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.

Acrylic and acrylic/epoxy copolymer composition as self-curing cathodic

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.

Self-curable benzoxazine functional cathodic electrocoat resins and

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.
