What is Titanium dioxide?
Titanium dioxide (CAS 1317-80-2), or TiO2, is a white pigment and UV-blocking agent.
Where is Titanium dioxide used?
- Coatings: hiding power and durability in architectural and industrial paints and primers
- Plastics: opacity and UV stabilization in films, pipes, and packaging
- Personal care: sunscreens
- Color cosmetics: physical UV filter and white pigment
- Paper and textile manufacturing: brightness and opacity in paper coatings and synthetic fiber delusterants
- The rutile form dominates commercial supply.
Good to know: Rutile grades account for most industrial demand; surface-treated grades with alumina, silica, or organic treatments are standard for coatings and plastics, while uncoated grades serve specialty uses.
Commercial specifications
- Whiteness index, particle size, and surface treatment are key procurement criteria
