ABSTRACT:
Cationic cathodic electrocoat is conducted by using a cationic electrodepositable paint bath having a pH value of about 6.0-8.0 and by supplementing the bath with a supplemental feed paint prepared by mixing a filtrate obtained by filtering the above described electrodepositable paint bath and a supplemental feed electrodepositable paint having a lower neutralization equivalent than the former electrodepositable paint to dissolve and disperse said paint to obtain a dispersion and then diluting homogeneously the obtained dispersion with the bath derived from the above described paint bath, whereby the property values of the electrodepositable paint bath are controlled.
