Consistent Quality from Lab to Production

At Kanto Chemicals, we offer high-purity chemicals with the same grade and quality, whether in small research quantities or bulk industrial volumes. This enables seamless continuity between R&D evaluation and production-scale application, ensuring consistent results and simplifying your workflow.

With Kanto, you can work with confidence—knowing that the chemical quality you trust in the lab is exactly what you’ll receive on the production floor.

High Purity Alkali Products – NaOH and KOH in Pellet and Liquid Form

Kanto Chemical offers a comprehensive range of alkali products, from multipurpose grades to ultra-high purity NaOH and KOH, tailored for laboratory and semiconductor-grade applications. Our products are manufactured using a proprietary alkali pelletizer, uniquely developed in-house and the only mass-production equipment of its kind in Japan.

With advanced manufacturing lines, we ensure strict quality control and consistency, enabling us to supply high-purity sodium hydroxide (NaOH) and potassium hydroxide (KOH) pellets globally. These processes are certified and operated under stringent conditions to meet the highest standards in purity and safety.

To minimize contamination, especially from heavy metals such as mercury, we employ a proprietary electrolysis purification method using ion exchange membranes for raw material processing. This enables us to produce alkali chemicals of exceptional purity.

  • Pellet-type alkali products
    Flaked alkali products are fragile and tend to produce powder, solidifying easily upon moisture absorption due to their large surface area. In contrast, our pellet-type alkali reagents have a smaller contact area, resulting in lower hygroscopicity, higher apparent specific gravity, and a more compact form. These pelletized products offer significantly better handling performance compared to the flaked type.
  • Liquid-Type Alkali Products
    In addition to the standard 48% concentration, we offer a range of liquid alkali solutions with concentrations from 10% to 40%, available in 10% increments. This lineup helps minimize the need for dilution and simplifies your preparation process.
