Abstract: A method and apparatus for applying size to an array of fibers of the type in which the array of fibers is directed past at least one nozzle adapted to spray a size onto the array of fibers, wherein the improvement comprises means, positioned immediately upstream from the nozzle, for removing the entrained gases flowing with the array of fibers and a conduit having a decreasing cross sectional area in the downstream direction positioned downstream from the nozzle.

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: An impregnating composition used in the treatment of glass fibers to provide a good bonding relationship between glass fibers and elastomeric materials in the manufacture of glass fiber reinforced elastomeric products formed of a resorcinol-aldehyde resin, a butadiene polymer, a wax and a copolymer of butadiene and vinyl pyridine.

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.
