Chrome-free zinc flake coating

Posted on 2018-08-01
  The appearance of the chrome-free zinc flake coating is matt silver gray, which is widely used in automotive fasteners and other industries, and has the following advantages:

 

  1.The coating is non-toxic and environmentally friendly

 

  2.The coating is thin,whose thickness is usually 8-10μm.

 

  3.No hydrogen embrittlement problem

 

  4.Good resistance to organic solvents

 

  5.Good heat resistance

 

  6.Corrosion resistance, long salt spray time

 

  7.Simple process

 

  The chrome-free zinc flake coating is generally applied by a conventional impregnation—centrifugation, spray or dip—drain—centrifugation coating process to obtain different coatings by adjusting the process parameters of the coating process.
