A curable polysiloxane release coating composition comprising (A) an organic polysiloxane containing at least 2 ethylenically unsaturated groups; (B) an organic polymer containing at least 2 Si-H groups The limitation is that if the organic polysiloxane (A) contains only 2 ethylenically unsaturated groups, the organic polysiloxane (B) contains more than 2 Si-H groups per molecule on average. ; (C) a hydrosilylation catalyst comprising a platinum group metal or a complex or compound of a platinum group metal; (D1) a hydrosilylation inhibitor comprising a maleimide (D2) second hydrosilylation inhibitor , Which is selected from the group consisting of an acetylene compound, an ethylene-based unsaturated isocyanate, an acetylene-based unsaturated silane, and an unsaturated dicarboxylic acid diester or maleate compound, or a mixture thereof. |
