    摘要: Provided is a room temperature moisture-curable silicone gel composition containing: (A) diorganopolysiloxane, both terminals of which are blocked by silanol groups; (B) hydrolysable organosilicon compound represented by Formula (2) and/or a partial hydrolysate thereof

    (where R 2 is a monovalent hydrocarbon group, R 3 is an alkyl group or a cycloalkyl group, and a is 2 or 3.); (C) a curing catalyst; and (D) a heat-resistant aid containing a homogeneous mixture of (D-a), (D-b), and (D-c) (where (D-a) is organopolysiloxane having a viscosity of 10-10,000 mPa·s at 25°C, (D-b) is carboxylate of cerium, and (D-c) is a titanium compound and/or a partial hydrolytic condensate thereof). This room temperature moisture-curable silicone gel composition can be a silicone gel cured product which has a small variation rate of low-stress properties evaluated by the index such as penetration even under heat-resistant conditions exceeding 230°C and which has excellent heat-resistance.
