Abstract:
In an electrocoating process acid binders which are present at least partly in the form of their salts with basic compounds are used and the basic compounds used for salt formation consist of the extent of 0.1 to 50 percent of the neutralization equivalent of the acid binder of at least one arylamine and/or alkynylamine and/or quaternary ammonium hydroxide and/or phosphonium hydroxide with at least one aromatic ligand, and other conventional additives and non-basic corrosion inhibitors may be contained in the aqueous solution or dispersion of the coating composition. The process is suitable for the production of particularly corrosion-resistant coatings on metal articles.
