Gel-forming silicone composition

Claim 1

A gel-forming silicone composition comprising: (A) an organopolysiloxane containing an average of from 0.1 to 2 silicon-bonded alkenyl groups in its molecule and having a viscosity of from 50 to 100,000 cP at 25° C.; (B) an organohydrogenpolysiloxane containing an average of at least 2 silicon-bonded hydrogen atoms in its molecule, the amount of said silicon-bonded hydrogen atoms being in the range from 0.2 to 3.0 equivalents per equivalent of vinyl groups in said organopolysiloxane (A); (C) (C-1) a silane compound having the following general formula (1): ##STR15## wherein R 1 is an alkyl or aryl group, R 2 is an alkyl group or an alkoxyalkyl group, R 3 and R 4 may be the same or different from each other and are each any one of a hydrogen atom, a methyl group or an ethyl group, a is an integer from 0 to 2, and n is an integer from 0 to 2, or (C-2) a silane compound having the following general formula (2): (R.sup.5).sub.b --Si--(OR.sup.2).sub.4-b ( 2) wherein R 2 is the same as defined above, R 5 is at least one group selected from the group consisting of alkyl, aryl, halosubstituted alkyl, halosubstituted aryl groups, hydrogen atom, and groups represented by the following formula (2a): ##STR16## wherein in the formulas (2a), R is an alkylene group, and R 6 is an alkyl group or an aryl group, and b is an integer from 0 to 2, or partial hydrolyzate thereof; and (D) a platinum group metal catalyst.
