(A) 100 weight parts of a polydiorganosiloxane,
(B) 10 to 100 weight parts of a reinforcing filler,
(C) 0.1 to 10 weight parts of a silatrane derivative described by general formula
where each R1 is independently selected from the group consisting of hydrogen atom and alkyl groups, each R2 is independently selected from the group consisting of hydrogen atoms, alkyl groups, and alkenyloxyalkyl groups described by general formula
-R4-O-R5
where R4 is an alkylene group and R5 is an alkenyl group; at least one R2 is an alkenyloxyalkyl group; and R3 is selected from alkyl groups, alkenyl groups, C1 to C10 alkoxy groups, glycidoxyalkyl groups, oxiranylalkyl groups, acyloxyalkyl groups, and aminoalkyl groups; and
(D) an organic peroxide in an amount sufficient to cure the composition.
