Surface technology process: Passivation
Through the Conversion / Passivation coating, metals are covered with a non-metallic, Cr (VI) -free protective layer. In the HEICHEGROUP a variety of metal surfaces such as aluminum, magnesium, zinc die casting or steel can be passivated with a variety of procedures, including multi-metal pre-treatments. Conversion / passivation coatings offer excellent raw metal corrosion protection. Also, they are an ideal subsequent adhesive agent for additional coatings, adhesives and powder coatings.
We use this process for these materials:
Aluminum, Zinc die-cast
