What protective effect can dacromet play?

Posted on 2019-08-14
The car has now become an ordinary daily vehicle. Regular car maintenance can effectively extend the service life of the car. The protection of the car accessories depends on the Dacromet coating. Most of the car accessories are sent to professional manufacturers. Dacromet coating is used to improve the overall safety performance and use of the car. Next, let's take a look at the protection of Dacromet coating. Let's take a look.

 

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.
