                      ZN-T40 transparent passivation solution (it can be used for Zinc nickel passivation).


                      Technology:

                      1、It contains trivalent chromium compounds, and it does not contain hexavalent chromium and fluorine.
                      2、We use SLOTOFIN 11 or SLOTOFIN 22 as sealing process for sealing after passivation technology.
                      3、Test tell us that we conduct 120℃ aging for 24 hours, the anti-corrosion performance of rack plating could reach up to 240 hours, barrel plating could reach 120 hours (white rust) (according to DIN 50021 SS standard).
