Zinc flake corrosion protection is a Chrome (VI)-free standard in the automotive field. HCP zinc flake coatings offers superior corrosion protection for high tensile steel without hydrogen-induced embrittlement. Constant coefficient of friction, dimensional stability and selection of colours are additional outstanding HCP properties.
This zink flake system consists of a basecoat and a topcoat. Depending of the requirements, a corrosion resistance according to the salt-spray test (DIN-EN-ISO 9227) of at least 720 hours is possible. Sealing systems developed specifically to complement the functionality enabling good sliding and non-stick properties, can also be applied.
Standard colors are silver and black.
Dörken MKS® is the supplier of the coatings.
