Surface treatment technology "RUSPERT ZERO・STAIN"
Completely chrome-free! Treatment that takes into account the global environment without relying on hexavalent chromium, of course, and trivalent chromium.
"RUSPERT ZERO・STAIN" is a revolutionary surface treatment technology that enhances the corrosion resistance of zinc-nickel alloy plating, designed as a complete chrome-free specification without chromate treatment, serving as an alternative to stainless steel. By forming a thin baked film on a uniform zinc-nickel alloy plating layer, the fitting of fastening components such as bolts and nuts becomes smoother, eliminating the need for over-tapping. The robust baked film exhibits high corrosion resistance. By applying two thin layers, stable shielding effects and high corrosion protection can be achieved. 【Features】 ■ Environmentally friendly ■ High corrosion resistance ■ Lubricity ■ Fit ■ Appearance *For more details, please download the PDF or feel free to contact us.
