Titanium dioxide (TiO₂) is the essential white pigment in coatings, available in two main crystal forms: Anatase and Rutile.
Rutile TiO₂ is predominant due to its higher refractive index, superior opacity, and excellent weather resistance, making it ideal for exterior and high-performance paints.
Anatase TiO₂, with softer texture and higher brightness, is often used in interior applications where extreme durability is less critical. Both types provide critical hiding power, brightness, and UV protection to coating systems.
