Composition for coating optical communication glass fiber.

摘要

Coating compositions for optical communication glass fiber which have improved toughness and release characteristics are made from an organopolysiloxane having vinyl and 20 to 50 mole percent phenyl radical, a polysiloxane having dimethylvinylsiloxane units and Si0<Sub>2</Sub> units, an organohydrogenpolysiloxane, and a platinum catalyst.
