  • UV-curable epoxy silicones
    Patent number: 5057358
    Abstract: UV-curable compositions are provided comprising blends of epoxy-functional silicones of various chain lengths. These compositions have improved physical properties as compared to otherwise weak and brittle UV-cured epoxy-functional silicones without adding fillers and without sacrificing fast, efficient UV cure speed. Such compositions are useful as conformal coatings, optical fiber coatings, and electrical encapsulation.
