What is Atso Tek Zinc Dust
A controlled metallic powder, not a generic commodity.
Our zinc dust is atomised metallic zinc with tightly controlled particle distribution and minimal impurity load. Each lot is sized to a defined D10 / D50 / D90, characterised for zinc oxide content, and shipped against a written Certificate of Analysis. That is the difference between a paint that protects for fifteen years and one that fails inspection in the second.

Three grades, one supplier
Pick the grade that matches your application.
We don't push a single specification on every customer. We supply three distinct grades and help you select the one that fits your formulation, your QC standard, and your unit economics.
GRADE 01 / STANDARD/01
Standard Zinc Dust
98.5 to 99% ZnBest price per ton
Balanced particle distribution for general purpose anti corrosion paints, hot dip galvanizing flux and basic chemical reactions. The workhorse grade for structural steel primers and metal protection at scale.
Typical applications
- AGeneral industrial coatings
- BHot dip galvanizing flux
- CStructural steel primers
- DBasic zinc chemistry
GRADE 02 / HIGH PURITY/02
High Purity Zinc Dust
99.5 to 99.8% ZnMost requested grade
Minimal lead, cadmium, iron and copper impurities with consistent particle sizing. Specified by marine coating houses, automotive primer plants and pharmaceutical intermediate producers where impurity tolerance is tight.
Typical applications
- AMarine zinc rich primers
- BAutomotive OEM coatings
- CPharmaceutical intermediates
- DPremium metallurgical use
GRADE 03 / ULTRA FINE/03
Ultra Fine Zinc Dust
Custom · submicronSpecialty / R&D
Submicron particle size with custom specification for advanced batteries, conductive coatings and nanomaterial R&D. Pilot batches available for formulation development before scaling to commercial tonnage.
Typical applications
- ALithium and zinc air batteries
- BConductive coatings
- CSpecialty catalysts
- DNanomaterial research

Where our zinc dust ships
Four sectors. Hundreds of formulations. One supply chain.
From galvanizing lines to gold leach circuits, the same lot of zinc dust has to behave differently in every customer's process. We help you choose the grade that performs.
/02Zinc Dust
ZRP / Marine
Anti corrosion coatings
Zinc rich primers (ZRP) for marine, oil and gas, infrastructure and bridge protection. High Purity grade for ISO 12944 systems and marine specs.
/03Zinc Dust
Merrill Crowe
Gold recovery
Merrill Crowe zinc precipitation in cyanide leach circuits. Particle size and purity directly drive gold cementation efficiency and tailings loss.
/04Zinc Dust
Specialty / R&D
Specialty chemistry
Pharmaceutical intermediates, conductive coatings, advanced batteries and laboratory grade zinc reductions. Ultra Fine grade engineered to spec.
Compliance and documentation

Buyer questions
What zinc dust buyers ask before the first shipment.
Standard grade (98.5 to 99% Zn) is usually the right fit for galvanizing flux, both economically and technically. We can match a specific D50 window if your line has a tight residue spec.
