Abstract:
A curable organopolysiloxane composition comprising(A) compounds which have radicals having aliphatic carbon-carbon multiple bonds,(B) organopolysiloxanes having Si-bonded hydrogen atoms, and/or,(C) organopolysiloxanes which have SiC-bonded radicals having aliphatic carbon-carbon multiple bonds and Si-bonded hydrogen atoms, wherein said organopolysiloxane composition must contain at least one component (A) or (C) having aliphatic carbon-carbon multiple bonds and at least one organopolysiloxane (B) or (C) having Si-bonded hydrogen, and(D) a platinum catalyst selected from the class consisting of ##STR3##whereR.sup.2 is an unsubstituted or substituted diene bonded to platinum via at least one .pi. bond, having an unbranched or branched chain of from 4 to 12 carbon atoms or a ring of from 6 to 18 carbon atoms,R.sup.3 are identical or different and are a hydrogen atom, halogen atom or a monovalent, unsubstituted or halogen- or cyano-substituted hydrocarbon radical having from 1 to 24 carbon atoms,R.sup.4 are identical or different bivalent, unsubstituted or substituted hydrocarbon radicals having from 1 to 24 carbon atoms,R.sup.5 are identical or different bivalent, unsubstituted or substituted hydrocarbon radicals having from 1 to 12 carbon atoms, silane radicals or siloxane radicals,R.sup.6 are identical or different and are a hydrogen atom or a monovalent hydrocarbon radical having from 1 to 20 carbon atoms,e is an integer greater than or equal to 1, andf is 0 or 1.
