Sulfur-free semi-bright nickel FS100 can produce a smooth and soft nickel layer with high leveling and moderate brightness, making it an ideal base layer for multi-layer nickel plating. Its sulfur-free chemical properties directly affect the stability of the base metal, making it suitable for multi-layer nickel plating of copper, brass, steel, and zinc alloys. The coating has good uniformity, strong leveling ability, and provides satisfactory corrosion resistance. The potential difference generally exceeds 125mv and can even reach 140mv.
