Patent ID: 7906605

Claim:
A composition comprising: (A) a compound having at least one aliphatic unsaturation; (B) a cyclic organohydrogensilicon crosslinking compound containing at least one silicon-bonded hydrogen atom (SiH) per molecule, prepared by a platinum catalyzed coupling reaction of a methylhydrogen cyclosiloxane, with a reactant containing aliphatic unsaturation, hydroxy functionalities, or a mixture of both, wherein 5-70 percent of the SiH bonds in the cyclic organohydrogensilicon crosslinking compound are replaced or converted to functional groups by adding to the coupling reaction at least one functional compound selected from the group consisting of allylglycidyl ether, vinylcyclohexylepoxide, and compounds containing propargyloxy and hexynyloxy groups; and (B1) a linear organohydrogensilicon crosslinking compound containing at least one silicon-bonded hydrogen atom per molecule.
