ABSTRACT:
Silicone foams are prepared by microwave curing of a mixture of at least one polyorganosiloxane having vinyl groups attached to silicon; at least one hydride polysiloxane; a blowing agent comprising water and, preferably, at least one monohydroxyaliphatic compound, a cyclodextrin inclusion compound of a platinum group metal coordination complex (preferably with a cyclic diene) and a filler. The use of the inclusion compound as a catalyst increases the shelf life of the composition, whereupon curing and foaming occur together upon exposure to microwave radiation.
