Supplement:
HN-2700A and HN-2700 are used as make-up solution, HN-2700A and HN-2700C are used as supplement. When Ni content is increased by 1g/L, 13.3ml/L of HN-2700A and 20ml/L of HN-2700C are needed to be replenished. First add HN-2700C, and then replenish HN-2700A, and thereafter adjust PH value with ammonia.

Application and Advantage
1. The deposit is of high ductility and has good cohesion on different workpieces.
2. Unique additive system and high tolerance against metal impurities can prolong the working life of the bath.
3. Stable bath solution which is easy to control.
4. The additive can be replenished under working temperature.
5. It is suitable for both rack and barrel plating.
