Rutile vs Anatase Titanium Dioxide
Titanium dioxide pigments are produced in two primary crystal structures:
| Type | Characteristics | Typical Applications |
|---|---|---|
| Rutile Titanium Dioxide | Higher opacity, excellent UV resistance | Paints, coatings, plastics, construction materials |
| Anatase Titanium Dioxide | Higher brightness, lower abrasion | Paper, inks, fibers |
Most construction and coating industries buy rutile titanium dioxide because it provides superior durability and weather resistance.
Manufacturers frequently buy titanium dioxide to improve the performance and appearance of paints, cement products, coatings, sealants, plastics, and decorative building materials. Because of its high refractive index and outstanding dispersion properties, titanium dioxide enhances the opacity, brightness, and durability of finished products.
