    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: 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, free from epoxide groups, are obtained from ammonia and epoxide compounds by reacting 1 mole of ammonia with from 1.2 to 2.0 equivalents of epoxide, so that if diepoxide compounds are used products of the general formula (I) are obtained, while if triepoxides and/or tetraepoxide compounds are used, by themselves, or together with diepoxide compounds, products of the general formula II (II) are produced; in these formulae, the E1's are identical or different hydroxyl-containing divalent radicals and the E2's are identical or different hydroxyl-containing trivalent or tetravalent radicals, resulting from the opening of the oxirane rings of epoxide compounds containing two, three or four epoxide groups in the molecule, n1, n3 and n5 are from 0 to 3, n2 and n4 are from 1 to 3 and X is 0 or 1, and one or more of the divalent radicals E1 in the general formlula (II) may or may not be replaced by polyvalent radicals E2. The novel polyadducts can be modified by reaction with aldehydes, ketones, monoepoxide compounds, carboxylic acids, carboxylic acid esters or isocyanates, or by protonation with an acid, and may be used, for example, for the cathodic electrocoating of metallic articles.
