Abstract: 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.ltoreq.35 mN/m--preferably homopolymers or copolymers of ethylene, propylene, but-1-ene or but-2-ene, which, if appropriate, contain further nonpolar comonomers.
