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.

Abstract: An improved aqueous composition for impregnating multifilament glass strand comprises emulsified polybutadiene homopolymer, butadiene-styrene-vinylpyridine terpolymer, resorcinol-formaldehyde resin, emulsified wax, a thickening agent and a defoaming agent with the homopolymer and the terpolymer emulsified with a synthetic anionic surfactant having sulfate, sulfonate or sulfosuccinate groups.

Abstract: A curable coating composition comprising a polysiloxane resin having at least two silanol groups or groups readily hydrolyzable thereto, a non-resinous silane reactable with at least two such groups for curing the polysiloxane resin and a catalyst can be stablilized against gelation by emulsifying the polysiloxane resin with a nonionic or anionic surfactant and emulsifying the catalyst with a polycarbinolpolysiloxane substantially free of silanol groups and groups readily hydrolyzable thereto, the non-resinous silane curing agent being coemulsified together with either or both of the other components. This composition is particularly useful as a coating for glass fibers to be used in elevated temperature environments.

Abstract: A conductive coating is disclosed, the coating comprising conductive particles, at least one surfactant, a thixotropic gelling agent, and, optionally, an organosilane coupling agent and a defoamer. The coating is suitable for use as a slip coating, which coating is particularly suitable for use in the production of conductive cores employed to produce electrical cables.

Abstract: A tire cord impregnant, particularly suited for coating glass fibers, is disclosed. The impregnant comprises a butadiene half ester methacrylic acid terpolymer and a blend of emulsifiable mineral oils, silica derivatives and esters.

Abstract: A semi-conductive coating for glass fibers is disclosed, the coating comprising at least one polyacrylate emulsion, a conductive carbon black dispersion and a thixotropic gelling agent. The coating being suitable for application to glass fiber roving employed to produce electrical cables.

Abstract: A tire cord impregnant, particularly suited for coating glass fibers is disclosed. The impregnant consists essentially of a vinylpyridine latex, a polybutadiene latex, a wax emulsion and a resorcinolformaldehyde resin solution.
