Injection moldable silicone composition

A method for injection molding a composition, the method comprising:

• injecting an injection moldable silicone composition comprising
• A) a silicone resin having an average formula (I)
• [R13SiO1/2]a[R2R3SiO2/2]b[SiO4/2]c, (I)
• wherein each R1, R2, and R3 is independently hydrocarbyl having from 1 to 10 carbon atoms, hydrocarbyloxy having from 1 to 10 carbon atoms, or hydroxyl, and at least one of R2 or R3 is alkenyl, and 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 having the average formula (II)
• [R43SiO1/2]d[SiO4/2]e, (II)
• wherein each R4 is independently hydrocarbyl having from 1 to 10 carbon atoms, hydrocarbyloxy having from 1 to 10 carbon atoms, or hydroxyl, and at least one of R4 is alkenyl, and subscripts d and e are each >0, and d+e=1,
• C) a siloxane polymer having an average formula (III)
• [R53SiO1/2]f[R6R7SiO2/2]g, (III)
• wherein each R5-7 are independently hydrocarbyl having from 1 to 10 carbon atoms or hydroxyl, and at least one of R5-7 is alkenyl, and 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,
• into a mold and subjecting the injected moldable composition to conditions sufficient to cure the injected moldable composition.
