ABSTRACT:
Moisture curable, foamable compositions that do not slump appreciably in the uncured state when applied on a vertical surface, consist essentially of an RTV elastomeric composition, from 10 to 50 weight percent of a liquified blowing agent and at least 12 weight percent finely divided filler. The RTV elastomeric composition comprises the product obtained by mixing at least two moisture curable polydiorganosiloxanes with an effective amount of a moisture reactive crosslinker. A graft copolymer derived from a liquid polydiorganosiloxane and an ethylenically unsaturated organic monomer constitutes from 5 to 80 weight percent of the polydiorganosiloxanes.
