Silicone gel composition excellent in damping property

Abstract

A silicone gel composition, comprising as essential components (A) an organopolysiloxane comprising substantially 90 to 97 mol % of R(CH.sub.3)SiO units, 0.1 to 2.5 mol % of RSiO.sub.1.5 units, and 0.1 to 4.0 mol % of CH.sub.3 R(CH.sub.2 .dbd.CH)Si.sub.0.5 units, wherein R represents a group selected from the group consisting of a methyl group, a phenyl group, and a CF.sub.3 CH.sub.2 CH.sub.2 -- group, provided that the total of the phenyl groups and the CF.sub.3 CH.sub.2 CH.sub.2 -- groups out of the R groups amounts to 0.5 to 10 mol % in all the R groups, (B) a hydrogenpolysiloxane containing at least one silicon-bonded hydrogen atom per molecule in such an amount that the number of the silicon-bonded hydrogen atoms is 0.5 to 1.5 per vinyl group bonded to silicon atoms in the component (A), and (C) a platinum catalyst. From this composition, a silicone gel excellent damping properties, rapid curability, and low-temperature properties can be obtained.
