Zinc Dust
- Molecular Formula
- Usage: Zn (Pigment for anti-corrosion paint for containers, ships and steel structures /Reducing agent in organic chemistry)
- Hanchang is strengthening its position as the leading manufacturer of zinc dust in Korea with its largest production capacity and accumulated technical experiences. Hanchang’s zinc dust, produced with Hanchang’s unique process, exhibits high anti-corrosion property due to its high metal contents and consistent particle size distribution. The quality of Hanchang’s zinc dust is assured with newest analysis equipments.
● Characteristics and Capacity
Color & Shape: Gray powder
Corrosion of a metal surface is due to its reaction with surrounding oxidants, such as air, water and carbon dioxide. A zinc dust layer physically prevents the contact of oxidants with the steel surface. Also, since zinc has higher ionization tendency than iron, the penetrated oxidants react with zinc rather than iron.
Production Capacity: 1,200 MT/month
