    摘要: An aqueous dispersion based on an acid-protonized reaction product from(a) Mannich bases free from epoxide groups, from(a.sub.1) condensed phenols free from ether groups with at least two aromatic rings and with at least two phenolic hydroxyl groups and/or(a.sub.2) condensed phenols, containing ether groups, with at least two aromatic rings and at least one phenolic hydroxyl group(a.sub.3) secondary amines with at least one hydroxyalkyl group, possible in a mixture with(a.sub.4) secondary dialkylamines or dialkoxyalkylamines without free hydroxyl groups,(a.sub.5) formaldehyde or compounds splitting off formaldehyde, with(b) epoxide resins, aliphatic hydroxyl groups from (a) and/or (b) being converted at least in part into urethane groups possibly by reaction with partly blocked isocyanates,containing furthermore fine-particulate non-ionic plastics in dispersed form. The dispersion and/or the fine-particulate plastics furthermore may contain pigments and/or fillers. The dispersion is suitable as an electro-dip means for coating on electrically conducting substrates acting as the cathodes in an electro-dip enameling process.

    摘要: A process and apparatus for the preparation of aqueous synthetic resin dispersions by using water to precipitate the synthetic resins from their solutions in water-miscible solvents. The solutions may contain pigments, extenders, and additives. The precipitated solids are separated off and dispersed uniformly in an aqueous medium. The precipitation of the synthetic resins is carried out in the presence of inert grinding bodies.
