Finely dispersed TiO2, and color distribution with precision dosing, drive consistency, material efficiency, and sustainable consumption. LIQUID DISPERSED TITANIUM DIOXIDE ColorMatrix Liquid Dispersed TIO2 Dry TIO2 In the liquid form, TiO2 has dispersed into individual particles for a more homogeneous PVC dryblend. This improves TiO2 efficiency and allows use at a lower loading level.
