Intro：
When it comes to achieving brilliant whiteness, maximum opacity, and long-lasting durability, Rutile Titanium Dioxide (TiO₂) remains the undisputed king of white pigments. With its superior refractive index and excellent UV resistance, Rutile TiO₂ is the backbone of high-end paints, coatings, plastics, and inks. At WSD Chemical, we supply premium-grade Rutile TiO₂, engineered to deliver unmatched hiding power and weather resistance for your most demanding applications.
Rutile is one of the three naturally occurring forms of titanium dioxide (alongside anatase and brookite), but it is the most stable and widely used in industrial applications due to its crystal structure.
Highest Refractive Index: Rutile TiO₂ boasts the highest refractive index (~2.7) among white pigments, providing exceptional light scattering capabilities and superior hiding power.
Outstanding Weather Resistance: Unlike Anatase, Rutile grades offer excellent UV light resistance, preventing chalking and discoloration in outdoor applications.
Chemical Inertness: Highly resistant to acids, alkalis, and chemical corrosion, ensuring color stability in harsh environments.
Surface Treatment Technology: Our grades feature advanced silica/alumina surface treatments to enhance dispersibility and durability.

Rutile TiO₂ is the go-to pigment wherever brightness, opacity, and longevity are required:
Paints & Coatings: The dominant application. Used in architectural paints, industrial coatings, powder coatings, and automotive finishes for superior gloss and weather resistance.
Plastics & Masterbatches: Provides bright whiteness and opacity in PVC pipes, profiles, films, and engineering plastics while protecting polymers from UV degradation.
Inks: Essential for high-opacity white printing inks, especially in packaging and lamination.
Paper & Rubber: Used as a filler and whitening agent to improve brightness and printability.
Choosing the right TiO₂ supplier is critical to maintaining consistent product quality. WSD Chemical ensures:
✔ High Purity & Brightness: Our Rutile grades consistently achieve high L* values (whiteness) and low yellowness indices.
✔ Optimal Dispersion: Treated for easy wetting and dispersion, reducing grinding time and preventing agglomeration in your formulations.
✔ Strict Quality Control: Every batch is tested for fineness, oil absorption, and tinting strength to ensure compliance with global standards.
✔ Reliable Global Supply: Stable inventory and efficient logistics support for large-scale B2B procurement.

Q: What is the main difference between Rutile and Anatase TiO₂?
A: Rutile has a tighter crystal structure, making it harder, denser, and more chemically stable than Anatase. Crucially, Rutile offers far superior UV resistance and weathering properties, making it ideal for outdoor applications, whereas Anatase is typically used for indoor paints or paper applications.
Q: What does "surface treatment" mean for TiO₂?
A: Surface treatment involves coating the TiO₂ particles with inorganic (silica, alumina) or organic compounds. This improves the pigment's dispersibility in different mediums (water vs. solvent), enhances weather resistance, and prevents catalytic degradation of the base material.
Q: How do I choose the right Rutile grade for my application?
A: It depends on your medium. Water-based paints require hydrophilic surface treatments, while plastics require grades treated for compatibility with polyolefins or PVC. Our experts at WSD Chemical can recommend the optimal grade based on your specific formula.
