Abstract

A composition is provided that restores and protects substrates to which it is applied including trim and tires on vehicles. The composition forms a high adhesion high cohesion film that protects the underlying substrate from the adverse effects of ultra violet (UV) rays, heat, rain, snow, and other environmental contaminants. A process of applying the same is also provided.

First claim

The invention claimed is:

1. A restorative and protective composition that cures to yield a shine coating comprising:
a curable silicone silane having silanol groups and selected from the group consisting of silicone MQ resins, and silicone MTQ resins, where M is (CH3)3SiO, Q is SiO4, and Tis (CH3) SiO3, with the proviso that at least one of M, Q, or T is modified to include a reactive terminal group of methoxy, ethoxy, dialkoyl, or trialkoxyl types;
an adhesion promoter; and
a carrier that is liquid at 20 degrees Celsius at atmospheric pressure in which said curable silicone silane and said adhesion promoter are dissolved, said carrier comprises a silicone oil, a hydrocarbon solvent, or combinations thereof.

2. The composition of claim 1 wherein said silicone silane is present from 5 to 80 total weight percent.

3. The composition of claim 1 wherein said silicone oil includes at least one of decamethylpentasiloxane, hexamethylcyclotrisiloxane, octamethylcyclo-tetrasiloxane, or oligiomeric forms that viscosities of from 2 to 10,000 centistokes (cSt).

4. The composition of claim 1 wherein said adhesion promoter is present from 3 to 40 total weight percent.

5. The composition of claim 1 wherein said adhesion promoter is present in an amount that increases a cure rate of said curable silicone silane.

6. The composition of claim 1 further comprising a catalyst.

7. The composition of claim 1 further comprising at least one additive of a dye, a glitter particulate, a bitterant, a light stabilizers, a defoamer, a corrosion inhibitors, or combinations thereof.

8. A process for applying a restorative and protective coating to a target substrate comprising:
applying the composition of claim 1 to the target substrate; and
allowing sufficient time for composition to cure onto the target substrate.

9. The process of claim 8 wherein applying is with a spray or a soaked wipe.

10. The process of claim 8 wherein applying is with an aerosol propellant.

11. The process of claim 8 wherein the target substrate is vehicle trim.

12. The process of claim 8 wherein the target substrate is a vehicle tire.

13. An article comprising:
a vehicle trim piece or a vehicle tire; and
a coating resulting from the cure of a composition of claim 1 adhered to a surface of said vehicle exterior trim piece or said vehicle tire.

14. The article of claim 13 wherein the vehicle trim piece is a vehicle exterior trim piece.

15. The article of claim 13 wherein the vehicle trim piece is a vehicle interior trim piece of a dashboard.

16. The composition of claim 6 wherein said cure catalyst is stored separately.

17. The composition of claim 16 wherein said cure catalyst is at least one of:
tetraalkyl titanate, tetraalkyl zirconate, dibutyltindiacetate, dibutyltindilaurate, dibutyltin dioctoate, dibutyltin dimalate, dibutyltin diacetate, stannous octoate, tin octylate, tetrabutyl titanate, dioctyltindilaurate, tetraisopropyltitanate titanium n-butoxide, zinc acetate, zinc 2-ethylhexanoate, or combinations thereof.
