  • Patent number: 6579914
    Abstract: A composition for coating an optical waveguide, more specifically, an optical fiber, and optical fibers coated therewith. The coating composition is a radiation curable composition including an aliphatic epoxide, a urethane acrylate oligomer, a reactive diluent, and cationic and free-radical photoinitiators. The cationic photoinitiator acts upon the aliphatic epoxide while the free-radial photoinitiator acts upon the urethane acrylate oligomer. The resulting cured coating forms an interpenetrated polymer network. The properties of coatings in accordance with the invention including the glass transition temperature thereof, can be tailored to achieve advantageous coatings suitable for use as primary coatings and secondary coatings for an optical fiber.
