ZinKlad MG & MGL

High performance zinc plate, trivalent passivate and topcoat

 

 

 

ZinKlad™ MG / MGL are unique, hexavalent chromium-free coating systems designed to provide outstanding corrosion performance and minimize galvanic corrosion at the light metal interface.

They combine an homogenous metallic zinc deposit of 12 to 30 microns thickness, with a high build iridescent passivate and a multi-layer clear topcoat. ZinKlad MG / MGL consistently meet minimum performance demands for corrosion and torque modification.                                

  

ZinKlad MG / MGL deposits are applied from our range of Envirozin and Kenlevel zinc electroplating processes.

These are formulated to provide uniform, bright and ductile zinc deposits that rapidly achieve minimum thickness for optimum coverage.

ZinKlad 250 zinc systems are completed with the application of a high build trivalent TriPass ELV passivate followed by a specialist topcoat layer.

  • ZinKlad MG utilizes a unique sealer/topcoat capable of producing an insulating layer between the two dissimilar metals.
  • ZinKlad MGL offers the same corrosion performance and galvanic protection, whilst incorporating an integral lubricant into the finish,
    (COF of 0.09 – 0.14 per VDA 235 – 101 ).

Minimum corrosion performance as plated for 8 micron coating, measured against salt spray ASTM B117:

FWR    120 h (barrel) - 240 h (rack)
FRR     384 h (barrel) - 720 h (rack)

"part geometry, substrate quality and post plate handling can have an effect on finish performance"
