Patent ID: 7700712

Claim:
A composition comprising: a) an addition-curable siloxane compound (A), b) a siloxane crosslinker (B), c) a catalyst (C), and d) an unsaturated silane compound (D) with at least one methylene group directly attached to the unsaturation; wherein the composition does not contain an acetylenic alcohol containing at least 6 carbon atoms; wherein the composition sets at a temperature within the range of about 15 to 45° C.; and wherein the unsaturated silane compound (D) has the following structure: R 2 R 3 C═CR 1 -A-SiR 3 wherein R can be different or equal and is H, a monovalent alkyl (C 1 -C 22 ), aryl (C 6 -C 12 ), or O—SiR 4 3 group, optionally comprising heteroatoms, with the proviso that R is not an alkoxy group or an aryloxy group, R 1 , R 2 , R 3 can be different or equal and is H, a monovalent alkyl (C 1 -C 22 ), or aryl (C 6 -C 12 ) group, optionally comprising heteroatoms, R 4 is a monovalent alkyl (C 1 -C 22 ) or aryl (C 6 -C 12 ) group, wherein two or three of the residues R 4 in O—SiR 4 3 can combine to a cyclic or polycyclic structure, A is a divalent linear, branched or cyclic hydrocarbon group (C 1 -C 12 ), optionally comprising an aromatic moiety, with at least one methylene group directly attached to the unsaturation, optionally comprising O-Atoms.
