METASU FZ-77M2 (T) / ZB-627G (T)

Zinc plating brightener for high-speed high-concentration chloride bath

The METASU FZ-77M2 is the first of its kind, high-speed zinc plating bath process to achieve a plating speed of 3μm/minute.
It has wide coverage from high-speed zinc plating to moderate speed plating for cast iron.

• High-speed plating process of 3um/min.
• In-line processing of zinc plating becomes possible.
• Typical issues of high-speed plating such as high zinc concentrations and decomposition of

  the brightener are resolved.
• By resolving the brightener decomposition issue, continuous usage of a stable plating solution

  becomes possible.
