Abstract

Abstract Glass fiber filament bundles such as cords for rubber reinforcement are impregnated and coated with a coating composition comprised of, in parts by weight on a dry solids basis: ______________________________________ 10-50 neoprene latex 50-90 styrene-butadiene vinylpyridine latex 4-20 resorcinol formaldehyde resin 2-6 resorcinol 1-3 formaldehyde up to 25 wax up to 25 natural rubber ______________________________________ Glass fiber cord, produced from strands and filaments, in accordance with the invention, provides an improved reinforcing member for elastomeric articles such as tires and particularly for radial tires. A method of coating the glass fibers and forming the cord from the individual filaments and strands is also disclosed.
