Transparent Passivation for Zinc-nickel Alloy Plating

ZN-300

 

The ZN-300 is a trivalent chromium black passivator used after zinc-nickel plating. It can form a uniform black passivation layer on zinc-nickel alloy.


It contains trivalent chromium compounds but does not contain hexavalent chromium and fluorides.

The ZN-300 should be used together with the subsequent sealants (e.g. the Schloetter SLOTOFIN Series) to further strengthen the anti-corrosion ability and make the black coating appear more glossy.
