Improving the corrosion resistance of zinc-nickel alloy plating! Completely chrome-free surface treatment.

"RUSPERT ZERO・STAIN" is a surface treatment technology that is completely chrome-free and does not use chromate processing, serving as an alternative to stainless steel. It further enhances the corrosion resistance of zinc-nickel alloy plating. With a robust baked film, it exhibits high corrosion resistance, and by applying two thin layers, stable shielding effects and high corrosion protection can be achieved. Additionally, it maintains the appearance of zinc-nickel alloy plating while achieving a stainless steel-like finish. 【Features】 ■ Completely chrome-free treatment with minimal environmental impact ■ High corrosion resistance due to a strong baked film ■ Achieves a stainless steel-like appearance ■ No need for over-tapping ■ Can impart lubricity to the top coat *For more details, please refer to the PDF document or feel free to contact us.
