摘要:
A silicone gel composition comprising (A) 100 parts by weight of an organopolysiloxane comprising 80 to 98 mole % of R(CH3)SiO2/2 units, 0.1 to 10.0 mole % of RSiO3/2 units, and 0.1 to 10 mole % of R(CH3)2SiO1/2 units, wherein R is methyl, phenyl, or alkenyl, and provided 0.25 to 4.0 mole % 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 ¼ consistency of 10 to 200.
