Abstract:
An addition curable type silicone resin composition includes (a) an organopolysiloxane having an alkenyl group bonded to a silicon atom, (b) an organopolysiloxane represented by the formula, (R 1 R 2 2 SiO 1/2 ) m (R 1 R 2 SiO 2/2 ) n (R 2 2 SiO 2/2 ) p (R 1 SiO 3/2 ) q (R 2 (OR 3 )SiO 2/2 ) r (SiO 4/2 ) s , (c) an organohydrogen polysiloxane represented by R 4 a H b SiO (4-a-b)/2) , (d) a platinum group metal catalyst, and (e) a polyorganometallosiloxane containing an Si—O—Ce bond, and an Si—O—Ti bond, and contents of Ce and Ti of which are each 50 to 5,000 ppm, which cures by heating. According to this constitution, it is provided an addition curable type silicone resin composition which can provide a cured product excellent in transparency, and less change in hardness and weight loss under high temperature conditions.
