Abstract
The present invention relates to a hardenable silicone composition including an irradiation-activated system for temporarily inhibiting the hydrosilylation reaction. Said system includes at least one inhibitor selected from among α-acetylenic alcohols, α-α′-acetylenic diesters, conjugated ene-yne compounds, α-acetylenic ketones, acrylonitriles, maleates, fumarates, the mixture thereof, at least one photoinitiator, and tris(trimethylsilyl)silane (TTMSS). The invention also relates to a method for preparing a silicone coating and hard elastomer materials provided comprising said silicone composition.
