Hexavalent Chromium-Free Coating System
Morgan Ohare is proud to offer ZinKlad 250, a unique, hexavalent chromium-free coating system that will meet today’s industry demands for high performance surface treatments. It combines a homogenous metallic zinc deposit of 8 microns minimum thickness, with a high build iridescent passivates and clear topcoat. The unique properties of ZinKlad 250 consistently meet minimum performance demands for corrosion and torque modification.
ZinKlad 250 deposits are applied from our specialist range of Environing and Kenlevel branded zinc electroplating processes. These are formulated to provide uniform, bright and adherent zinc deposits that are ductile and rapidly achieve minimum thickness for optimum coverage.
ZinKlad 250 zinc systems are completed with the application of a high build trivalent passivate followed by a special topcoat layer.
Trivalent Passivate and Topcoats
MacDermid TriPass ELV range of high build trivalent passivate films impart a silver-iridescent color, while providing corrosion resistance against the formation of white rust.
MacDermid HydroKlad, JS 500 and Torque’n’Tension branded topcoats provide increased corrosion resistance, modify surface tribology to ensure uniform torque and clamping characteristics.
Minimum corrosion performance as plated for 8 micron coating, measured against salt spray ASTM B117:
FWR: 144 hours
FRR: 500 hours
* part geometry, substrate quality and post plate handling can have an effect on finish performance
