ABSTRACT:
Disclosed herein is a foamable organopolysiloxane composition which comprises an organopolysiloxane base polymer containing a vinyl group-containing organopolysiloxane, organohydroxypolysiloxane, and organohydrogenpolysiloxane, and a specific siloxane copolymer containing an alkenyloxysilyl group. The composition readily foams and cures at room temperature to give a silicone rubber foam of high strength, which is useful as a filler and sealant for buildings.
