Abstract
Abstract A process for protecting, preserving, and renewing surfaces, especially rubber and other natural and synthetic polymers, leather, wood, painted surfaces and metal. An aqueous emulsion of an unsubstituted or substituted dimethylpolysiloxane fluid, or mixtures thereof, is used to thoroughly wet the surface to be protected. After a period of penetration, preferably about twenty four hours, the surface is rewetted and allowed to penetrate as in the first application. At least one additional application and penetration gives optimum protection.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
214 words
A process for preserving and renewing the surface of a solid consisting essentially of: selecting a preservative composition consisting essentially of an emulsion of at least one emulsifiable organopolysiloxane fluid and based on the weight of the organopolysiloxane fluid, from about 65 percent to about 660 percent by weight of water, and from about 0.5 percent to about 10 percent by weight of diethylene glycol and from about 60 percent to about 10 percent by weight of glycerin; thoroughly wetting the surface of said solid with said preservative composition; allowing said composition to penetrate said surface and dry for an initial drying period of approximately an hour; lightly rubbing said surface after said initial drying period; allowing said composition to penetrate said surface and dry for a total period of at least about 24 hours; lightly buffing said surface after said total period; thoroughly wetting the surface of said solid again with said preservative composition; allowing said composition to penetrate said surface and dry for a second initial drying period of approximately one hour; lightly rubbing said surface after said second initial drying period; allowing said composition to penetrate said surface and dry for a second total period of at least about 24 hours; and lightly buffing said surface after said second total period.

Dependent Claim

A process for preserving and renewing the surface of a solid consisting essentially of: selecting a preservative composition consisting essentially of an emulsion of at least one emulsifiable organopolysiloxane fluid and based on the weight of the organopolysiloxane fluid, from about 65 percent to about 660 percent by weight of water, and from about 0.5 percent to about 10 percent by weight of diethylene glycol and from about 60 percent to about 10 percent by weight of glycerin; thoroughly wetting the surface of said solid with said preservative composition; allowing said composition to penetrate said surface and dry for an initial drying period of approximately an hour; lightly rubbing said surface after said initial drying period; allowing said composition to penetrate said surface and dry for a total period of at least about 24 hours; lightly buffing said surface after said total period; thoroughly wetting the surface of said solid again with said preservative composition; allowing said composition to penetrate said surface and dry for a second initial drying period of approximately one hour; lightly rubbing said surface after said second initial drying period; allowing said composition to penetrate said surface and dry for a second total period of at least about 24 hours; and lightly buffing said surface after said second total period.
Claim 3
Dependent Claim
22 words
A process of claim 1 wherein said organopolysiloxane fluid is a dimethylpolysiloxane fluid having a viscosity of less than about 10,000 centistokes.
