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.
