Abstract
An injection moldable composition, comprising: A) a silicone resin (I) [RSiO][RRSiO][SiO], wherein R, R, and Rare hydrocarbyl, hydrocarbyloxy, or hydroxyl, at least one of Ror Ris alkenyl, subscripts a, b, and c are each >0 and a+b+c=1, B) 0 to 90% (w/w), based on the weight of A) and B), of a silicone resin (II) [RSiO][SiO]wherein Ris hydrocarbyl, hydrocarbyloxy, or hydroxyl, at least one of Ris alkenyl, subscripts d and e are each >0, and d+e=1, C) a siloxane polymer having formula (III), [RSiO]RRSiO]. wherein Rare hydrocarbyl or hydroxyl, at least one of Ris alkenyl, subscripts f and g are each >0, and f+g=1, D) a silicone crosslinker having at least two silicon-bonded hydrogen atoms per molecule, and E) a hydrosilylation catalyst, wherein the ratio of silicon-bonded hydrogen atoms to carbon-carbon double bonds is from 1.2 to 2.2.
