent by weight of a volatile silicone fluid;
- ii. from about 0.1 to about 10 percent by weight of an amino-functional silicone fluid;
- and,
- iii. from 1 to about 50% of an organopolysiloxane fluid;
- and
- b. rubbing the resulting film-covered surface as needed with a suitable fiber-containing material.
