Abstract: A method of preparing a self-releasing silicone foam in which a composition containing a siloxane polymer, an organohydrogensiloxane, a platinum catalyst, a polyol, and preferably a monofunctional alcohol is foamed, cured, and then post cured at an elevated temperature. A method of reducing the cycle time of preparing a cured silicone foam in which the above composition is applied to a plastic substrate, foamed, cured, post cured at an elevated temperature and then separated from the plastic substrate.

Abstract: The presence in foamable, curable organosiloxane compositions of a hydrogenated glyceride of an ethylenically unsaturated carboxylic acid imparts sufficient thixotropy to the uncured composition to inhibit flow without adversely affecting desirable properties of the cured foam such as density and texture.

Abstract: Liquid organosilicon compounds containing at least one alkenyl radical per molecule are included as an ingredient of moisture curable organosiloxane compositions containing a liquid polydiorganosiloxane with alkoxysilalkylene terminal units and an organotitanium compound as the curing catalyst. The organosilicon compound reacts with silicon-bonded hydrogen atoms present in said composition, thereby preventing the generation of hydrogen during storage and/or curing of the composition. One source of silicon bonded hydrogen is one of the reactants used to prepare the polydiorganosiloxane.
