Alkaline Zinc-nickel Alloy Plating for Barrel Plating
1. Fast bright and high leveling and brightness ability.
2. Bright coating can be got with wide range of current density, even in low current density area can also get high brightness and leveling coating.
3. Wide operating temperature range, Good coating can be got at 10~35 ℃.
4. Particularly with high impurity tolerance, it is not easy to appear pinholes, pitting, white mist on the coating.
5. Simple operation, less brightener consumption.
6. Brightener with high stability, compatibility, and can be mixed with other brightener, transfer cylinder easily.
7. Good improvement for depressions and pinholes.
2. Formulation process and operating conditions
