Abstract

The present disclosure relates to hydrosilylation curable silicone rubber compositions having polyorganosiloxane cross-linkers containing at least two or at least three terminal silicon bonded hydrogen groups and one or more hydrosilylation cure inhibitor compounds selected from multiacrylates having at least three acrylate groups per molecule. Cured products resulting from the cure of such compositions and which may include elastomeric products are also disclosed. A hydrosilylation curable silicone composition comprises: (A) one or more polyorganosiloxanes containing at least two unsaturated groups per molecule, which unsaturated groups are selected from alkenyl and alkynyl groups and having a viscosity in a range of 1,000 to 200,000 mPa·s at 25° C.; (B) a polyorganosiloxane containing at least two terminal silicon bonded hydrogen groups; (C) at least one hydrosilylation catalyst; and (D) a hydrosilylation cure inhibitor comprising a multiacrylate compound having at least three acrylate groups per molecule.
