Abstract: The coating compsn. based on a polymeric binder (I), which can be diluted with water, contains 0.1-25, pref. 0.5-15 wt.%, w.r.t. (I) of an ester diol (II) of the formula HOCH2-CR1R2-CH2-O-CO-CR3R4-CH2OH (in which R1-4 independently are 1-8C alkyl gps.). (I) pref. is an acrylic ester copolymer contg. COOH gps. and neutralized with an amine. Used for the prodn. of coatings by electrophoretic deposition on metals. The gloss retention as the bath ages is good and there is no need to add solvents or flow aids later. There is almost no environmental pollution, as (II) are incorporated in the film. (II) also improve the flow of the film without impairing the dielectric strength and spread.

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: A resinous binder for varnish substantially free from oxide gps. is prepd. by reacting a Mannich base derived from a condensed phenol (I), a secondary amine (II) and a formaldehyde source, with an epoxide resin contg. 0.6-1.3 epoxide gps. per mol. (I) (I) is pref. of formula (I) (where OH is o or p. to X and X = 1-3C alkylene, SO2, SO or O). (II) comprises at least one sec. amine contg. is not 1 OH gp. with (out) other sec. or prim. amines. For cathodic electro dip-coating of metals, esp. electrical conductors. The resin is easy to manufacture and stable in store. The varnish ionised by acidification is highly bath-stable. Coatings after heat-hardening adhere strongly to substrates and are tough, elastic and scratch resistant.
