ABSTRACT:
A buffer coating for optical fibers is disclosed which includes a halogenated epoxy resin for flame-retardancy, and elastomer modified epoxy resin for tensile strength and flexibility, a low viscosity bisphenol resin for structural integrity, a viscosity modifier for improved process or extrusion properties, a polyol to increase the cure rate and cross-linking during curing, a slip agent or surfactant to reduce the adhesion of the buffer layer to the cladding and to further improve the flow characteristics during extrusion, and a photo-initiator. The buffer layer is flame-retardant and has a fast UV cure rate.
