Abstract:
A silicone composition comprising:(A) a mixture of(i) 50 to 80 wt % of a linear trimethylsiloxy-terminated polydiorganosiloxane having a viscosity of 50 to 5000 mm.sup.2 /s at 25.degree. C. and containing at least 2 alkenyl groups having at least 4 carbon atoms, the alkenyl groups comprising 0.2 to 10.0 mole % of all organic groups bonded to silicon atoms in the polydiorganosiloxane; and(ii) 20 to 50 wt % of a linear dimethylalkenylsiloxy-terminated polydiorganosiloxane having a viscosity of 50 to 5000 mm.sup.2 /s at 25.degree. C. and containing at least 2 alkenyl groups per molecule, the alkenyl groups comprising 0.2 to 10.0 mole % of all organic groups bonded to silicon atoms in the polydiorganosiloxane;(B) 3 to 50 parts by weight per 100 parts by weight of Component (A) of a polyorganohydrogensiloxane having at least 3 silicon-bonded hydrogen atoms per molecule and having a viscosity of 1 to 1000 mm.sup.2 /s at 25.degree. C.;(C) a catalytic quantity of a platinum catalyst; and(D) an inhibitor;with the proviso that the silicone composition is solventless.
