Specification

Zinc flake coatings are chrome (VI)-free corrosion protection coatings for commercial vehicle construction, construction machines, agricultural vehicles and equipment, and all other fields that require vehicle construction standard corrosion protection requirements.

The corrosion resistance of ZFHSL is as follows:

Diameter ≥ M6 - 480h*

Diameter ≥ M10 - 720h*

* Guideline values: No base metal corrosion at points without thread in salt spray mist testing according to DIN EN ISO 9227 NSS.

The designation ZFSHL refers to the following corrosion coating:

Zinc flake coating, with top coat, silver colour, with lubrication that alters the friction coefficient.

Adjusted friction coefficient range from 0.09μ - 0.14μ due to top coat with integrated lubricating particles
