Zinc Powder

Description

Zinc powder (zinc metallic pigment) is a gray metallic fine powder with strong reducing and binding capacity. It remains stable in dry atmosphere but tends to accumulate in moist air leading to the formation of alkali carbonate on the particle surface.

Functions

Zinc metallic pigment is mainly used as a primary raw material for galvanizing coatings, as well as for anti-corrosion protection and other high-performance coatings. They can be widely used in large metal structures, shipbuilding, aviation, automotive industry. Ordinary zinc powder can be widely used in metallurgy, engineering chemistry, pharmaceuticals, pigments, batteries and other fields.

Packaging

Packed in iron buckets with 2 polyethylene bags of 25 kg each in each bucket, or according to customer requirements.

Transport & Storage

Store in a dry, ventilated warehouse without the presence of acids, alkalis and flammable substances. During storage and transportation, avoid moisture, water and ignition.
