  • 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.

  • Polyoxyalkylenepolyamine reaction products and their use in cationic electrodeposition
    Patent number: 4689131
    Abstract: Ungelled reaction products of polyoxyalkylenepolyamies with monoepoxides and optionally with a polyfunctional material which contains groups capable of reacting with amino and/or hydroxyl groups are disclosed. The reaction products can be neutralized with acid and dispersed in aqueous medium where they are useful as additives for cationic electrodeposition baths to improve surface appearance of electrodeposited coatings.
