Zinc oxide are zinc oxide ZnO with hexagonal structure with the size of the primary acicular particles 0,1 -1,0 μm, of which sometimes formed fused star-shaped particles. Can be colloidal particles of rounded shape with a size of 0.01 μm. Optimal optical particle size of 0.48-0.50 μm. With the decrease in particle size improves tint reducing power and hiding power of the pigment, but it increases photoactivity and weather resistance deteriorates, so almost for coatings prefer an acicular particle size of 0.5 to 1.0 μm.
Zinc oxide is widely used for many types of paint and varnish materials for coatings, which are operated indoors. A large number (50%) highly dispersed chemically active zinc oxide is used in rubber industry.
