Abstract: This disclosure relates to curable silicone rubber compositions suitable for use in the manufacture of cured-in-place gaskets (CIPGs), silicone elastomers resulting from the cure of such compositions and methods for making CIPGs from such compositions. The inclusion of a compound having at least two trialkoxysilyl groups, at least two dialkoxyalkylsilyl groups or a mixture of two or more trialkoxysilyl groups, and dialkoxyalkylsilyl groups per molecule selected from: (i) (R10)z (R11)3-z Si—(W)—Si (R11)3-z (R10)z; or (ii) 1,3,5-tris[3-((R10)z(R11)3-z Si)-D]-1,3,5-triazine-2,4,6(1H,3H,5H)-trione where each R11 is independently an alkoxy group having 1 to 6 carbons; each R10 is independently R11 or an alkyl group having 1 to 6 carbons, z is 0 or 1; W is a linear or branched alkylene having 1 to 12 carbons; and D is an alkylene group having from 1 to 6 carbons; provides CIPGs which show both a good adhesion to aluminium and a good compression set.
