Description
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
Print STANDARD 7
(*) SMD or D(3,2) is the diameter of a particle having the same volume to surface area as the total volume to the total surface area of all particles.
