Description
Titanium Dioxide Rutile 93% General Purpose
Titanium Dioxide Rutile 93% General Purpose (CAS 13463-67-7, molecular formula TiO2) is a coatings raw material used by paint, ink and adhesive formulators who need consistent dispersion, opacity and rheology from drum to drum. China Chemicals supplies it at TiO2 93% min in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as TiO2, Rutile Titanium Dioxide, Pigment White 6. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
Typical applications
- Primary white pigment in decorative and industrial paint
- Opacifier in plastics and masterbatch
- Whitening in paper, ink and laminate manufacture
- Coil, powder and automotive coating systems
- Rubber and cable compound whitening

What Is Titanium Dioxide Rutile?
TiO2 occurs in two commercially relevant crystal forms — rutile and anatase. Rutile has a higher refractive index, giving it stronger hiding power and, critically, much better resistance to UV-driven chalking and fading over time. This is why rutile dominates exterior paint, outdoor plastics and any application with long UV exposure, while the brighter-but-less-durable anatase form is reserved for interior paints, paper and applications without long-term sun exposure.
Rutile or Anatase: Which Should You Use?
This 93% general-purpose titanium dioxide rutile grade carries surface treatment (commonly alumina, silica or organic coatings) to improve dispersion and wetting across water- and solvent-based systems, and is formulated alongside extenders such as Iron Oxide Red and anti-corrosive pigments such as Zinc Phosphate in a finished coating system. Choose titanium dioxide rutile for anything with UV or outdoor exposure; anatase where brightness matters more than durability.
Handling & Safety
Titanium dioxide rutile is widely regarded as a low-toxicity, chemically stable pigment, insoluble in water. IARC classifies inhalable TiO2 dust as Group 2B (possibly carcinogenic to humans) based on high-dose animal inhalation studies — relevant to occupational dust exposure during bulk powder handling, not to use in a cured paint film. Standard dust control (local exhaust, dust mask for bulk handling) is the appropriate response.
Frequently Asked Questions
Rutile or anatase — which should I use?
Rutile for anything with UV or outdoor exposure (exterior paint, outdoor plastics) due to much better chalk resistance; anatase where brightness matters more than durability (interior paint, paper).
Is titanium dioxide rutile pigment safe?
Yes, chemically stable and low-toxicity in finished products; inhalable dust is IARC Group 2B based on animal studies, so standard dust control applies during handling.
What does surface treatment do for titanium dioxide rutile?
Alumina, silica or organic coatings improve dispersion, wetting and durability versus uncoated TiO2.
What packaging and order quantities are available?
