Foshan Renchang Chemical Co., Ltd., Guangdong Province

Process Features:
The Pearl River Delta magnesium alloy acid microetchant removes the oxide film, oil film and impurities on the surface of the workpiece to form a uniform and clean layer of magnesium alloy surface, which is conducive to the formation of good bonding force in subsequent processes. It can completely remove the oxide layer on the surface of the workpiece to obtain a freshly activated and uniform metal crystal surface.
No excessive corrosion of the magnesium alloy matrix.
Improve the bonding strength and corrosion resistance of magnesium alloy coating agents.
