JW-530 Brightening Agent for Cyanide Zinc Plating
Category:
Detailed description:
01
The coating is uniform and the surface is mirror‑bright, making it suitable for various passivation processes.
02
Uniform plating is achieved in both hanging and barrel plating. This process yields a bright, white‑bright finish that can be directly passivated, eliminating the need for brightening; it is particularly well suited to the requirements of barrel plating.
03
Fast deposition rate, excellent coverage, and minimal scorching in high‑current areas.
04
Aldehyde-free, excellent temperature stability, and low consumption.
