Abstract
A curable organopolysiloxane composition comprises: (A) an epoxy group-containing organopolysiloxane represented by the average composition formula:XRSiOwherein X represents at least one type of epoxy group selected from a glycidoxyalky group, an epoxycycloalkyl alkyl group, and an epoxyalkyl group; Rrepresents a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, an aralkyl group, a hydroxyl group, or an alkoxy group; provided at least two X groups are present in a molecule; and 'a' and 'b' are numbers satisfying: 0<a<1, 0<b<3, and 0.8<(a+b)<3; (B) a compound having at least two mercapto groups in a molecule; and (C) an amine compound not having a N—H bond and/or a phosphine compound not having a P—H bond. The composition has favorable curability even at a relatively low temperature, and forms a cured film having excellent bonding with regard to an object to be coated.
