Since its founding in 1968, Nippon Hyomen Kagaku Kabushiki Kaisha has pursued the most advanced technologies demanded by each era. Our metal surface treatments add critical value to automobiles, electronic products, precision instruments, construction materials and more.

We have continuously refined these technologies, earning customers’ highest trust and top industry acclaim—especially for our rust-preventive, zinc-electroplating process chemicals.

Our environmentally responsible trivalent-chromium “Tryner Series” is now specified by major automakers worldwide. Responding to the rise of high-performance titanium and magnesium alloys, we have developed dedicated process chemicals and expanded into wastewater-treatment agents and automated control systems, turning decades of expertise into a comprehensive consulting service.

Going forward, we will keep sharpening state-of-the-art, flexible solutions that satisfy all customers and end users.
