Abstract
A method for mechanically foaming a silicone composition comprising (1) beating a gas a silicone composition which may be SiH olefin platinum catalyzed composition, a condensation type of two-component RTV composition or condensation type of one-component RTV composition and then holding the foamed composition for at least 60 seconds under vacuum of at least 600 millimeters of mercury so as to allow the foam to gel and cure.
