Zinc flake coatings are chromium(VI)-free corrosion protection coatings for commercial vehicle construction, construction machinery, agricultural vehicles and equipment, as well as all other areas that require corrosion protection at vehicle construction level.

The corrosion resistance of ZFSHL is:

• Diameter M6 - 480h*


• Diameter M10 - 720h*

• * Guide values: No base metal corrosion at non-threaded locations in the salt spray test according to DIN EN ISO 9227 NSS.

The designation ZFSHL refers to the following corrosion coating:

• Zinc flake coating, with topcoat, color silver, with friction-adjusting lubrication.


• Set friction coefficient window of 0.09 0.14 through topcoat with integrated lubricating particles
