A pressure-adherent silicone elastomer composition comprising a homogeneous mixture of a silicone pressure sensitive adhesive composition, a crosslinkable silicone elastomer composition and, optionally, a viscosity reducing agent. Specifically, the silicone pressure sensitive adhesive composition is a condensation product, having a plasticity of less than 200 mils, of a benzene-soluble resinous copolymer containing silicon-bonded hydroxyl radicals and consisting essentially of triorganosiloxy units of the formula R3SiO1/2 and tetrafunctionalsiloxy units of the formula SiO4/2 in a ratio of about 0.6 to 0.9 triorganosiloxy units for each tetrafunctionalsiloxy unit present in the copolymer and a polydiorganosiloxane having a viscosity from 100 centipoise to 50,000 centipoise at 25°C. |
