Silicone rubber composition

A silicone rubber composition comprising

• (A) 100 weight parts organopolysiloxane containing at least 2 silicon-bonded alkenyl groups in each molecule,
• (B) SiH-fimctional diorganopolysiloxane having silicon-bonded hydrogen only at its two molecular chain terminals in an amount providing from 0.01 to 10 moles of silicon-bonded hydrogen per mole of silicon-bonded alkenyl in component (A),
• (C) organopolysiloxane that contains at least 3 silicon-bonded hydrogen atoms in each molecule in an amount providing 0.5 to 20 moles of silicon-bonded hydrogen per mole of silicon-bonded alkenyl in component (A),
• (D) 0.01 to 20 weight parts carbasilatrane derivative with the following general formula
• 6
• where R1 is alkyl or alkoxy, each R2 is independently selected from the group consisting of
• 7
• where R4 is alkylene or alkyleneoxyalkylene, R5 is monovalent hydrocarbyl, R6 is alkyl,
• R7 is alkylene, R8 is alkyl, alkenyl, or acyl, and a is 0, 1, or 2, and each R3 is independently selected from the group consisting of the hydrogen atom and alkyl, and
• (E) platinum catalyst in a quantity sufficient to effect cure of the composition.
