Forbrite AZ-730 2X

 

 

Forbrite AZ-730 2X is an ammonium chloride zinc plating process. It has an extraordinarily wide, bright plating range 

and can be used in either barrel or rack plating operations. The deposit is ductile, uniform and exhibits clean brilliance.

      Ⅰ. Advantages:

            1.  Less corrosion to equipments and simple treatment of effluents.

            2.  Excellent brightness and throwing power.

            3.  Good corrosion resistance.

            4.  High current efficiency and low temperature increasing.
