HEXAVALENT CHROMATE conversion surface treatment of zamak alloys

- Improves paint adhesion
- Reasonable resistance to salt fog
- Contains Chromium III
- Matte grey appearance
- It does not change the part's original roughness

Properties and characteristics
Passivation of zamak is used to protect the alloys from corrosion generated by atmospheric elements; it is highly resistant to salt fog (it reaches 96 hours without being attacked), it does not change the roughness of the part, it is matte and grey in colour, variable depending on the alloy used.
Slight differences in the appearance of the product do not compromise its efficiency and operating performance.
Each alloy reacts with the passivation bath to generate a coating characteristic of the alloy.
Best used as a painting primer, the deposit contains chromium III (trivalent).

Applications
Mechanical, electromechanical, aviation, space, agricultural, nautical, etc..

Operating conditions
It can be used as a priming coat for painting or as a final treatment, depending on the use.
