Photocurable polyacrylate or methacrylate compounds which exhibit extremely low, neat viscosities while at the same time maintaining the high cure response of other related photocurable materials may be represented by the general formula: ##STR1## wherein R is hydrogen or methyl, R' is C.sub.1 -C.sub.8 alkyl or C.sub.3 -C.sub.8 alkyl ether alkyl and A is the residue of a diol or dicarboxylic acid, preferably, a diphenol such as Bisphenol A. The process for preparing these materials involves reacting a C.sub.1 -C.sub.8 aliphatic alcohol or C.sub.3 -C.sub.8 aliphatic ether alcohol with a diglycidyl ether or ester and esterifying the remaining hydroxyl groups with acrylic or methacrylic acid.

Polyester reinforcement fibers are treated to improve adhesion to rubber by applying a dissolved aromatic urethane coating to the fibers followed by coating the fibers with a resorcinol-formaldehyde latex and then heating the fibers sufficiently to convert the aromatic urethane to an aromatic isocyanate and applying to and curing a layer of rubber on said treated polyester fibers.

Epoxide resin aqueous dispersants are prepared by reacting n moles of an aromatic, aromatic-based or cycloaliphatic diol with n+1 moles of a diisocyanate and 2 moles of a long-chain, aliphatic, polyether glycol monoether.

Epoxide resin aqueous dispersant comprising the reaction product of

Water dispersible epoxide resin compositions are made by reacting a diglycidyl ether of a dihydric phenol with a dihydric phenol and a co-reactive urethane surfactant. The co-reactive surfactant is prepared by reacting a long chain aliphatic polyether glycol with a diisocyanate and a dihydric phenol in a molar ratio of 1/X/X wherein X has a value of 2 to 6. Aqueous dispersions of the water dispersible epoxide resin composition can be formulated into coating compositions.

Co-reactive urethane surfactants and stable aqueous epoxy dispersions

Tertiary amine terminated resinous compositions are prepared by reacting a molar excess of a polyepoxide compound with a dihydric phenol in a large excess of a monoamine which contains one tertiary amine group and one primary hydroxyl group. The resinous composition can be salted with an acid and can be dissolved or dispersed in water. The aqueous dispersions or solutions can be formulated into primer coatings for metal objects.

Cationic epoxide-amine reaction products

The present invention provides a two component resin coating system which when mixed forms a curable coating composition. The first component comprises a polyamine terminated polyepoxide adduct which has been salted with a controlled amount of acid. The salted product is dissolved in a co-solvent having a specifically defined solubility parameter polar component and water. The second component comprises a low molecular weight water insoluble polyepoxide crosslinker which is optionally dissolved in the selected co-solvent. When the two-components are blended together, the polyepoxide resin crosslinker is dispersed in the microemulsified state throughout the salted adduct solution and the resulting composition exhibits improved pot life, freeze thaw stability, and film forming properties.

Two component aqueous based coating composition

The present invention is directed to a two component industrial maintenance coating. The first component is a polyamine terminated epoxy resin which is end capped with a monoepoxide. The second component is a low molecular weight polyepoxide crosslinker. When salted with an acid, the adduct can be dissolved or dispersed in water. The polyepoxide crosslinker can then be microemulsified in the system. When coated on a substrate, the two component mixture cures at room temperature producing coatings having excellent balance of chemical and physical properties.

Two component aqueous coating composition based on an epoxy-polyamine

Polyepoxide resins are reacted in approximately equivalent ratios with primary amines to form cationic resinous compositions. The primary amine is a mixture of an aliphatic monoamine and an aliphatic diamine which contains one primary amine group and one tertiary amine group. The resinous reaction products can be salted with an acid and can be dissolved or dispersed in water. The aqueous dispersions or solutions can then be formulated into primer coatings for metal objects.
