1. Passivation: Metal oxides due to passivation slow down the corrosion reaction rate of zinc and steel;
2. Electrochemical action: The zinc layer is corroded as a sacrificial anode to protect it;
3. Barrier protection: The treated layer of zinc flakes and aluminum flakes provide an excellent barrier between the steel substrate and the corrosive medium, preventing the corrosive medium and the depolarizing agent from reaching the substrate;
4. Self-recovery: When the coating is damaged, zinc oxides and carbonates move to the damaged area of the coating, actively recovering the coating and restoring the protective barrier.
The above is the four aspects of protection for Dacromet coating. After you understand it, you can also see the effect of Dacromet paint, which is why people nowadays use Dacromet paint widely.
