ABSTRACT:
Binder systems suitable for electrocoating and consisting of a base resin A which carries groups which can be protonated with acids or cationic quaternary groups and, if desired, hydroxyl or thiol groups, a crosslinking component B which carries at least two blocked isocyanate groups per molecule and an organic iron compound C which is partially or completely soluble in water, as a catalyst for the thermal crosslinking of components A and B, and if desired, an additive D which increases the catalytic activity of C, are used to prepare dispersions which are used for electrocoating.
