  • ELECTRODEPOSITABLE COATING COMPOSITIONS
    Publication number: 20220363917
    Abstract: The present invention is directed to an electrodepositable coating composition comprising an acrylic polymer comprising greater than 60% by weight of constitutional units comprising the residue of a hydroxyl-functional (meth)acrylate monomer and/or a hydroxyl-functional (meth)acrylamide monomer, based on the total weight of the acrylic polymer; and an ionic salt group-containing film-forming polymer different from the acrylic polymer. Also disclosed are coatings, coated substrates, and methods of coating a substrate.

  • Layer of reaction product of epoxy and phosphorus materials and curing agent on substrate
    Patent number: 7476444
    Abstract: A corrosion resistant, alkali resistant coating composition is disclosed. The composition comprises a binder comprising a reaction product of an epoxy-containing material and a phosphorus-containing material together with a curing agent. Aminoplasts, especially melamine-based aminoplasts, are particularly suitable curing agents. A source of silicon can optionally be included. The compositions also provide excellent adhesion and can be used with or without a weldable primer. The compositions are applied to and cured on a metal substrate.

  • Products obtained from the reaction of amine-diol and a polyfunctional substance and application of such products to electroapplicable cationic paint compositions
    Patent number: 5348578
    Abstract: Product obtained from the reaction of(a) an amine-diol resulting from the reaction of a primary amine having the formula R-NH.sub.2 in which R represents an aliphatic or aromatic radical, with at least one alkylene oxide comprising predominantly propylene oxide, and(b) at least one polyfunctional substance, capable of acting on the hydroxyl groups of said amine-diol.The product disclosed may be used as an additive in an electrodeposition paint composition in order to furnish, after application to a metal substrate, a coating or film having an improved resistance to pinholes and to cratering.
