HN-82 High speed decorative chromium plating solutions
2 components: Make up solution HN-82, replenisher HN-83
1) Adopt solubility and mixed catalyst, easy to operate. 2) It has higher current efficiency of cathode and deposition velocity, can operate under high current density. 3) The components can be activated well with wide brightening range.
4) High tolerance against impurities. 5) Excellent covering power and dispersive ability. 6) Suitable for all kinds of chrome plating components which is high required in carrying power.
