Abstract: Sizing composition for glass fibers, method of making same, method of making sized glass fibers and sized glass fibers are provided to have improved sized glass fibers for use in thermosetting molding compounds. The improved sized glass fibers are produced with improved processability and have good handling characteristics and give improved properties to thermosetting molding compounds.The sizing composition is an aqueous sizing composition having water soluble or dispersible, liquid epoxy resin, melamine formaldehyde condensate, polyamide resin and thermoplastic plasticizing agent, and one or more silane coupling agents.The method of preparing the sizing composition involves adding the melamine formaldehyde condensate and polyamide resin before the addition of or in the presence of the epoxy resin.The sized glass fibers are in contact with dried residue of the epoxy resin, melamine formaldehyde-polyamide reaction product, thermoplastic plasticizing agent and one or more silane coupling agents.

Abstract: A silica complex composition suitable for the surface treatment of metals is disclosed, which comprises a water dispersible silica, an organic polymer soluble or dispersible in water and a di- or trialkoxy (or alkoxy-alkoxy) silane compound.

Abstract: An aqueous coating composition for formation of a coating film having high corrosion-resistance on a metal substrate which comprises (a) a film-forming polymeric material having at least one hydroxyl group and/or at least one carboxyl group, (b) a zwitter-ion compound and (c) an aminoplast resin and/or an epoxy resin with or without (d) a surface active agent having a hydrophilic functional group and at least one hydroxyl group and/or at least one carboxyl group.

Abstract: A durable antisoiling coating composition for textile filaments and articles made therefrom comprises a perfluoroalkyl ester of a citric acid urethane and fluorinated alcohols in combination with a modified epoxy resin which is the reaction product of a carboxyl-functional vinyl polymer, an epoxy resin and a tertiary amine. The composition can be applied as an aqueous dispersion, including a non-ionic textile lubricant based on poly(ethylene glycol). The dispersion can be used as a spin finish to provide durable protection to filaments, particularly nylon filaments.

Abstract: Novel compositions of matter comprising a water-dispersible reaction product of beta-diketones and epoxy material are hereby provided. The beta-diketones useful herein are those which enolize in amounts that render them sufficiently acidic and reactable with epoxy groups of the resin. The novel reaction products can be dispersed in water and they can be formulated optionally with curing agents. Ferrous metals treated with the compositions of this invention exhibit excellent corrosion-resistant properties.
