Zinc-flake coatings are chromium (VI)-free corrosion protection coatings for commercial vehicle construction, construction machines, agricultural vehicles and equipment, and all other fields that have vehicle construction standard corrosion protection requirements.
Corrosion resistance for ZFSH is as follows:
- Diameter ≥ M6 - 480h*
- Diameter ≥ M10 - 720h*
- * Guideline values: No base metal corrosion at sites without thread in salt spray mist testing according to ISO9227 NSS
The name ZFSH has the following meaning:
Zinc flake coating, with top coat, silver colour, no lubrication that alters the friction coefficient.
DIN 9021 has been replaced by international standard DIN EN ISO 7093-1.
Nominal sizes 2.5 and 7 are no longer included in DIN EN ISO 7093-1 and therefore remain valid as DIN 9021.
