Abstract: An ambient cured aqueous coating composition useful for maintenance coatings for architectural structures or for a finish or refinish for automobiles and trucks. The film-forming binder comprises a neutralized half-ester product of an acrylic polymer having at least two reactive anhydride groups and an epoxy-containing, optionally silane-containing crosslinker. The composition may be used as a mulit-package system. The composition is characterized by improved environmental resistance and excellent clarity and appearance, particularly for clearcoats.

Abstract: Water-borne reaction products of (a) carboxyl-functional polymers; (b) polyepoxides; and (c) tertiary amines are blended with (d) carboxyl-functional polymers having an acid number dissimilar to that of (a). The resulting products are useful as film-forming components of coating compositions which can be spray-, flow-, dip-, roller-, or electro-coated and are especially useful for spray coating the inside of two-piece tin-plated steel cans of beverages and food. The coating compositions are useful as such or can be crosslinked with crosslinking agents such as a nitrogen resin.

Abstract: A durable antisoiling coating composition for textile filaments 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.

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: Described are polyester-urethane-epoxy adhesives produced by reacting one or more diols with two or more dicarboxylic acids to form a polyester prepolymer; chain-extending the prepolymer with an organic diisocyanate to yield a hydroxy-terminated polyester-urethane; capping the urethane partially or completely with a dicarboxylic acid or anhydride of dicarboxylic acid; and finally reacting with an epichlorohydrin/bisphenol A-type epoxy resin, forming an epoxy polyester-urethane block copolymer. The resulting product may then be crosslinked in use as an adhesive.
