    摘要: An ≡SiH/≡SiOH silicone composition polymerizable/crosslinkable by dehydrogenating condensation in the presence of a catalyst judiciously selected to achieve at least one of the following: kinetics, concentration/efficiency ratio of the catalyst, cost, lowering of the catalyst activation temperature (room temperature), control of the release of gaseous hydrogen and the quality of the polymerized product and the crosslinked network, and finally limitation of the secondary reactions. This composition includes: —A— at least one ≡SiH POS; —B— at least one ≡SiOH POS; —C— at least one metal catalyst selected from the group of organometallic complexes including at least one of the following metals: Ir, Ru, Mn; —D— optionally at least one crosslinking inhibitor; —E— optionally at least one POS resin; and —F— optionally at least one filler. Also disclosed is the catalyst —C— and processes which involve crosslinking of silicone by dehydrogenating condensation (non-stick coating on paper).
