In this method, a process on the surface of zinc, zinc-iron, or zinc-nickel produces a defined thin and durable passivation coating, which enhances corrosion resistance. The different passivation processes differ with regard to corrosion protection, appearance, coating thickness, and coloring.
Passivation Chemicals In order to obtain maximum corrosion resistance over phosphate coatings, it is necessary to apply a post-treatment in order to seal the parts.
- Evercure It is a passivating chemical for pickled surface. It produces passivating film on derusted surface of iron and steel. It protects iron and steel from rusting in-between surface.
- Everfix Everfix is a passivating chemical for painting surface. In order to obtain maximum corrosion resistance over phosphate coatings, it is necessary to apply a post-treatment in order to seal the parts. chrome passivation non-chrome passivation
