Titanium Dioxide (TiO₂): Rutile vs Anatase — Which Grade for Your Industry?
Why Titanium Dioxide Matters
Titanium Dioxide (TiO₂) is the benchmark white pigment worldwide, prized for its exceptional opacity, brightness and UV stability. Two primary crystal forms exist — Rutile and Anatase — each with distinct properties suited to different applications.
Rutile Grade TiO₂
Rutile is the more stable crystal form with superior opacity and weather resistance. Key properties: Refractive index 2.71, excellent UV stability, high hiding power, suitable for outdoor applications. Used in: exterior paints and coatings, PVC pipes and profiles, masterbatch for plastics, printing inks.
Anatase Grade TiO₂
Anatase has a lower refractive index (2.52) but offers a brighter blue-white tone. Preferred for: interior paints where brightness is critical, paper laminates and coatings, fibre and textiles, cosmetics and sunscreen formulations.
Specification Comparison
When sourcing TiO₂, key specifications include: TiO₂ content (≥98%), whiteness/brightness (≥98 ISO), tinting strength, oil absorption and pH. Trident Chemicals supplies both grades with full technical data sheets and COA documentation.
Global Market Trends
TiO₂ demand is growing at 4-5% annually, driven by the paint and construction boom across Asia, Africa and the Middle East. India has emerged as a competitive export hub for mid-range TiO₂ grades serving GCC and African markets.
