ZinKlad 500 is a unique, hexavalent chromium-free coating system that will meet today’s industry demands for high performance surface treatments. It combines a metallic zinc-iron deposit of 8 microns minimum thickness, with a high build iridescent passivate and clear topcoat. The unique properties of ZinKlad 500 consistently meet minimum performance demands for corrosion and torque modification.

ZinKlad 500 deposits are applied exclusively using our Enviralloy Fe electroplating processes. This unique chemistry is formulated to provide uniform, bright and adherent zinc-iron deposits that is uniform bright and ductile with outstanding plate distribution characteristics.

ZinKlad 500 systems are completed with the application of a high build trivalent passivate followed by a specialist topcoat layer.

MacDermid TriPass ELV range of high build trivalent passivate films impart a silver-iridescent colour, whilst extending corrosion resistance against the formation of white rust.

MacDermid HydroKlad, JS and Torque’n’Tension branded topcoats provide increased corrosion resistance, they modify surface tribology to ensure uniform torque and clamping characteristics.
