What is Titanium Dioxide CAS 13463-67-7?

Titanium Dioxide CAS 13463-67-7 is a white inorganic pigment with the formula TiO2 and molecular weight 79.87 g/mol. It is produced in rutile and anatase crystal forms and is widely used for opacity, whiteness and UV protection.

What is the difference between rutile and anatase TiO2?

Rutile has a denser crystal structure, higher refractive index and better exterior durability, making it the usual choice for outdoor coatings and plastics. Anatase is softer, has a lower refractive index and can give a brighter bluish-white tone in interior paints, paper and fibers.

Why is TiO2 used as a pigment and opacifier?

Its high refractive index gives strong light scattering, which provides hiding power and opacity at relatively low loading. This makes it effective in paints, coatings, plastics, rubber, paper, inks and other bright-white or tinted formulations.

How does surface treatment affect Titanium Dioxide performance?

Surface treatments can improve dispersion, wetting, compatibility and storage stability in water-based or solvent-based systems. Treated rutile grades are often designed for exterior applications where gloss retention and chalk resistance are important.

Which grade should be selected for an exterior coating?

A treated rutile grade is generally preferred for exterior architectural or industrial coatings because it offers higher opacity, UV resistance, weatherability and resistance to chalking. Grade selection should also consider resin type, sheen and application conditions.

Titanium Dioxide CAS 13463-67-7

Titanium Dioxide (CAS 13463-67-7) is the premier white inorganic pigment utilized globally for its exceptional refractive index, brightness, and opacity in coatings and plastics. Chemically identified as Titanium(IV) oxide, this fine white powder acts to scatter visible light effectively, providing superior "hiding power" and whiteness to end products. Available commercially in two primary crystal forms—Rutile (for weatherability) and Anatase (for whiteness in paper/fibers)—it is extensively integrated into architectural paints, PVC profiles, printing inks, and masterbatches. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing (via both Chloride and Sulfate processes) and customized specifications to meet specific dispersion and oil absorption requirements. Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

Product Description

Titanium Dioxide (TiO2) is a white inorganic pigment known for its exceptional brightness and very high refractive index. It is produced through advanced chemical processes (Sulphate or Chloride process) to ensure high purity and consistent quality. Our Titanium Dioxide features excellent pigment properties such as high hiding power, strong tinting strength, superior whiteness, and weather resistance. It disperses easily in both water-based and solvent-based systems. It acts as a vital white pigment widely used in coatings, plastics, and paper industries to provide opacity and durability to the end products.

Applications

Titanium Dioxide is one of the most versatile white pigments used globally:

Paints & Coatings:
- Used in interior and exterior architectural coatings, industrial finishes, and powder coatings.
- Provides high opacity, brightness, and protects the substrate from UV degradation.
Plastics & Masterbatches:
- Widely used in PVC, polyolefins, and engineering plastics.
- Ensures excellent heat resistance and light fastness in plastic products without affecting the material’s mechanical properties.
Paper Industry:
- Used as a filler in paper pulp to enhance brightness, opacity, and printability of high-grade paper.
Inks:
- Essential for solvent-based and water-based printing inks to ensure vivid colors and coverage.
Rubber & Others:
- Used in rubber manufacturing (tires, shoe soles) and ceramics.

Storage Conditions

Environment: Store in a cool, dry, and well-ventilated area.
Moisture Control: Keep containers tightly sealed to prevent moisture absorption, as the powder is hygroscopic.
Stacking: Do not stack pallets too high to ensure stability and prevent bag damage.
Rain Protection: strictly prohibit exposure to rain during transportation and storage.

Safety Precautions

Dust Control: Titanium Dioxide acts as a nuisance dust. Avoid breathing dust.
PPE: Wear a standard dust mask (N95 or equivalent) and safety goggles when handling large quantities to prevent eye and respiratory tract irritation.
Skin Contact: Non-irritating to skin, but washing with soap and water after handling is recommended for hygiene.
Eye Contact: If powder enters eyes, rinse thoroughly with water.
Fire/Explosion: The product is non-flammable and non-explosive.
