Patent ID: 6881807

Claim:
A silicone gel composition comprising: (A) 100 parts by weight of a polyorganosiloxane having a viscosity from 10 to 100,000 mPa·s at 25° C., where polyorganosiloxane (A) comprises (i) 20 to 100 wt. % polyorganosiloxane that contains 80.0 to 99.8 mole % of R(CH 3 )SiO 2/2 units, 0.1 to 10.0 mole % of RSiO 3/2 units, and 0.1 to 10.0 mole % of R(CH 3 ) 2 SiO 1/2 units, where R is selected from the group consisting of monovalent hydrocarbon groups and alkenyl groups, wherein the alkenyl groups comprise 0.25 to 4.0 mole % of R, and (ii) 0 to 80 wt. % polydiorganosiloxane that contains 90.0 to 99.9 mole % of R(CH 3 )SiO 2/2 units and 0.1 to 10.0 mole % of R(CH 3 ) 2 SiO 1/2 units; (B) a polyorganosiloxane that has a viscosity of from 2 to 10,000 mPa·s at 25° C. and contains in one molecule two silicon-bonded hydrogen atoms, said polyorganosiloxane (B) being used in an amount such that a mole ratio of silicon-bonded hydrogen atoms contained in component (B) is within the range of 0.8 to 1.2 relative to amount of alkenyl groups in component (A); (C) a platinum catalyst used in such an amount that in terms of weigth units the metallic platinum constitutes 0.01 to 1000 ppm per total weight of components (A) and (B); (D) 0.05 to 20 parts by weight of an organosilicon compound selected from a group consisting of a silane of the general formula (R 1 O) n SiR 2 4-n and a partially hydrolyzed condensate thereof, where R 1 is an alkyl or an alkoxyalkyl group, R 2 is a substituted or non-substituted monovalent hydrocarbon group, and n is 3 or 4; and (E) 0.001 to 5 parts by weight of an organic titanium compound, wherein (B) is the only component that contains silicon-bonded hydrogen atom, said silicone gel composition having a cured-state 1/4 consistency within the range of 10 to 200 as specified JIS K 2220.
