ABSTRACT:
UV-cured compositions comprising a precrosslinked epoxy-functional silicone and an onium salt photoinitiator are provided which have improved physical properties as compared to otherwise weak and brittle UV-cured compositions comprising non-precrosslinked epoxy-functional silicones and onium salt photoinitiators without adding fillers and without sacrificing fast, efficient UV cure speed. Such compositions are useful as conformal coatings, optical fiber coatings, and electrical encapsulation.
