Patent ID: 7425351

Claim:
A curable silicone resin having the empirical formula (R 3 SiO 1/2 ) a (R 2 SiO 2/2 ) b (RSiO 3/2 ) c (SiO 4/2 ) d wherein each R is a hydrocarbon or a hydrogen atom; and a=0.02 to 0.8; b=0 to 0.4; and c+d=0.2 to 0.98, where a+b+c+d=1.0, and where the resin has at least 2 mole % siloxane units of the formula R′ 3 SiO 1/2 , RR′ 2 SiO 1/2 or R′ 2 SiO 2/2 , wherein each R′ is an alkenyl group.
