Abstract

Procedure for obtaining cathodically depositable coatings for the electro-immersion enamelling process, containing pigments, fillers, optionally additional hardening components and/or additives, characterized in that at 98-50% by weight, preferably 95-70% of weight of a modified cationic epoxy resin, after neutralization, partially or totally with inorganic and/or organic acids, dilutable with water, self-crosslinking, 2-50% by weight, preferably 5-30% by weight, are incorporated at room temperature, of a reaction product, which had been prepared by reacting a di- or triisocyanate with at least one equivalent (per NCO group) of a hydroxyalkylacrylate and at least one equivalent (per NCO group) of a saturated monoalcohol and/or unsaturated aliphatic, with at least 6 carbon atoms and/or a monocarboxylic acid saturated and/or unsaturated at 20-80ºC up to an NCO value of 0, presenting eldi- or triurethane formed, the general formula ** formula ** where R is an aromatic, cycloaliphatic or aliphatic hydrocarbon residue, R1 can represent a hydroxyethyl (meth) acrylate or a hydroxypropyl (meth) acrylic residue, R2 the residue of a saturated and/or unsaturated monoalcohol aliphatic with at least 6 carbon atoms and/or an alkyl or alkylene residue with at least 6 carbon atoms and n the value 1 or 2, and after homogeneous mixing, the materials are provided with additives and pigments, if provided, respectively, they are milled with them and after transformation of the basic groups into the salt form, the composition is emulsified, at 15-40ºC in water.
