METASU FZ-500 A(M) / G(M)
Acid zinc brightener for high temperature bath
METASU FZ-500 is acid chloride brightener which possess low nitrogen and equal performance of ammonium – potassium bath without boric acid.
＜Merit＞
・Keeping nitrogen level as low as non-cyanide alkaline bath to meet nitrogen waste regulation
・No boric acid used to meet boron regulation
・Wide range of bath temperature. Bright quality finish will be obtained from ambient to rather high bath temperature
The merits of the following will be obtained by keeping bath temperature high
① Be able to plate without cooling bath
② No increase of plating solution surface
③ Will improve ductility, which facilitate second-workability and reduces plating flakes
④ Increase adhesion with passivate agent
・Work environment is improved. Less amount of mist and oder
