ZinKlad 250M is 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 passivate and clear topcoat. The unique properties of ZinKlad 250M consistently meet minimum performance demands for corrosion and torque modification..

ZinKlad 250M uses mechanically applied zinc deposited from our world renowned MacuGuard process. This provides an economical bulk method for applying zinc coatings onto metallic substrates. Deposit appearance is semi-bright with excellent corrosion protection which is free from hydrogen embrittlement.

ZinKlad 250M mechanical zinc 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’Tensionbranded topcoats provide increased corrosion resistance, they 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:
