Patent ID: 8729209

Claim:
An organopolysiloxane composition which does not contain any metal catalyst, said composition comprising, firstly, a silicone base B which does not comprise an organic polymer having polycondensation-crosslinkable silica-containing groups, comprising at least one polyorganosiloxane oil which can be crosslinked via a polycondensation reaction so as to form a silicone elastomer and, secondly, a catalytically effective amount of at least one polycondensation catalyst A which is a nonsilylated organic compound corresponding to formula (I): in which the R 1 radicals, which may be identical or different, and the R 3 radical are selected, independently of one another, from the group consisting of: an isopropyl radical, a cyclohexyl radical and a linear or branched, monovalent C 1 -C 12 alkyl radical, the R 2 radical represents a hydrogen atom, a linear or branched monovalent alkyl group, a cycloalkyl group, an alkyl group substituted with a ring, which is substituted or unsubstituted and which can comprise at least one heteroatom, an arylalkyl group, a fluoroalkyl group, an alkylamine group or an alkylguanidine group, and when the R 2 radical is not a hydrogen atom, the R 2 and R 3 radicals can be linked so as to form a 3-, 4-, 5-, 6- or 7-membered aliphatic ring optionally substituted with one or more substituents and with the additional condition that the R 1 , R 2 and R 3 radicals do not comprise a silicon atom.
