Patent ID: 8367790

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 consisting of a milled homogeneous dispersion of: (a) at least one metal complex or salt A of formula (1): [Zn(L 1 ) r1 (L 2 ) r2 (Y) x ] (1) in which: r1=1 or 2, r2=0 or 1 and x=0 or 1; 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 the symbol Y is a neutral ligand, and (b) at least one oily organopolysiloxane polymer having a viscosity of at least 100 mPa·s, wherein said at least one metal complex or salt A of formula (1) is in a solid form within said dispersion.
