Positioning

Uses a chromium-free environmentally friendly formula to construct a uniform and dense conversion film on the aluminum surface through chemical reaction. This passivation film significantly improves the salt-spray resistance and rust prevention level of aluminum alloys, while serving as an excellent base for organic coatings, enhancing spray coating adhesion by one grade. Suitable for functional protection of aluminum profiles, die-cast parts, and aluminum castings in demanding environments.

Features

• Green and eco-friendly: Contains absolutely no chromium ions or heavy metals, passing the world's highest-level RoHS and REACH testing.
• Excellent coating adhesion: The protective film formed on the aluminum surface not only provides strong bare-film corrosion resistance but also forms powerful chemical bonds with spray coating, powder coating, and baked paint layers, thoroughly eliminating risks of coating blistering and peeling.
