ABSTRACT:
A latently-curable, organosilicone composition comprises a metal catalyzed organosilicone composition capable of undergoing hydrosilation and, as hydrosilation inhibitor, an organic monohydrogen derivative of an unsaturated aliphatic 1,4-dicarboxylic acid, i.e., maleic acid or acetylene dicarboxylic acid. The organic monohydrogen derivatives of use in this invention effectively inhibit catalyzed hydrosilation reactions at low or room temperature while allowing efficient hydrosilation reaction rates to occur at elevated temperatures. These monhydrogen derivatives perform their inhibitive function effectively at low concentration. The latently curable composition may be coated on a substrate to provide a release surface for an adjacent adhesive layer.
