Main Characteristics:
Nano-zinc powder, ultra-fine zinc powder prepared through a special process, the high activity of zinc
powder has a high content of zinc and other impurity elements on the particle surface smooth, large
surface area and average particle size controlled, bulk density surface oxidation, melt deformation and
adhesion to a little grape-like particles, easily dispersed and industrial applications.
Usage:
Mainly used as key raw material in zinc-rich coating,as well as in anti-corrosion, environment protection
and other high performance coating. They can be widely applied in large steel structures, ship building,
container industries aviation, automobile; also widely applied in chemical industry,Mechanical
Galvanizing,Metallurgy and Medicine Area.
Storage:
Stored in dry, airy warehouse without acid, alkali and inflammables. Be cautious of moisture,
water and fire during storing and transportation.
