Abstract

A silicone-based aerosol product includes a container and an aerosol silicone composition within the container. The aerosol silicone composition includes a silicone elastomer composition and a propellant.

Claims

1. A silicone-based aerosol product comprising:

a container; and

an aerosol silicone composition within the container;

wherein the aerosol silicone composition comprises a silicone elastomer composition and a propellant; and

wherein the silicone elastomer composition comprises;

a silanol functional fluid;

a siloxane fluid;

a catalyst; and

up to 20 wt % of at least one crosslinking agent selected from the group consisting of methyltris(methylethylketoxime)silane and vinyl tris(methylethylketoxime) silane.

2. The product of claim 1, wherein the silicone elastomer composition comprises:

25 wt % to 70 wt % of the silanol functional fluid;

20 wt % to 42 wt % of the siloxane fluid;

001 wt % to 1 wt % of the catalyst;

up to 45 wt % of at least one filler;

up to 20 wt % of the at least one crosslinking agent selected from the group consisting of methyltris(methylethylketoxime) silane and vinyl tris(methylethylketoximel silane; and

up to 3 wt % of an adhesion promoter.

3. The product of claim 2, wherein the at least one crosslinking agent is a mixture of methyltris(methylethylketoxime)silane and vinyl tris(methylethylketoxime)silane.

4. The product of claim 2, wherein the at least one crosslinking agent is methyltris(methylethylketoxime).

5. The product of claim 4, wherein the pigment filler is titanium dioxide.

6. The product of claim 2, wherein the at least one crosslinking agent is vinyl tris(methylethylketoxime)silane.

7. The product of claim 6, wherein the pigment filler is a black pigment filler.

8. The product of claim 1, wherein the aerosol silicone composition further comprises an inert gas.

9. The product of claim 1, wherein the propellant comprises a mixture of propane and butane.

10. The product of claim 9, wherein the mixture comprises from about 23 wt % to about 29 wt % propane and from about 72 wt % to about 76 wt % butane.

11. An aerosol silicone composition comprising:
