Abstract
Provided is a silicone gel composition that provides a silicone gel cured product having excellent storage stability as well as heat resistance and transparency at high temperatures, being capable of maintaining low elastic modulus, low stress, and high transparency even when used for long periods of time, particularly under conditions where only one direction of a member is exposed to high temperatures, and having resistance to cracking, peeling, and the like. The silicone gel composition comprises (A) a branched organopolysiloxane having an alkenyl group bonded to a silicon atom, (B-1) a branched organohydrogenpolysiloxane having three or more silicon atom-bonded hydrogen atoms in a molecule, and containing at least 20 mol % or more of T units and Q units of all siloxane units, (B-2) a chain organohydrogenpolysiloxane having two silicon atom-bonded hydrogen atoms in one molecule, (C) a platinum-based addition reaction catalyst, and (D) a reaction product of ceric salt.
