A process for painting integrated automobile and commercial vehicle bodies or cabins which comprise plastic parts. The metal parts of the body/cabin are provided with an electrocoat and are integrated with the plastic parts. These plastic parts either already have an electrically conductive aqueous primer coat or an uncured electrically conductive aqueous primer film or are unpainted. Primers are applied to the metal and plastic parts. Atop the primers, a basecoat and a clearcoat are applied.

Integrated coating method for auto body parts containing plastic parts or for cabins of passenger cars and utility vehicles as well as for their replacement parts and add-on parts

A method of removing, by oxidation at the anode, the acid liberated in cathodic dip-coating in the course of the deposition of the coating film, using anodes coated with a layer of tin oxide or with a mixture of tin oxide with ruthenium or iridium oxides.

Method of removing acid formed during cathodic electrodip coating

The present invention relates to a novel process for coating objects by means of direct current, in which process an adjustable DC voltage is pulse-modulated with an adjustable AC voltage. The process is useful for electrochemical coating of objects with resinous coating material. Preferably, the pulse modulation of the DC voltage is limited to certain time intervals during the coating process and the pulse modulation is connected and disconnected with an adjustable duty ratio.

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.
