Abstract
The present invention provides a method of controlling an electrocoating bath using an ion exchange resin. The ion exchange resin is maintained in a porous container in a suspended state in the electrocoating bath, and is used in a quantity of not more than the chemical equivalent of excess counter-ion to be removed from the bath. Bath control is easily achieved without any coagulation trouble as often observed in conventional column methods.
