ABSTRACT:
Cathodic coating agents which are rendered water-dilutable by the addition of an acid, contain binder systems possessing basic nitrogen groups and may or may not contain pigments, dyes, fillers, solvents, antioxidants, other surface coating assistants and/or additional crosslinking components, the binder system containing sulfonate and/or phosphonate groups or the esters of these groups in an amount of from 0.05 to 3% by weight, and the preparation of such products.
The novel coating agents are useful for the cathodic electrocoating of electrically conductive substrates.
