Title: Catalyst composition for room temperature vulcanizing silicone compositions and catalyzed compositions therefrom

Abstract: Stable catalyst compositions providing faster cure time in room temperature vulcanizing organopolysiloxane compositions containing them comprise stannous salts of branched chain alkyl carboxylic acids having from 8 to 12 carbon atoms and, as a stabilizing carrier therefor, a methyl alkyl polysiloxane fluid having hydroxy aryl substituents. The catalyst compositions are uniquely adapted to provide injectable compositions curable to low density, high compressive strength syntactic foams, useful, e.g., for custom fitting footwear to the wearer.
