A silicone composition useful as a caulking material consists essentially of an aqueous emulsion of a hydroxyl endblocked polydiorganosiloxane, dialkyltindicarboxylate, phenyltrimethoxysilane, and inert non-siliceous filler. The composition is of a paste-type viscosity while an emulsion, then becomes a soft, putty-type material having a plasticity number of from 125 to 300 when the water is removed from the emulsion. The dried composition remains a soft, putty-like material upon aging. |
