PROCESS FOR ELIMINATING SURFACE-DEFECT INDUCING CONTAMINANTS FROM ELECTROPHORETIC COATING BATHS

摘要

A process for removing from electrocoating baths impurities which cause surface defects. The invention relates to a process for removing from electrocoating baths impurities which cause surface defects, wherein the electrocoating paint, in addition to the purification operations which are already conventional, is filtered without pressure through an adsorbent which adsorbs hydrophobic substances having a surface tension
