Binder system for electrodeposition coating

The invention relates to aqueous electrocoating baths containing synthetic resins capable of deposition on the cathode. The electrocoating baths according to the invention are characterized in that they contain a homopolymer or copolymer of an alkyl vinyl ether of the general formula CH.sub.2 .dbd.CH--O--R wherein R represents an alkyl radical having 2 to 4 C atoms.

Aqueous electrocoating baths containing synthetic resins capable of

The invention relates to a process for coating electrically conductive substrates, in which aqueous electrodeposition paints containing 1 to 15 percent by weight of electrically conductive carbon black and/or graphite having a primary particle diameter of less than 10 .mu.m in combination with up to 12 percent by weight of zinc powder or zinc flakes, with the percentages by weight relating to the total amount of binder and--if present--crosslinking agent contained in the electrodeposition paint, are employed.

Process for coating electrically conductive substrates, and an aqueous,

A synthetic resin is in the form of a metal complex compound. The resin is the reaction product of:

Synthetic resin

Coating bath and method for cataphoretic coating of metallic iron surfaces from aqueous solutions and/or aqueous dispersions of salts of cationic film-forming agents. An additional content of metallic ions from metallic salts is dissolved in the coating bath, the potential of which in the electrolytic voltage series of the cations is higher than the potential of the iron metal surfaces.

Coating bath for the cataphoretic coating of metallic surfaces

Method of cataphoretically coating the surfaces of electrically conducting substrates acting as cathodes in an electrical lacquering bath based on aqueous solutions and/or aqueous dispersions of salts of cationic film forming agents with organic and/or inorganic acids wherein the coating bath contains chloride ions dissolved therein with nitrate ions, nitrite ions, or a mixture of nitrate and nitrite ions in a weight ratio from about 0.01 to 8 parts of chloride ions to 1 part of nitrate ions, nitrite ions, or a mixture of nitrate and nitrite ions.

Process for cataphoretically coating the surfaces of electrically
