The invention relates to a crosslinkable composition X, comprising: at least one organopolysiloxane compound A comprising, per molecule, at least two C2-C6 alkenyl radicals bonded to silicon atoms; at least one organohydrogenopolysiloxane compound B comprising, per molecule, at least two hydrogen atoms bonded to an identical or different silicon atom; at least one catalyst C which is a complex corresponding to the following formula: [Co (L1)2] in which: the symbol Co represents cobalt at degree of oxidation II; the symbols L1, which may be identical or different, represent a ligand which is a -dicarbonylato anion or the enolate anion of a -dicarbonylated compound; optionally at least one adhesion promoter D; and optionally at least one charge E. The invention also relates to the use of the previously described catalyst C as silicone composition crosslinking catalyst, to a silicone composition crosslinking method, characterized in that it consists in heating the composition X to a temperature of between 70 and 200C, and to the resulting crosslinked silicone material Y.

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.

A method of lubricating an expandable rubber bladder is described for use during a vulcanization of a green tire within a metal press. The method can include applying compositions in the form of emulsions of silicone oils to the inner surface of the green tires and/or to the outer surface of the vulcanization bladders to facilitate the molding-demolding thereof during the manufacture of the tires.


The invention relates to a silicone composition comprising components bearing SiH/SiOH groups, which can be polymerised/cross-linked by means of a dehydrogenative condensation reaction in the presence of a carbene-type catalyst in solution.


The present invention concerns novel polyorganosiloxane compositions that can be hot-vulcanised into silicone elastomers, i.e. that can be vulcanised at temperatures generally in the region of between 100 and 200 C. and, if necessary, up to 250 C. The invention also concerns the use of these compositions for the production of casings or primary insulators used to form electrical wires or cables protected against fire. The invention finally concerns the electrical wires or cables protected against fire that are produced using said compositions.
