Zinc powder

Superfine zinc powder is mainly used as key raw material in zinc-rich coating,etc.

Zinc powder:

1. PropertiesChemical name:metal zinc Molecular formula:Zn Molecular weight:65.38 Appearance: light gray spherical powder Density:7.14g/cm3

2. Chemical properties Insoluble in water, soluble in acid and alkali. It is a kind of strong reducer, easy to react with acid & alkali, and give out hydrogen at the same time. It will become block in wet air

3. Uses material of paint, coating and chemicals, reductant of organic synthesis, or used in metallurgy, pesticide, dye and drugs.
