Abstract
This invention relates to silicone compositions which can be crosslinked, preferably into elastomers, by hydrosilylation of at least one PolyOrganoSiloxane -A- carrying unsaturated bonds, using at least one polyorganohydrosiloxane —B— in the presence of a carbene-based metal catalyst —C— as defined in the description and which optionally comprises at least one inhibitor -D- of the hydrosilylation reaction.
