In the current condition of high environmental protection requirements, traditional Cr(VI) passivators are gradually being eliminated from the market due to their toxicity and pollution.
Bigely trivalent chromium blue zinc passivator BZ-212 is a new type of environmentally friendly passivation agent, which can effectively avoid the formation of hexavalent chromium in the passivation film layer, thus meeting the environmental protection requirements and market demands.
Features of blue zinc passivator BZ-212
1. The passivation film is colorful, meticulous and good corrosion resistance. BZ-212 adopts a good trivalent chromium formulation technology to form a stable trivalent chromium passivation film on the surface of the galvanized layer, which effectively prevents white rust and improves the protection performance.
2. Wide operation range, passivation time on automatic line is 25-45 seconds, PH can be controlled between 2.0-2.8.
3. This product can be used for acid galvanizing and alkaline galvanizing, especially suitable for the passivation process of large-area workpieces on automatic lines such as ring lines and vertical lifting lines.
