Titanium Dioxide - TiO2 Pigment for Paint, Coatings & Inks
Titanium dioxide (TiO 2) is by far the most suited white pigment to obtain whiteness and hiding power in coatings, inks and plastics. This is because it has an extremely high refractive index and it does not absorb visible light. TiO 2 is also readily available as particles with the right size (d ≈ 280 nm) and the right shape (more or less spherical) as well as with a variety of post-treatments.
