Three grades, one supplier
Pick the grade that matches your application.
Each grade has a defined particle window, particle shape and use case. Select against your formulation and we will supply the matching catalogue grade.
GRADE 01 / SUPERFINE/01
Superfine (2 to 4 µm)
Total Zn ≥ 99.0% typicalMost-used grade
Standard, homogeneous, micronized zinc powder with spherical particles. Designed for industrial paints, anti-corrosion coatings and electroplating. High consistency in coating processes; physical properties improve adhesion and protection of metal surfaces against environmental factors.
Typical applications
- AIndustrial paints
- BAnti-corrosion coatings
- CElectroplating
- DProtective primers
GRADE 02 / FINE/02
Fine (4 to 5 µm)
Total Zn ≥ 99.0% typicalHigh reactivity
Higher purity and slightly larger particle size than Superfine, still spherical. High active surface area and reactivity make it suitable for catalysts, pharmaceutical chemistry, chemical processes and sensitive composite manufacturing where engineering-controlled properties are required.
Typical applications
- ACatalysts
- BPharmaceutical chemistry
- CChemical processes
- DSensitive composites
GRADE 03 / FINE FLAKE/03
Fine Flake (4 to 6 µm)
Total Zn ≥ 99.0% typicalFlake shape
Innovative, specialty product produced in flake form. High purity and controlled particle size distribution, designed for coating industries, industrial anti-corrosion coatings, zinc-rich paints, and Geomet / Dacromet coating technologies. Sensitive to moisture; store in cool, dry location.
Typical applications
- AZinc-rich paints
- BGeomet and Dacromet coatings
- CIndustrial anti-corrosion coatings
- DPlating and purification

Buyer questions
What zinc dust buyers ask before the first shipment.
Superfine (2 to 4 µm) for industrial paints, anti-corrosion coatings and electroplating. Fine (4 to 5 µm) for catalysts, pharmaceutical chemistry and sensitive composites where reactivity matters. Fine Flake (4 to 6 µm) for zinc-rich paints, Geomet and Dacromet coating systems. We can recommend against your formulation if you share the application.
