The ZH-558 copper blackening agent process effectively reduces the reflectivity of copper surfaces while maintaining good electrical conductivity.
It is a single-solution chemical with simple control and easy operation.
It offers good conductivity with minimal impact on resistance and small Moiré interference patterns at high pixel densities.
Compared to the traditional palladium sulfate system, it significantly reduces costs.
It is widely used in electronic touchscreens for Samsung, Apple, Dell, and other brands.
