Abstract
A polydiorganosiloxane gum base stock can be foamed and cured by exposing to a microwave source a composition which comprises 100 parts by weight of the stock, 3 to 25 parts by weight of an organohydrogensiloxane, 0.05 to 0.5 part by weight of an acetylenic alcohol inhibitor, 1 to 200 p.p.m. platinum as a platinum catalyst and from 0.25 to 30 parts by weight of a microwave sensible material. This method is particularly useful where it would be impractical or undesirable to use heat to foam and cure silicone compositions.
