item no.HN-CS200

2.Bath Composition and Working Conditions,

(1).Bath Composition
Make-up agent HN-NC1               250~500ml/L
Additive agent HN-NC2                80~120ml/L
Modifying agent HN-NC3              40~80ml/L
Potassium carbonate(CP Grade)          30~50g/L
(2).Working Conditions,

pH value                             9.2~10
Temperature                          55~65°C
Cathode current density (rack plating)      0.5~2.7 A/dm2
Cathode current density(barrel plating)     0.2~0.9 A/dm2
Anode                           anaerobic electrolytic copper(>99.5%)
Inert anode                    high purity graphite or stainless steel 304/316
Filtration                          high-capacity circular filtration
Agitation                            strong air agitation
(3).Consumption:
Make-up agent HN-NC1    Enriched liquid, which is used for supplement or making-up. It also contains other balance element of bath.
Additive agent HN-NC2    Usual single supplement, which is used as the accelerating agent and chelating agent for dissolution of anode copper. The consumption of HN-NC2 is 470-940ml/1000Ah.
Modifying agent HN-NC3   It is used as the adjuster and buffer of the bath's pH value

3.Application and Advantage,

1. It can be used in direct copper plating on steel, copper and zinc alloy as the replacement of cyanide copper plating process. 
2. The plating layer is clear and has good combining power; subsequently, acid copper and bright nickel can be plated on the layers.
3. The bath solution is of excellent dispersing ability .It can be used in rack plating and barrel plating.
4. The bath solution is stable, easily controlled and maintenance.
