MX-RN21 Barrel Nickel Plating Additive
Features:
1. The plating is extremely pure white,
bright.
2. The plating solution has good
dispersion, evenly thickness, great coverage over low
potential area.
3. Quick bright dipping speed, leveling plating.
4. Low stress, good ductility, after
plating it can be formed by bending or stamping.
5 High concentrate and low consumption,
high toleration to the impurities, easy maintenance and use.
