Abstract: The subject of the invention is a process for manufacturing a glass strand mat, in which a binder is deposited continuously on a wad of glass strands. The strands are distributed on a moving conveyor, and then the wad is subjected to an oven treatment and possibly to calendering. The process consists of depositing on the wad of strands a liquid binder whose viscosity during deposition is less than approximately 40 millipascal seconds, the binder being formed by an aqueous solution of polyvinyl alcohol(s).

Abstract: The present invention relates to glass fibers, especially for reinforcing organic materials and having an alumino-silicate glass composition, containing one or more alkaline earth metal compounds and with a low content of alkali metal compounds, wherein the composition further contains a combination of coloring agents formed from iron oxides, cobalt oxide and, optionally, chromium oxide, which enable the fibers to be dyed in bulk and to have more neutral tones.

Abstract: The invention relates to glass threads coated with a sizing composition comprising (A) at least one alkane polyglycidyl ether, (B) at least one coupling agent and (C) at least one adhesive film-forming agent. These threads are especially suitable for reinforcing thermoplastic polyesters, such as polybutylene terephthalate or polyethylene terephthalate.

Abstract: A sizing composition is provided that includes at least one silane satisfying the following formula:Si(R.sup.1) (R.sup.2) (R.sup.3) (R.sup.4)wherein:R.sup.1 and R.sup.2 are each, independently, an alkoxy group;R.sup.3 is an alkoxy group or a hydrocarbon radical that optionally contains one or more nitrogens;R.sup.4 is a hydrocarbon radical that optionally contains one or more nitrogens, and includes at least one unsaturated ring substituted with at least one unsaturated chain conjugated with the unsaturated ring,that is useful for coating glass strands for reinforcement of organic or inorganic materials, the glass strands coated with such sizing compositions and the reinforced composite materials prepared therefrom, having mproved corrosion resistance, particularly in alkaline media.

Abstract: An aqueous emulsion for use in forming a weight average sizing coating for treating a surface of a substrate. The emulsion comprises at least one polyolefin having a molecular weight greater than 10,000; an acid material selected from the group consisting of saturated fatty acids, unsaturated fatty acids which do not includ any hydroxyl groups and mixtures thereof; at least one base; optionally, an emulsifying agent; and a sufficient amount of water to form an aqueous phase emulsion comprising from about 10-50% of solid materials.
