Abstract: Package and tank stable low temperature self-curing cation-active aqueous soluble or dispersible coating compositions are prepared by polymerizing blocked isocyanatoethyl methacrylate (IEM) alone or copolymerizing with various vinyl unsaturated monomers optionally in the presence of epoxy-amine adduct. These cation-active polymers when acidified or partially acidified provide aqueous solutions or dispersions especially useful as low temperature curable vehicles in cathodic electrocoating.

Abstract: New aqueous dispersible cathodic electrocoat resin compositions containing both secondary amine and 1,3-benzoxazine functionality cure by oxazine self-additon and/or oxazine/amine reactions. Such compositions are prepared in a multi-stage process to give corrosion and chemical resistant coatings which exhibit good package (tank and feed) stability.

Abstract: Package and tank stable, low temperature self-curing, cation-active aqueous soluble or dispersible coating compositions are prepared by copolymerizing blocked meta-isopropenyl-.alpha.,.alpha.-dimethylbenzyl isocyanate (m-TMI) with various vinyl unsaturated monomers optionally in the presence of epoxy-amine adduct. These cation-active polymers when acidified or partially acidified provide aqueous solutions or dispersions especially useful as low temperature curable vehicles in cathodic electrocoating.

Abstract: An electrocoating composition useful for electrocoating a paint coating from an aqueous solution onto an anode electrical conductive substrate. The electrocoating composition is based upon a fatty acid ester and .alpha.,.beta.-unsaturated dicarboxylic acid modified styrene-allyl alcohol copolymer further modified with an acid-functional acrylic copolymer. The electrocoated film can be air dried or heat cured.

Abstract: The invention pertains to thermosetting powder paint compositions adapted to fuse and thermoset upon exposure to heat. The powder paint is based upon a one-component, self-curing polymeric binder comprising a thermosetting glycoluril copolymer containing methylol or alkoxy methyl glycoluril groups adapted to cross-link with reactive hydroxyl, carboxyl, or amide groups on the copolymer. The copolymer is produced by partial condensation of tetramethylol or tetra-alkoxy methyl glycoluril with units containing reactive hydroxyls, carboxyls, or amide groups.

Abstract: The invention pertains to thermosetting powder paints adapted to fuse and thermoset upon exposure to heat. The powder paint is based upon a two-component binder system comprising a polymeric glycoluril adapted to cross-link a matrix polymer having reactive hydroxyl, carboxyl, or amide groups.

Abstract: Aqueous heat-curable coating compositions comprise polyester resin, aminoplast resin, and an allyl ether of a diol or triol wherein the allyl ether alcohol functions as a conventional co-solvent for aiding in dispersing the polyester resin in water and under curing conditions becomes an integral part of the cured coating.

Abstract: A one-step process for synthesizing water soluble self-curing polyurethanes is achieved by co-reacting certain monomers under controlled conditions to form a blocked, water soluble polyurethane which can be subsequently dispersed in water. The polyurethane polymer is substantially free of high molecular weight hydrocarbon chains and essentially comprises all polyurethane units and is adapted to self-cross link upon being subjected to heat. The polymer is particularly suitable for producing polyurethane protective coatings which exhibit substantially increased film hardness, abrasion resistance, as well as other desirable film integrity properties.
