Abstract:
A silicone gel composition comprising:(A) 100 parts by weight of an organopolysiloxane comprising 80 to 98 mole % of R(CH.sub.3)SiO.sub.2/2 units, 0.1 to 10.0 mole % of RSiO.sub.3/2 units, and 0.1 to 10 mole % of R(CH.sub.3).sub.2 SiO.sub.1/2 units, wherein R is methyl, phenyl, or alkenyl, provided that 0.25 to 4.0 mole % of the R groups in the organopolysiloxane are alkenyl;(B) an organopolysiloxane having an average of at least 2 silicon-bonded hydrogen atoms per molecule in an amount sufficient to provide from 0.1 to 5 silicon-bonded hydrogen atoms per alkenyl group in component (A);(C) a platinum catalyst;(D) 0.01 to 10 parts by weight of a silica powder; and(E) 0.01 to 5 parts by weight of a thixotropic agent selected from at least one epoxy compound, at least one polyhydric alcohol, and mixtures thereof; wherein the silicone gel composition has an apparent viscosity ratio of 2.0 to 10.0 and cures to form a silicone gel having a 1/4 consistency of 10 to 200.
