A silicone gel composition, comprising as essential componentsn (A) an organopolysiloxane comprising substantially 90 to 97 mol % of R(CH₃)SiO units, 0.1 to 2.5 mol % of RSiO 1.5 units, and 0.1 to 4.0 mol % of CH₃R(CH₂=CH)Si 0.5 units, wherein R represents a group nselected from the group consisting of a methyl group, a phenyl group, and a CF₃CH₂CH₂- group, provided that the total of the phenyl groups and the CF₃CH₂CH₂- 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. |
