Silicone sponge rubber composition.

摘要

@ This invention provides organosiloxane compositions that are stable under ambient conditions and convert to cured sponge rubber when heated.

The compositions comprise an alkenyl-substituted polyorganosiloxane, a polyorganohydrogensiloxane, a platinum-type catalyst, a platinum catalyst inhibitor and an alkaline earth metal compound exhibiting a pH of at least 10.0.
