ABSTRACT:
The combination of (1) a polyorganosiloxane composition curable by a platinum catalyzed hydrosilation reaction with (2) up to about 20 percent, based on the weight of (1), of a polyorganosiloxane composition comprising the mixture of a liquid hydroxyl-terminated polydiorganosiloxane and a moisture reactive organosilicon crosslinking agent, or the reaction product of said mixture, and an organotitanate catalyst yields elastomers that cure rapidly at temperatures of at least about 80 degrees C. and cohesively bond to inorganic substrates such as glass and metal. The resultant cured elastomer exhibits a durometer or less than about 20 on the Shore A durometer scale.
