Process features:
Magnesium alloy alkaline surface conditioner does not contain substances, is completely environmentally friendly, and complies with EU R regulations.
It can completely remove the oxide layer on the surface of the workpiece to obtain a freshly activated and uniform metal crystal surface, greatly shortening the film formation time of the chromium-free film and making the chromium-free film crystallize finely.
Reduce the consumption of chromium-free coating agent for magnesium alloy.
Improve the bonding strength and corrosion resistance of magnesium alloy chromium-free coating agent.
