ABSTRACT:
Radiation-curable compositions consisting essentially of a triorganosiloxane-endblocked polydiorganosiloxane fluid bearing a small percentage of mercaptoalkyl radicals and a curing agent comprising a 1,1'-oxy-bis-(1-methyl-1-silacyclopentene) are disclosed. When applied to a substrate and exposed to energetic radiation these compositions rapidly cured to provide a coating on the substrate that releases aggressive adhesives. Advantageously, the coating, when cured with ultraviolet light in air, is essentially free of the obnoxious odor which characterizes the analogous compositions of the art which are cured with only polymethylvinylsiloxane as a curing agent.
