  • Applications

    Titanium Dioxide (CAS 13463-67-7) is widely used as a white pigment and opacifying agent in paints and coatings, plastics, and paper to boost hiding power, brightness, and whiteness. In the plastics and polymer sector, it helps improve color stability and UV resistance, while increasing product brightness. In cosmetics and personal care, Titanium Dioxide serves as a colorant and a UV filter, contributing to product stability and sun protection. In inks and coatings, it enhances opacity and brightness of formulations. For specialty applications, TiO2 such as anatase or rutile grades are used for photocatalytic and self-cleaning surfaces, enabling light-driven oxidation of contaminants. It can also act as a filler and brightness enhancer in paper and other industrial formulations, subject to grade and regional regulations.
