Hugh White orthorhombic powder, dispersion is good, high whiteness, good leveling. Has excellent lightfastness, weather resistance and acid resistance. Has good chemical inertia and moderate surface energy, so as a function of filler has good dispersibility and affinity with other media. In the powder coatings industry, particularly effective. The relative density of 4.0-4.6 do not dissolve in water, acid, alkali and other solvents, heat, acid, alkali, non-toxic, can be used for food contact products
