Abstract: An improved process for the preparation of cationic resins derived from polyepoxides is disclosed. Typically, the process comprises contacting the polyepoxide with particular polyether polyols and heating the two together to form a resin which may then be reacted with a cationic base group former such as an amine and acid. Aqueous dispersions of the cationic resins prepared by the improved process are useful for coating applications, particularly cationic electrodeposition. They exhibit good low temperature cure response and the cured coatings have good physical properties such as resistance to water, detergent and salt spray corrosion.

Abstract: Novel compositions of matter comprising a water-dispersible reaction product of beta-diketones and epoxy material are hereby provided. The beta-diketones useful herein are those which enolize in amounts that render them sufficiently acidic and reactable with epoxy groups of the resin. The novel reaction products can be dispersed in water and they can be formulated optionally with curing agents. Ferrous metals treated with the compositions of this invention exhibit excellent corrosion-resistant properties.

Abstract: Quaternary ammonium hydroxide-containing polymers and their use in coating applications are disclosed. The quaternary ammonium hydroxide-containing polymers are prepared from reacting a polyglycidyl ether of a cyclic polyol with a tertiary amine in the presence of a sufficient amount of water for the formation of quaternary hydroxide groups.The quaternary ammonium hydroxide-containing polymers are particularly good as electrocoating resins in that they electrodeposit without generating acid counterion. They are also good in other conventional coating applications such as dip, flow, spray and roll coating in that the resulting coating can be baked without the generation of corrosive acid.

Abstract: A method of cationic electrodeposition on an electroconductive substrate is disclosed. The method of the invention employs as the electrocoating vehicle an aqueous dispersion of a quaternary ammonium carbonate-containing resin. Electrodeposition of the resin is accomplished without generating harmful acid from the counter ion. The carbonate counter ion is continuously evolved from the electrodeposition bath at the anode as carbon dioxide.The quaternary ammonium carbonate-containing polymers are also useful as feed resins for controlling the pH of aqueous dispersions of acidified cationic resins used in electrodeposition. Upon electrodeposition, these resins generate acid which can build up to undesirable levels in the electrodeposition bath. The quaternary ammonium carbonate-containing polymers are relatively basic and when fed into the bath react with the acid to form the corresponding quaternary ammonium salt of the acid releasing carbon dioxide.
