Zinc is an important industrial raw materials,
widely used in chemical dyes, metallurgy, zinc,
paint coatings and pharmaceutical industries.
One of the most extensive market epoxy zinc-rich
primer paint industry in the amount of zinc
powder 40 to 70 percent, mainly used in sea
water, fresh water and the atmosphere in the
media of anti-corrosion metal surface treatment. |
