METASU FZ-77A (T) / FZ-77GC (T)
Zinc plating brightener for high temperature acid bath
The prevention of greenhouse effect caused by carbon dioxide produced from system that derives energy from burning fossil fuels, and reduction of industrial waste materials have become worldwide issues. METASU FZ-77, a zinc plating brightener for high temperature acid bath, can be said to have been developed to mitigate these issues. By making it possible to be used at high bath temperature (30 to 45℃), electric power required for cooling is reduced leading to an energy-efficient system and lower electricity costs. Industrial waste material is reduced since the increase of plating solutions due to cooling is prevented.
• Suitable for a wide number of plating bath, an attractive shiny plated film can be obtained
However, an operating range of 30 - 45℃ is recommended, for the brightener to display its
A plating bath with a higher temperature has the following merits.
①Processing can continue without having to cool down the plating solution.
②) There will be no increase in the amount of plating solution used.
③Productivity is improved due to a higher electrical conductivity during plating.
④Physical aspects of plated film is improved with excellent properties for secondary
⑤Chromate adhesion improves.
• Usable for all ammonium bath and ammonium-potassium (1:1 ratio) bath
• Working environment is improved due to reduced mist and odor.
