 Chromium-Free Passivating Agent
Hexavalent chromium is a carcinogen, traditional hexavalent chromium craft is very harmful to the environment and the human being. Chromium-free passivating agent is a water-based chromium-free pre-treatment chemical, which can substitute traditional hexavalent chromium conversion coating.


The chromium-free passivating agent has good adhesion with the matrix, which form a layer of colorless membrane at the surface of zinc plate and Al-Zn plate and add corrosion resistance to the baseplate, it contains no hexavalent chromium and trivalent chromium at all, in line with the environment protection requirement and can be used in zinc coated steel, aluminum and zinc coated alloy steel, cool-rolled steel plate, aluminum sheet continuous roll coating or spray unit.


The chromium-free passivating agent has a good tolerant to the zinc and iron ion in the passivation base, thus the usage life span of the passivation base is longer; the waste is easy to handle and the handling cost is low.
