Abstract

Adducts obtained by reacting an epoxide compound with guanidine or a guanidine derivative, using not less than 1 mole of guanidine or guanidine derivative per epoxide equivalent of the epoxide compound; the adducts may or may not be partially or completely neutralized by adding acid, and may additionally contain blocked isocyanate groups. The novel adducts may be used, in combination with a completely blocked polyisocyanate, aminoplast resin and/or phenoplast resin, as binders in coating agents, and for the cathodic electrocoating of metal articles.
