Zinc Dust (CAS 7440-66-6) is a fine metallic zinc powder with a gray, metallic appearance and a high reactive surface area, typically containing 98% zinc, and it serves as the primary pigment in zinc-rich anti-corrosion primers and as a reducing agent in chemical and metallurgical processing. The product typically features a Zinc Content of 98% , making it the primary component in zinc-rich anti-corrosion primers. Its controlled Particle Size Distribution ensures high-density packing in coatings for superior cathodic protection. In the chemical and metallurgical industries, it acts as a powerful Reducing Agent for the purification of solutions and the precipitation of metals. It is a critical material for the Galvanizing Industry and battery technologies.
Zinc Dust
Applications
- Anti-Corrosive Coatings: Key pigment in zinc-rich paints and primers used to protect infrastructure and marine vessels from rust.
