Titanium dioxide (TiO 2) is the white pigment used to give whiteness and hiding power, also called opacity, to coatings, inks, and plastics. The reason for this is two-fold: TiO 2 particles of the right size scatter visible light, having wavelength λ ≈ 380 - 700 nm, effectively because TiO 2 has a high refractive index.Web

Titanium dioxide powders are wetted out right within the rotor/stator assembly where vigorous mixing takes place. Dispersion is virtually instantaneous. At the same time, rapid product turnover helps to keep solids uniformly suspended in the slurry. Most formulas include a dispersant to prevent settling long after the mixing step.Web
