To verify the applicability of various types of zinc-rich coating standards and salt spray resistance
Time of Update: 2020-12-10
Appendix E "Technical Conditions for Inorganic Zinc-Rich Anti-Slip Coatings for Railway Steel Bridges" stipulates that the zinc-rich primer needs to pass the 500 h salt spray test under conditions of 80±5) μ m of paint film thickness, and the surface of the model is free of foam and red rust.

Is the zinc content in zinc-rich primers important for corrosion resistance?
Time of Update: 2020-11-26
Zinc content in zinc-rich primer is low, because zinc powder particles can not form a complete zinc powder layer, zinc cathode protection effect is not obvious, salt spray test will soon appear rust, but due to low zinc content, resin content will increase accordingly, its salt water resistance is better.
