Abstract
A radiation surface-curable RTV silicone composition which subsequent to radiation surface curing thereof, is interiorly moisture-curable in character. Such radiation surface-curable, interiorly moisture-curable RTV silicone composition comprises: a silanol-containing silicone; a silane cross-linker for the silicone, such cross-linker having joined directly to a silicon atom thereof an ethylenically unsaturated functional group and at least two hydrolyzable functional groups; and a photoinitiator effective for radiation surface curing of the silicone composition. Also disclosed is a "liquid potting system" formulation, which is irradiated subsequent to dispensing thereof at the potting locus, so that the radiation surface-cured skin layer overlies and contains (cooperatively with the associated bounding surface(s) of the potting locus) the uncured liquid, so that the potted structure or material is encapsulated in a liquid (damping) medium.
