1. A silicone gel composition comprising:
(A) branched organopolysiloxane in an amount of 100 parts by mass, having, on average, at least two alkenyl groups bonded to silicon atoms in a molecule, and a viscosity ranging from 10 to 10,000 mPa·s at 25° C.; (B) organohydrogenpolysiloxane in an amount so that an amount of hydrogen atoms bonded to silicon atoms is 0.7 to 1.2 per one alkenyl group bonded to silicon atom in a total amount of the composition, having at least two hydrogen atoms bonded to silicon atoms in a molecule, and a viscosity ranging from 2 to 1,000 mPa·s at 25° C.; (C) a platinum-based addition reaction catalyst in an amount so that an amount of platinum-based metal is from 0.01 to 1,000 ppm in the total amount of the composition; and, (D) a reaction product, in an amount of 0.2 to 10.0 parts by mass, of (d1) alkali metal silanolate with (d2) at least one ceric salt selected from cerium chloride and a carboxylic acid salt of cerium. |
