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 monohydrogen 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.
一种潜伏固化的有机硅组合物包括一种可进行水合反应的金属催化有机硅组合物,以及作为水合反应抑制剂的不饱和脂肪族 1,4-二羧酸(即马来酸或乙炔二羧酸)的有机单氢衍生物。本发明中使用的有机单氢衍生物可在低温或室温下有效抑制催化的加氢反应,同时允许在高温下发生高效的加氢反应。这些单氢衍生物在低浓度下就能有效发挥其抑制功能。潜伏固化组合物可涂在基材上,为相邻的粘合剂层提供脱模表面。
