Description

1. Characteristics,
Cyanide Free, environmental friendly
It can achieve elegant and bright zinc plating over a wide range of current density
Extremely even plating thickness, with high dispersion capacity
Plating is extremely soft and easy to chromate passivation, the deformation process can be processed after plating
Process stability, high tolerance for impurities and good temperature resistance
Plating solution is simple and stable, without any control hassle
Suitable for hanging galvanized and roll galvanized production line

3. Additive function and complementary,
1) Polish agent HN-NK1: Fine crystalline plating can be achieved over a wide range of current density. Insufficient amount can result in low potential zone with lightless and a small amount of gray fog, in case of excessive, cathode hydrogen evolution severe and result in low current efficiency.
2) Additive HN-NK2: The Plating can improve brightness and leveling, prevent white Plating in a high potential zone. Insufficient amount can result in Less brightness in middle potential zonet, and whitish in high potential zone; While excessive can result in cathode hydrogen evolution severe, and low current efficiency.
3) Impurity agent HN-NK3: Special anti-hard water and Metal impurity agent, the water can complex Ca, Mg and other metal impurities, Thereby reduce the impact of metal impurities contamination
