Zinc oxide is highly reactive for acidity material, can effectively slowed corrosive conditions, mainly applicable for anticorrosive paint and special coating, water based coating. Has fineness particle size, light proportion, big specific surface area, strong adhesive force and covering power characteristic, can increase the function of coating, have certain screen ultraviolet radiation effect, has anti-aging effect in the coating, the conductivity of superfine zinc oxide also can give coating to antistatic behaviour, zinc oxide and zinc phosphate coordinate, can improve the anticorrosion performance of zinc phosphate.
