  • Radiation curable matrix composition
    Publication number: 20080085947
    Abstract: Radiation curable compositions suitable for use a optical fiber ribbon matrix materials are provided which have at least two non-silicone urethane(meth)acrylate oligomers, one or more multifunctional diluents and one or more photoinitiators, wherein each of the non-silicone urethane(meth)acrylate oligomers has a number average molecular weight of about 200 or more, but less than about 6000, and the polydispersity index (PDI) of the urethane(meth)acrylate oligomers is from 2:1 to 30:1. The matrix material may be coated and cured on a plurality of optical fibers so as to form an optical fiber ribbon assembly.
