What is a titanium oxide? For this kind of coating material, which may be a lot of people don't know, here is the introduction to it:

Titanium oxide is a kind of chemicals, alias titanium sesquioxide, molecular weight of 143.73, CAS number 1344-54-3.

Properties: purple powder, hexagonal system structure, the lattice constant of alpha = 0.5155 nm. Oxygen containing 59.5% ~ 60.8% (at). Hydrofluoric acid soluble in 40% (mass), may be for nitric acid erosion, but not the strong hydrochloric acid, sulfuric acid erosion, also not as strong alkali erosion, and 30% (mass), hydrogen peroxide solution to generate yellowish solution. Heating in 250 ~ 300 ℃ in air into five titanium oxide. Vacuum in the 1600 ℃ heating mixture of titanium powder and titanium dioxide or 1500 ℃ hydrogen reduction preparation of titanium dioxide. The titanium ion itself is a kind of excellent reductant.

Titanium oxide widely used in coatings, plastics, paper, printing inks, chemical fiber, rubber, cosmetics and other industries. It has a high melting point and is also used to make fire-resistant glass, glaze, concrete, clay, and high temperature resistant experimental vessels.

At the same time, titanium oxide has a good UV masking effect, and is often incorporated into textile fibers as a sunscreen. Ultrafine titanium dioxide powder is also added to sunscreen cream to make sunscreen cosmetics.
