Patent ID: 8772428

Claim:
An RTV-organopolysiloxane composition comprising a silicone base B capable of curing via polycondensation reaction into a silicone elastomer and a catalytically effective amount of at least one catalyst system X, wherein the catalyst system X comprises a milled homogeneous mixture of at least one metal complex or salt A dispersed in at least one oily organopolysiloxane polymer K having a viscosity of at least 100 mPa·s, and, wherein the at least one metal complex or salt A has formula (1) below: [M(L 1 ) r1 (L 2 ) r2 (Y) x ] (1) in which: r1≧1, r2≧0 and x≧0; the symbol M is a metal selected from the group consisting of copper, silver, iron, boron, scandium, cerium, ytterbium, bismuth, molybdenum, germanium and manganese; the symbol L 1 is a ligand which is a β-dicarbonylato anion or the enolate anion of a β-dicarbonyl-containing compound and when r1≧2, the symbols L 1 are identical or different; the symbol L 2 is an anionic ligand which is different from L 1 and when r2≧2, the symbols L 2 are identical or different; and the symbol Y is a neutral ligand and when x≧2, the symbols Y are identical or different.
