ABSTRACT:
A silicone gel composition is characterized by excellent storage stability in a non-cured state and by high adhesion to a substrate and long-term stability of consistency at elevated temperatures after curing. The silicone gel composition comprises: a polyorganosiloxane (A), which consists of polyorganosiloxane (A-1) that contains R(CH3)2SiO2/2units, RsiO3/2units R(CH3)2SiO1/2units, and polydiorganosiloxane (A-2) that contains R(CH3)2SiO2/2units and R(CH3)2SiO1/2units, and R(CH3) which contains in one molecule two silicon-bonded hydrogen atoms; an addition-reaction platinum catalyst (C); an organosilicon compound (D) selected from silane of the general formula (R1O)nSiR24-nor a partially hydrolyzed condensate thereof; and an organic titanium compound (E).
