Abstract: Self-crosslinking cationic binders for the cathodic electrodip lacquering of metallically conductive articles are prepd. by (i) reacting (A) addn. prods. of NH3 and epoxide cpds. with (B) partly or fully blocked di- or polyisocyanates, opt. with (C) di- or polyamides, and (ii) protonising with acid, esp. a carboxylic acid. (A) have formulae R-E1-(NH-E1)n1-R (I), (where R is 1-12C S-alkyl, PhO- or 1-18C-alkyl-phenoxy; E1 are OH gp.-contg. divalent- and E2 are OH gp.-contg. tri- or tetravalent gps. are obtd. by the ring opening of 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).

Abstract: The invention concerns polyadducts and their use. The polyadducts, possessing nitrogen-basic groups, have a mean molecular weight of from 500 to 10,000 and contain groups, attached to aromatic rings, of the general formula (I) (I) where R1 and R2 are identical or different and each is hydrogen or methyl. In particular, these polyadducts are used, after protonizing with an acid, as binders for the cathodic electrocoating of metal articles.

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: 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: An aqueous cationic surface-coating system contains an olefinically unsaturated surface-coating binder having basic nitrogen groups, some or all of which are converted into salts with acid, a Co, Mn, Pb, Ce, Zr, Ca, Zn, Fe, Al, Cu, Ni or Cd complex, if appropriate in combination with an inhibitor and/or an initiator which supplies free radicals. This surface-coating system can be used for cathodic electrocoating or for conventional methods of surface-coating.

Abstract: A process for the preparation of curable polyadducts, possessing basic nitrogen groups, wherein (A) monophenols and/or polyphenols, which contain groups of the general formula (I): where R1 and R2 are identical or different and each is hydrogen or methyl are reacted with (B) amines having one or more primary and/or secondary amino groups, and the adduct formed is reacted with (C) epoxide compounds having from 1 to 4 epoxide groups per molecule and having a molecular weight of at most 2,500, the ratio of the phenolic hydroxyl groups of (A) to epoxide groups of (C) being from 1:0.5 to 1:2 and the amine (B) being employed in such amount that the resulting polyadduct of (A), (B) and (C) contains from 0.1 to 5% by weight of basic nitrogen, and the use of the products, after protonation with an acid, as binders for the production of coatings, especially for the cathodic electrocoating of metal articles.

Abstract: A process for the preparation of self-crosslinking, cathodic electrocoating binders by reacting polyether-polyols, which may or may not contain thio groups, with semi-blocked diisocyanates or partially blocked polyisocyanates, wherein the reaction products (A), containing blocked isocyanate groups, are reacted with a polyamine (B), some of whose amino groups may or may not be in the form of ketimine groups, in such a way that one or more amino groups of the polyamine (B) form a urea group with a blocked isocyanate group of the reaction product (A), and the self-cross-linking reaction product of (A) and (B) is converted into a water-dilutable form in the conventional manner by protonization with an acid. The coating binders prepared according to the invention may be used for cathodic electrocoating of metal articles.
