Abstract
A foam forming composition comprises (a) one or more polysiloxanes having not less than three alkylhydrogen siloxane units per molecule, (b) one or more polysiloxanes having not less than two silicon-bonded hydroxyl group per molecule, (c) at least one liquid organic titanium compound and (d) a catalyst. Reaction between the organic titanate (e.g. tetraisopropyltitanate) and the hydroxy functional polysiloxane rapidly increases viscosity of the mixture to restrict flow of the composition as it cures to form a foam within 240 seconds of mixing. A vinyl polysiloxane may be incorporated.
