SEMITI 996

Universal Rutile

Our flagship chloride-process rutile — high tinting strength and broad compatibility for coatings, plastics, and inks.

International equivalents: LB R-996 · Tronox CR-828 · Ti-Pure R-902 (close)

SEMITI 996 is the workhorse universal-grade chloride-process rutile titanium dioxide. It is the direct technical and commercial counterpart to LB Group R-996, currently the highest-volume single grade in global TiO2 trade. Surface-treated with alumina and an organic stabilizer, SEMITI 996 is engineered to perform in waterborne and solventborne coatings, plastic masterbatch, PVC compounds, and printing inks — without forcing customers to qualify multiple "specialty" grades.

For coatings formulators, SEMITI 996 delivers consistent high gloss in industrial systems, controlled rheology in dispersions, and excellent storage stability. For compounders, the surface treatment ensures clean extrusion in PE/PP/PVC, minimal nozzle deposit, and excellent thermal stability up to 280°C. For ink makers, its narrow particle size distribution and easy dispersion behavior translate to higher milling efficiency and lower screen-blinding.

We supply SEMITI 996 ex-stock from Qingdao and Shanghai, with typical delivery to major Asian ports in 10–14 days, India / Middle East in 18–25 days, Europe / Latin America in 30–40 days.

Why customers pick SEMITI 996

  • 01Chloride process — narrow particle size distribution, brighter undertone than sulfate equivalents
  • 02Universal applicability — single SKU covers coatings + plastics + inks, simplifies procurement
  • 03Surface treatment optimized for waterborne and solventborne systems
  • 04Thermal stability up to 280°C — safe for PE/PP/PVC compounding
  • 05High batch-to-batch consistency from a tier-1 producer (1.5M t/y capacity)

vs international reference grades

Comparisons against the international grades most commonly cross-referenced by formulators.

Chemours Ti-Pure
R-902

Same chloride process, same end-uses. SEMITI 996 typically delivers within 5% of R-902 on tinting strength and gloss at 30–40% lower landed cost.

Tronox
CR-828

Direct competitor for plastics/coatings universal grades. SEMITI 996 has comparable thermal stability and slightly higher rutile content.

LB Group
R-996

Functionally equivalent — SEMITI 996 sources from the same tier-1 producer family. Same regulatory profile (REACH-registered, low Pb/Cd).

Kronos
2310

Kronos 2310 is similarly positioned for plastics + coatings. SEMITI 996 offers better tinting strength in waterborne systems; Kronos has slight edge in outdoor durability.

Primary applications

Architectural Coatings
Interior emulsion + exterior facade paints — the largest single TiO2 application by volume.
Industrial Coatings
Heavy-duty protective coatings for steel structures, infrastructure, and machinery — demands durability and chemical resistance.
Plastic Masterbatch
White masterbatch concentrates for PE, PP, ABS, PS film and injection molding — typically 50–70% TiO2 loading.
Printing Inks
Offset, flexo, gravure, screen, UV inks — easy dispersion, anti-screen-blinding, narrow particle size.

Packaging & shipping

25 kg paper bag with PE liner; 500 / 1000 / 1250 kg FIBC. Standard pallet 1 t. 20' container 18–20 t. No special handling required for ocean transport.

Common questions

Is SEMITI 996 REACH-registered?+
Yes. Titanium dioxide is REACH-registered as an existing substance (EC 236-675-5). We provide REACH compliance letter on inquiry. Note that the EU's 2022 classification of TiO2 as Carc. 2 (inhalation) only applies to powder forms with ≥1% respirable particles — SEMITI 996 is supplied as a non-respirable agglomerated powder and is exempt under most national implementations.
What's the difference between chloride and sulfate process?+
Chloride-process TiO2 (like SEMITI 996) is produced via TiCl4 → TiO2 vapor-phase oxidation. It has narrower particle size distribution, brighter undertone (lower b*), and less metallic impurity than sulfate-process TiO2. Sulfate process (see SEMITI 298) is 25–30% cheaper but better suited to applications where peak brightness is less critical.
Can SEMITI 996 be used in food-contact plastics?+
Yes for indirect food contact applications meeting FDA 21 CFR 178.3297 (colorants for polymers). For direct food contact, please request our food-grade variant SEMITI 996-FCM with full migration testing.
How does SEMITI 996 compare with R-902 in waterborne wood coatings?+
In our customer trials, SEMITI 996 matches R-902 within 2 units of CIE L* and within 1 unit of gloss at 60° in waterborne PU wood coatings. Settling behavior is comparable with proper anti-settling additive (0.3–0.5% fumed silica or rheology modifier).
