Abstract
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: Also disclosed is the catalyst —C— and processes which involve crosslinking of silicone by dehydrogenating condensation (non-stick coating on paper).
