Can also be used as a coating substrate! It can improve the corrosion resistance, which is the biggest weakness of Mg.
"Magnesium conversion treatment" is a process that chemically creates a passive film on the surface of magnesium, which is highly susceptible to corrosion, in order to improve its corrosion resistance. Traditionally, treatments using chromic acid were employed, but in response to environmental concerns, we have adopted a conversion treatment that does not use chromic acid. At Sun Industry, we perform manganese phosphate conversion treatment for the surface preparation of industrial robot painting, and oxalic acid-based treatment to enhance the adhesion of liquid crystal housing components. We also conduct conversion treatments that result in a black appearance. [Features] ■ Improves the corrosion resistance, which is the greatest weakness of Mg ■ Confirmed no white rust formation after 8 hours in salt spray tests conducted in-house ■ Enhances paint adhesion through the treatment ■ Can also be utilized as a paint base ■ Further improves corrosion resistance when painted ● For more details, please visit our company website and contact us.
