One of the key advantages of using anatase titanium dioxide in coatings is its superior UV resistance. This makes it ideal for outdoor applications where coatings are exposed to sunlight and other environmental factors that can degrade the finish over time. Anatase titanium dioxide helps to protect the underlying surface from UV rays, preventing fading and deterioration.

Importantly, TiO2 also has a very high refractive index (its ability to scatter light), even higher than diamond. This makes it an incredibly bright substance and an ideal material for aesthetic design use.

It is opaque and glossy, and provides bright whiteness with blue undertones.

Relative to a lot of other things that people should be concerned about, titanium dioxide in my mind, is really low on the list. I would be more worried about some substitutes that people are using for titanium dioxide that don't have decades of research associated with it, said Westerhoff.
