Patent ID: 7923507

Claim:
An elastomeric film formed from a polyorganosiloxane-containing composition which comprises: A. a cationic emulsion of a polyorganosiloxane and B. a surface-modified colloidal silica component having a zeta potential greater than zero, wherein the composition forms an elastomeric film upon the removal of water from the composition and wherein the polyorganosiloxane is comprised of the following monomeric units: wherein each R is independently selected from a saturated or unsaturated alkyl group of 1-6 carbon atoms; a saturated or unsaturated aryl group of 6-10 carbon atoms; R 1 Q; and R 1 Q 1 T; and wherein each R 1 is independently selected from an alkylene group of 1-6 carbon atoms or an arylene group of 6-10 carbon atoms; and wherein each Q is independently selected from a functional group; and wherein each Q 1 is independently selected from a non-carbon atom; and wherein each T is independently selected from a saturated or unsaturated alkyl group of 1-6 carbon atoms or a saturated or unsaturated aryl group of 6-10 carbon atoms; and wherein the a monomeric unit comprises from about 50 to about 99.9 mole percent of the polyorganosiloxane, the b monomeric unit comprises from about 0 to about 30 mole percent of the polyorganosiloxane and the c monomeric unit comprises from about 0 to about 30 percent of the polyorganosiloxane, provided that the sum of b & c must be greater than 0.
