Cathodic dip coating (CDC) stands for an electrochemical surface treatment process during which the deposited, heavy-metal free coating is crosslinked during the burn-in process in the oven. CDC coated surfaces produce lower coating thicknesses with highly efficient black base coats and high corrosion protection.
Good adhesion quality at poorly accessible spots and cavities guarantees even layer distribution and great corrosion protection against fuels, brake fluids and oil. CDC coatings combine long-term protection with high economic efficiency.
It is therefore one of the most preferred surface treatment finishes.
Integrated pickling during the coating process is optional – our CDC surface treatment finish is therefore highly suitable for large and complex special assembly groups/modules and welded parts.

Special treatment with part-specific processes possible.
During the upstream pre-treatment process, the parts pass through an 11-zone-facility in which alkaline degreasing and zinc-phosphate are applied with a special spraying technique.
Applied fields of CDC surfaces:
- large, complex special assembly groups/modules with integrated pickling process, e.g. front axle carrier, body parts
- automotive and supplier industries up to 800 kg of individual weight, e.g. interior, body, chassis, engine and fuel systems
- utility vehicles
- electrical industry
- construction machinery
