Abstract: This disclosure relates to silicone foam compositions for forming foamed silicone elastomers, the respective foamed silicone elastomers formed therefrom and to methods of making such compositions and foamed silicone elastomers. The silicone rubber foam composition comprises the (a) one or more organosilicon compounds having an average of at least two silicon bonded alkoxy groups per molecule selected from one or more silicone resins and/or silicone resin intermediates; (b) a Lewis acid catalyst; (c) one or more surfactants; and (d) one or more organopolysiloxane polymers having an average of at least two, alternatively at least three silicon bonded hydrogen groups per molecule.

Abstract: Silicone foam compositions for forming foamed silicone elastomers are described herein, together with the respective foamed silicone elastomers formed therefrom and to methods of making such compositions and foamed silicone elastomers. The silicone rubber foam composition comprising: (a) one or more organopolysiloxane polymers having an average of at least two epoxide groups per molecule; (b) a Lewis acid catalyst, (c) one or more surfactants and optionally (d) a physical blowing agent. The foamed silicone elastomers are prepared by either mechanically foaming components (a), (b) and (c); or by introducing a physical blowing agent (d); and causing foaming by physical blowing.

Abstract: A composition includes a silyl hydride (having at least one silicon-bonded hydrogen atom per molecule) and a fluorinated triarylborane Lewis acid. In the method, the Lewis acid catalyzes reaction of siliconbonded hydrogen atoms from the silyl hydride and water, thereby forming a siloxane bond in the resulting product. The composition and method can be used to form siloxane intermediates and cured networks.
