ABSTRACT:
1 Process for producing a catalyst paste for cathodically separable electrophoretic dipping lacquers.
2.1 Use was made of dibutyltin oxide by way of a catalyst paste for electrophoretic dipping lacquers, dispersed in pasting binders. An object is to provide a new process for producing such catalyst pastes while saving time and energy.
2.2 A process is provided for producing a catalyst paste for cathodically separable electrophoretic dipping lacquers, wherein the dibutyltin oxide is first pre-dispersed with an organic solvent and an organic acid such as is commonly used for neutralizing cathodically separable electrophoretic dipping lacquers, whereupon it is dispersed with the pasting binder and water and ground.
2.3 Cathodic electrophoretic dip lacquering making use of catalyst pastes containing dibutyltin oxide.
