DACROMET Coating Systems
DACROMET is the original zinc/aluminum flake coating. Classic DACROMET contains hexavalent chromium, so it does not meet F3393 or RoHS and has largely been replaced by GEOMET.
How to specify it
| Coating family | Zinc flake (ASTM F3393 / ISO 10683) |
|---|---|
| Maker | NOF Metal Coatings |
| Specify | Exact system: basecoat + topcoat + any lubricant |
| Why it matters | Friction and corrosion differ between grades of the same brand |
| Regulation | Contains Cr VI in its classic form: check before specifying |
