摘要： The invention concerns compositions that can be cured in the presence of water or atmospheric moisture comprising at least one polyorganosiloxane having one or a plurality of condensable group(s) or hydrolysable and condensable group(s) and at least one compound capable of catalyzing the condensation reaction of the condensable or hydrolysable and condensable groups of the polyorganosiloxane. This compound is a heterometallic complex of which the chemical formula comprises at least two different metal atoms M and M′, M being an atom chosen from the group consisting of the atoms of columns 2 and 13 of the periodic table and M′ being an atom chose from the group consisting of the atoms of column 4 of the periodic table, and at least one alkoxide or chelating ligand.
