| titleOfInvention | Water-dispersible binders for cationic electrocoating varnishes, and process for their preparation |
| abstract | The invention relates to water-dispersible binders which are intended for cationic electropaints and are based on reaction products which are formed from modified epoxy resins and primary and/or secondary amines and which can, if desired, also contain crosslinking agents, pigments, flow-control agents and other customary auxiliaries. The reaction products have been prepared by reacting (A) Low molecular weight epoxy resins which contain aromatic groups and have an epoxide equivalent weight of less than 375 with (B) aliphatic and/or alicyclic polyfunctional alcohols or carboxylic acids having a molecular weight of less than 350 by addition to the epoxy group in such a way that the reaction products contain 10-45% of aromatic groups, calculated as phenylene group, and reacting the reaction products of A and B with (C) if desired up to 60% by weight, relative to total binder, of polyfunctional alcohols, carboxylic acids and/or SH compounds having a molecular weight of 300-5,000, the molar ratios of (A), (B) and, if desired, (C) being chosen in such a way that the resulting intermediate product has terminal epoxy groups, (D) by reacting the intermediate product by the addition of a phenolic hydroxyl group of a monophenol and/or diphenol to the epoxy groups, the monophenol or diphenol having as a substituent on the aromatic ring(s) at least one grouping of the general formula <IMAGE> (I) in which R1 and R2 are identical to or different from one another and represent hydrogen or a methyl group, and by adding a primary and/or secondary amine before or after the reaction of the phenolic hydroxyl groups with the epoxy groups, to at least some of the double bonds of the grouping of the formula (I). |
