Zr-Al Inorganic Coating Rutile Titanium Dioxide Sulphate Process Titanium Dioxide with Medium Durability and Excellent Gloss

SR-2377 RUTILE TITANIUM DIOXIDE

SR-2377 is a rutile titanium dioxide pigment from DOGUIDE GROUP. According to the supplied Technical Data Sheet (TDS), its pigment surface is treated with zirconium- and aluminum-based inorganic coatings and an organic treatment. The supplier describes the grade as designed for excellent gloss, medium durability and good dispersion. Its stated applications cover coatings, inks, paper, rubber, plastics and masterbatch.

This expanded report preserves the original supplier specifications and adds practical technical interpretation and suggested evaluation procedures. Suggested processing guidance and application tests are not supplier-certified performance claims.

Data note: All values in this table are specifications or typical data shown in the supplied TDS, not independent measurements of a particular production batch. The source does not specify detailed test methods for every property.

Pigment composition: The ≥93% TiO₂ content and ≥97% rutile content indicate a predominantly rutile TiO₂ pigment. These values support product identification but alone do not establish performance in any finished formulation.

Surface treatment: Zirconium and aluminum inorganic surface treatment, together with organic treatment, is stated by the manufacturer. Such treatment is relevant to pigment–binder interaction, wetting and dispersion; specific chemistry and loading are not disclosed.

Optical characteristics: Whiteness ≥97.0, L value ≥98.0 and tint reducing power ≥180% are supplier-reported indicators of optical performance. Opacity and color in finished systems should be validated under the customer’s own test methods.

Oil absorption: The 16–20 g/100 g range is relevant to pigment wetting, binder demand and formulation rheology. It does not prescribe a fixed pigment loading or dispersant dosage.

Moisture, residue and soluble matter: Low loss on heating, water-soluble matter and sieve residue limits provide incoming-quality references relevant to cleanliness and process consistency.

pH and electrical resistance: The pH range of 6.5–8.5 and specific resistance ≥8000 Ω·cm offer useful checks of aqueous dispersion compatibility and soluble ionic contamination.

Durability positioning: The supplier specifically describes medium durability. No numerical weathering, chalking or gloss-retention test results are included; high-durability outdoor use requires validation.

• Start with a controlled laboratory trial using the existing formulation as the benchmark; maintain identical pigment volume concentration or weight loading for comparisons.
• Evaluate wetting and dispersant compatibility before changing pigment loading. Record dispersion energy, temperature, time and grind fineness.
• For liquid coatings, assess viscosity, gloss, opacity, color, settling and storage stability using the customer’s normal test methods.
• For plastics and masterbatch, evaluate melt dispersion, speck count, color consistency and final article properties at representative processing conditions.
• For exterior applications, carry out accelerated and, where possible, natural weathering tests. The TDS claim of medium durability should not be interpreted as a quantified lifetime guarantee.
• Check compliance with market-specific regulatory, food-contact or other restricted end-use requirements independently; these are not established by the supplied TDS.

The supplier lists 25 kg full-paper bags and 500 kg or 1000 kg PP woven bags. Actual packaging configuration, palletization, net weight tolerances and shipping requirements should be confirmed with the supplier before purchase.

The source TDS does not provide a shelf life, detailed storage temperature, or complete safety instructions. As general powder-handling practice, store sealed packages in a clean, dry location; prevent contamination and dust release; and consult the current supplier Safety Data Sheet (SDS) for occupational controls, protective equipment and transport classification.

The supplied document does not provide measured batch results, weathering test hours, gloss-retention curves, particle-size distribution, refractive index, specific gravity, full surface-treatment chemistry, shelf life or regulatory declarations. This report does not invent values for those properties.

SR-2377 is presented by DOGUIDE GROUP as a Zr/Al-treated rutile titanium dioxide pigment offering excellent gloss, medium durability and good dispersion across several coatings and polymer applications. Its documented optical, chemical and physical specifications provide a basis for screening and incoming inspection. Final grade selection should rely on side-by-side formulation testing and up-to-date supplier documentation.
