Trivalent Chromium Blue Passivation Chemical
Model No.: HN-68D
Introduction of Trivalent Chromium Blue Passivation Chemical:
I.M.T.'s trivalent chromium blue passivation agent provides outstanding corrosion resistance to the zinc plated substrates without any hexavalent chromium, which can meet the environment protection standard. I.M.T. trivalent blue chromium passivation process pass the test of 72-hour neutral salt spraying(NSS test).
Advantages of Trivalent Chromium Blue Passivation Chemical:
1.It is completely free of Cr+6 and meets the product requirement of European, United States, Japan, etc.
2.The passivation film has excellent corrosion resistance and can pass 72-hour neutral salt spray test(NSS test).
3.It is suitable for acid zinc plating and alkaline zinc plating using rack or barrel plating under normal temperature..
4.The passivation solution can be used for a long time by replenishment based on consumption.
