    Abstract: Surface-coating binders and their use. The binders are reaction products of (A) Mannich bases obtained from one or more condensed phenols, free from ether groups, which contain two or more phenolic hydroxyl groups per molecule, one or more butadiene or isoprene homopolymers or copolymers which contain one or more groups per molecule and have a mean molecular weight of from 500 to 6,000, one or more secondary amines which contain one or more hydroxyalkyl groups per molecule, or a mixture of such secondary amines with another secondary amine, and formaldehyde or a formaldehyde donor, with (B) one or more epoxy resins. These surface-coating binders are used especially for the cathodic electrocoating of metal articles.

    Abstract: A bath composition for cataphoretic electrocoating of conductive surfaces contains coating agents which have been rendered soluble or dispersible with acid, contain basic nitrogen groups and carry groups of the general formulae (1) and (11) (I) (II) and, optionally, also groups of the general formulae (III) and/or (IV) (III) (IV) where R1 and R2 are each alkyl, hydroxyalkyl or alkoxyalkyl, R3 and R4 are each hydrogen or methyl, R5 and R6 are each hydrogen, alkyl or a divalent radical of a polymer molecule which is bonded to a phenol or phenol ether, n1 is 1, 2 or 3 and n2 is 1 or 2, and where the oxygen bonded to the phenyl radical is either in the form of the OH group or etherified.

    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.
