It has perfect metal distribution and coating power in low current and high current fields. Compared to other coating types, it is sensitive to human health and environment. The corrosion resistance of the coating made by electrolysis method is very good. Cr + 3 blue and yellow are used in the alkaline zinc plating passivation.
Advantages of alkaline zinc coating::
Homogeneous coating distribution
High corrosion resistance
Good adhesion to metal surface
Environmentally friendly (Cyanide free)
