Abstract

A water-based composition for enhancing shine or gloss in an elastomeric surface is in the form of a stable aqueous dispersion having a pH of from about 6 to about 7 and containing by weight: (a) less than 10% of at least one polydiorganosiloxane fluid; (b) from about 0.02% to about 2.0% of an alkali-swellable acrylic homopolymer or copolymer crosslinked with a polyalkenyl polyether; and (c) water. In one embodiment, the composition contains less than 1% by weight of a wetting agent and has no additional surfactants, hydrotropes and emulsifying agents. The composition can be used to enhance shine or gloss in elastomeric surfaces such as rubber or vinyl, preferably automotive tires, by applying an effective amount of the composition to the surface and distributing the composition with an application implement. The composition contains less organopolysiloxane than commercial formulations but exhibits gloss-enhancing performance that is comparable or even higher than that exhibited by commercial compositions.

Claims (26)

1. A sprayable water-based composition for enhancing shine or gloss in an elastomeric surface, the composition being in the form of an aqueous dispersion comprising:

(a) from about 0.1% to about 20% by weight of at least one polydiorganosiloxane fluid;

(b) from about 0.02 to about 2.0% by weight of an alkali-swellable acrylic homopolymer crosslinked with a polyalkenyl polyether or an alkali-swellable acrylic copolymer crosslinked with a polyalkenyl polyether;

(c) from about 85% to about 98% by weight of water;

(d) one or more solvents wherein the composition only contains solvents which have a refractive index of about 1.4 to about 1.5; and

(e) from about 0.10 to about 1.0% of a silicone wetting agent for reducing surface tension when dissolved in water or a water solution.

2. A composition according to claim 1 , wherein the alkali-swellable acrylic polymer or copolymer is present at a level of from about 0.05% to about 0.10% by weight of the composition.

3. A composition according to claim 1 , wherein the at least one polydiorganosiloxane fluid is selected from the group consisting of silicone oils having the general formula:

(R n SiO ((4-n)/2) ) m

wherein n is between 0 and 3, m is 2 or greater, and R is selected from the group consisting of alkyl, alkylene, allyl, aryl, benzyl, phenyl, amine, amide, vinyl, fluoroalkyl, perfluoroalkane, carboxyester and quaternary alkyl ammonium radicals, and mixtures thereof.

4. A composition according to claim 3 , wherein the polydiorganosiloxane fluid is selected from the group consisting of polydimethylsiloxane, polydiethylsiloxane, polymethylphenylsiloxane, polyalkylarylsiloxane, polyethylene-oxydialkylsiloxane, polypropylene-oxydialkylsiloxane, polydialkylcyclosiloxane and mixtures thereof.

5. A composition according to claim 1 , wherein the polydiorganosiloxane fluid is a polydimethylsiloxane fluid having a viscosity of from about 2 to about 60,000 centistokes at 25° C.

6. A composition according to claim 1 , wherein the wetting agent comprises a silicone polyether.

7. A composition according to claim 1 , wherein the composition further comprises one or more buffers or pH adjusting agents.

8. A composition according to claim 1 , wherein the solvent is selected from the group consisting of: glycerin, sorbitol, and combinations or mixtures thereof.

9. A method of enhancing shine or gloss in an elastomeric surface, comprising:

(1) applying an effective amount of the composition of claim 1 to said surface; and

(2) distributing said composition onto said surface with a sprayer.

10. A method according to claim 9 , wherein the polydiorganosiloxane fluid comprises a polydimethylsiloxane fluid having a viscosity of from about 300 to about 400 centistokes at 25° C.

11. A method according to claim 9 , wherein the water-based composition is self-leveling and does not require any touching or wiping to spread the composition over the surface evenly.

12. A method according to claim 9 , wherein the elastomeric surface comprises rubber or vinyl.

13. A composition according to claim 1 , wherein the composition exhibits a rheological Critical Strain value greater than zero and less than about 0.5 and an Elastic Modulus value greater than zero and less than about 400 Pascals.

14. A composition according to claim 1 , wherein the elastomeric surface comprises a vinyl, leather, rubber or synthetic plastic surface.

15. A composition according to claim 1 , wherein the elastomeric surface comprises an automotive surface selected from vinyl interior surfaces, leather interior surfaces and exterior rubber surfaces.

16. A composition according to claim 1 which has no emulsifying agent apart from the silicone wetting agent.

17. A composition according to claim 16 wherein the emulsifying agent is a surfactant apart from the silicone wetting agent.
