Uv - curable, pre-crosslinked, epoxy-functional silicones

摘要

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.
