As the global market leader of Fine Zinc Powder (formerly named zinc dust) with a production capacity of 100.000 tons per year, we developed three unique production process (Atomization, Larvik & Muffle), allowing us to offer the widest range of products. Our Fine Zinc Powder, mostly used as anti-corrosion pigment in industrial coatings or as reducing agent and catalyst in various chemical reactions, is continuously improved to fit our customers’ and markets’ expectations. That’s why we developed new products such as alloyed powders (bismuth, aluminum, magnesium) or 0G, a zero gassing powder for use in 1-K and 2-K water-based anti-corrosion paint. Sustainability-oriented, EverZinc has also improved its recycling technology and is now producing more than 30% of zinc metal pigment from zinc secondaries.
Applications & Uses

- Applications
Fine Zinc Powder is also important in chemical reactions and is used in various kinds of organic reactions such as Cyclopronation, the [2+2]-Cycloaddition, the Clemensen reduction, the Dehalogenation of tribromothiophenes, the Azo-coupling or the Production of organozinc halides. In terms of applications, these reactions are important for life science applications (as fine zinc powder acts as the reagent for the synthesis of organozinc compounds), for the recovery of precious (eg. gold and silver) and platinum group metals (as produced in the Merrill Crowe Process) or in the purification process of leach solutions for the zinc metal production. Another very important use of fine zinc powder is its catalyst role in the production of Sodium Hydrosulphite, which is mainly used in three sectors:
- Paper industry: bleaching of mechanical pulp, de-inked pulp and kaolin clay
- Textiles: reducing vat dyes (indigo), decolourising dyes, bleaching fibers, yarn and fabrics
- Specialist chemicals: a powerful reducing agent used in the chemical and pharmaceutical industries, metals and antioxidants.
