Abstract
A coating composition substantially prevents fraying of glass fiber yarn packages. The composition is composed of an aqueous solution of a resin formed of the hydrolysis product of a copolymer of vinyl aromatic monomer and maleic anhydride, an organo silane glass fiber anchoring agent and an effective amount of a water-soluble pyrrolidone-containing polymer sufficient to form a protective film over the glass fiber.
Claims12
A coating composition for glass fibers comprising an aqueous solution of a resin comprising a hydrolysis product of a copolymer of a vinyl aromatic monomer and maleic anhydride, an organo silane glass fiber anchoring agent in an amount of between about 0.3% to about 1.0 by weight of the coating composition, and an effective amount of a water-soluble pyrrolidone-containing polymer the pyrrolidone containing polymer being present in an amount not less than about 0.2% and not greater than about 0.4% by weight of the coating composition, the coating composition being present in an amount sufficient to form a protective film over the glass fiber.
