Abstract: Polyadducts/polycondensates which can be diluted with water when protonated with an acid and which contain basic nitrogen groups are obtained by the polyaddition reaction of (A) a Mannich base obtained from (a) a monophenol and/or a polyphenol, (b) one or more dialkylamines of the formula where R1 and R2 are each alkyl or alkoxyalkyl, or are linked to one another to form a 5-membered or 6-membered ring, and (c) formaldehyde with (B) an epoxy resin and contain groups, which are bonded to aromatic rings, of the general formula and may or may not contain groups of the general formula where R3 and R4 are each alkyl, hydroxyalkyl or alkoxyalkyl, or are linked to one another to form a 5-membered or 6-membered ring, and R5 and R6 are each hydrogen or methyl. These products are useful as binders for the cathodic electrocoating of metallic 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: A polyadduct/polycondensate, which is water-dilutable when protonated with an acid, and which contains basic nitrogen groups, is obtained by polyaddition reaction of (A) Mannich bases obtained from monophenols and/or polyphenols, one or more secondary amines which contain one or more hydroxyalkyl groups, or a mixture of such a secondary amine with another secondary amine, and formaldehyde or a formaldehyde donor, with (B) an epoxy resin, the polyadduct/polycondensate of (A) and (B) containing groups, bonded to aromatic rings, of the formula (I) (I) with or without groups of the general formula II (II) where R1 is a polydienyl radical, R2 and R3 are hydrogen or methyl and R4 and R5 are alkyl, hydroxyalkyl or alkoxyalkyl or are linked to one another to form a 5-membered or 6-membered ring. The polyadduct/polycondensate can be used, for example, as a surface-coating binder for the cathodic electrocoating of metal articles.

Abstract: Self-crosslinking cationic bonders for cathodically electro-dip lacquering conductive metal particles are prepd. by (i) reacting (A) NH3 and epoxide cpd. reaction prods. having formula R-E1-(NH-E1)n1-R (I), cpd. (II) and/or cpd. (III) (where R is 1-12C S- alkyl, PhO- or 1-18C-alkyl-phenoxy; E1 are OH gp.-contg. divalent and E2 OH gp.-contg. tri-or tetravalent gps., as obtd. by opening the oxiran rings of epoxide cpds. contg. 2,3 or 4 epoxide gps./mol. n1 is 1-5; n2, n3, n4 and n6 are 0-3 and n5 is 1-3 and x is 0 or 1) with (b) partly or fully blocked di- or polyisocyanates, and opt. with (C) di- or polyamines; and (ii) protonising with acid. Lacquer binders, opt. combined with pigment pastes, yield hard, scratch-resistant, adherent, elastic coatings which resist solvents and corrosion.

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.
