The coating industry has high requirements for titanium dioxide in paint and coating formulations. As an inorganic white pigment, titanium dioxide has excellent properties in terms of whiteness, chemical stability, weather resistance, opacity, hiding power, gloss, dispersibility, and processability, etc. Therefore, titanium dioxide is applied widely as a white pigment in paint formulations.At present, 60% of the total titanium dioxide are used in the coating industry. The amount of titanium dioxide accounts for 10% to 35% of the total coating. Titanium Dioxide are used in lots of applications such as water-based coatings, coil coatings, latex paint (architectural coatings), powder coatings, automotive paints, and solvent coatings, etc.
