ZinKlad™ 250 M
Ford S-437 compliant
High performance mechnical zinc plate, trivalent passivate and topcoat
|
ZinKlad™ 250 M is a hexavalent chromium-free coating system that will meet today's industry demands for high performance surface treatments. It combines a mechanically plated metallic zinc deposit of 8 microns minimum thickness, with a high build iridescent passivate and clear topcoat. ZinKlad 250 M consistently meets minimum performance demands for corrosion and torque modification. |

ZinKlad 250 M deposits are applied from our MacuGuard mechanical zinc 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 250 M 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 color, whilst extending corrosion resistance against the formation of white rust. JS and Torque'n'Tension topcoats provide increased corrosion resistance and modify surface properties to ensure uniform torque and clamping characteristics. |
Minimum corrosion performance as plated for 8 micron coating, measured against salt spray ASTM B117: "part geometry, substrate quality and post plate handling can have an effect on finish performance" |
