Zinc Powder / Zinc Dust

Zinc Powder, dark gray powdered metal zinc, insoluble in water, can dissolve in acid and alkali, slowly soluble in acetic acid and ammonia. It has strong reducibility.

Product Details

Zinc powder has a strong reducibility and hydrogen is released with acid and alkali.

It mostly used as anti-corrosion pigment in industrial coating. These metallic zinc pigments act as active preservatives and form a coating on the metal surface to protect the structure of the building.

Zinc powder also acts as a reducing agent and catalyst in various chemical reactions.
