Abstract
Organosiloxane compositions that cure in the presence of ultraviolet radiation comprise a polymethylsiloxane containing a specified combination of mono-, di- and trifunctional siloxane units, an amount of a mercaptoalkyl-substituted polyorganosiloxane or an organic mercaptan in an amount sufficient to cure the composition to a soft, repairable gel and an amount of a photoinitiator sufficient to initiate curing of the composition in the presence of ultraviolet radiation. The cured compositions are particularly useful as coatings and encapsulants to protect electronic devices against the deleterious effects of materials present in the environment adjacent to said devices.
