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.
