When it comes to the word weatherability, it may not be well understood by everyone. In fact, weather resistance refers to the ability of titanium dioxide pigment to resist ultraviolet rays when it is filled with the base material under the presence of both oxygen and moisture. If titanium dioxide and similar products have poor weather resistance, they will lose gloss, chalk, fade, and become brittle after being left in the air for a period of time. In addition, the adhesion, water permeability, and abrasion resistance of titanium dioxide will also decrease. Therefore, the photochemistry of titanium dioxide is the main reason that affects the weather resistance of the coating film.
Rutile titanium dioxide has a small and compact unit lattice, high refractive index, good optical performance, large dielectric constant, and low thermal conductivity. It is mainly used in coatings, plastics, inks and other fields.
