Cathodic dip coating

The environmentally friendly coating solution for components with complex geometries.

This electrochemical process coats the object by applying direct voltage across it in a dipping bath. The result is a highly uniform coating of constant thickness and optimal surface quality on metal surfaces and in cavities.

The essential properties at a glance

• low solvent content, so environmentally friendly
• suitable for various metals (steel, light alloys, nonferrous metals)
• ideal coating for components with complex geometries
• resistant to solvents and insensitive to alkalis and acids
• excellent corrosion resistance
• uniform, reproducible coating from 10 µm possible
• thick layer cathodic dip painting up to 50 µm possible
• coating also suitable for decorative purposes
• electrically insulating effects

With optimal processes to the ideal surface

• excellent priming for downstream powder coating
• enhanced corrosion protection in conjunction with the pretreatments: zinc, zinc + phosphate, zinc-nickel, and zinc-nickel + phosphate
• inhouse plant with series-connected cycle type machine including specific pretreatment equipment

A wide range of cathodic dip painting combinations, for example

• Blasting
• Degreasing
• Pickling
• Passivating
• Phosphating
• Anodising
• Galvanising
• Galvanising + phosphate
• Zinc-nickel
• Zinc-nickel + phosphate
• Powder coating
• Wet coating
