Zinc Dust

Zinc Dust is a pure metal powder manufactured by distillation process. It is suitable for Zinc Rich Primer (e.g. Ethyl Zinc Silicate and Epoxy Primer). Zinc dust is graded by average particle size.
Grades of Zinc Dust:
USES: Paints, Pharmaceuticals, Catalyst, Jewellary, Mechanical plating, Zinc related product.
PACKING: 50 KGS. Drum
