Forbrite CZ-725 conc.

　

               Forbrite CZ-725 conc. is an ultra high performance additive for cyanide zinc plating baths.

   The use of Forbrite CZ-725 conc. results in more brighteness in low current density areas.

           Furthermore, deposits are ductile and very receptive to any type of post-plate treatment.

Ⅰ. Characteristics：

    1.   Excellent brightness in low current density areas allowing trouble free plating of irregular shape.

    2.   Deposits are very receptive to any type of post-plate treatment.

    3.   Tolerant to high operating temperature.

    4.   More tolerant to high carbonate concentrations than competitive.
