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.
