In the electrolytic coating of components with direct current, we distinguish between cathodic dip coating and anodic dip coating. In both methods, the paint film is deposited on the object surface from an aqueous paint emulsion in an immersion bath by the action of DC current. In anodic electrophoretic coating the paint material is the anode, while in cathodic electrophoretic coating the paint material is the cathode in the electrical DC circuit. When current flows, the paint emulsion in the acid boundary layer or alkaline boundary layer coagulates and forms a highly adhesive paint film that is hard and corrosion-resistant.

Make use of the advantages of electrophoretic coating: the high environmental friendliness, the efficient application of water-soluble coatings, the good coverage of complicated geometries as well as the high degree of automation.
