                       >ZN-T71 original passivation solution of trivalent chromium (it can be used for Zinc nickel passivation).



                      ZN-T71 original passivation solution of trivalent chromium (it can be used for Zinc nickel passivation).


                      Technology:
                      1、ZN T70 technology could produce even and uniform passive film with excellent anti-corrosion performance on the plating layer of zinc-nickel alloys.
                      2、Plating layer could meet anti-corrosion requirements of DIN EN ISO 9227, after 24 hours aging at 120℃, anti-corrosion of rack plating reach up to 360 hours, while barrel plating reach up to 120 hours.
                      3、After passivation, we conduct post settlement in confining liquid (such as our SLOTOFIN), it could improve anti-corrosion ability.
                      ??
                      Next:ZN-T40 transparent passivation solution (it can be used for Zinc nickel passivation).
