Abstract

See full text

An improved silicone rubber coating composition is the subject of the invention. A method of reducing the surface tension of cured silicone rubber compositions is also contemplated. By utilizing a silicone rubber polymer dissolved in a suitable solvent at 50-70% concentration, SiO.sub.2 may be introduced into the composition. SiO.sub.2 in a quantity of 90-110% by weight of the polymer solution is utilized. Pigment may be added at 1-2% of the total formula weight if desired. The silicone is preferably at least 95% pure with an average particle size of 9 microns or less.
