AL 200 Aluminum And Aluminum Alloy Chromium-free Passivator

AL 200 Aluminum And Aluminum Alloy Chromium-free Passivator

 

Features

AL200 is suitable for passivation treatment of aluminum, which can form a titanium-zirconium composite conversion film on aluminum substrate and has good corrosion resistance.

 

- Nickel-free and chromium-free process;

- It can be used for pretreatment of liquid coating, powder coating, sizing, etc., and can replace trivalent chromium or hexavalent chromium processes;

- Passivation speed is fast, and it is not easy discoloring;

- Used for pretreatment of painting: greatly improve the binding force of printing or painting.

The film layer is colorless and transparent, which does not affect the appearance of the workpiece.
