TITANIUM DIOXIDE R-996 FOR INDUSTRIAL USE TIO2: Field Notes, Specs, and Real-World Use

I spent a morning in Jindi Industrial Park, Dacheng County, Langfang City, Hebei Province—not the kind of place you stumble into by accident—to look at Titanium Dioxide R-996 batches headed for coatings and plastic lines. It’s industrial-grade only (to be absolutely clear: not for food or pharma), and it’s the sort of rutile pigment that quietly makes white look whiter and colors pop harder.

What’s new in the TiO2 market (and what isn’t)

Demand in architectural coatings is steady; plastics masterbatch is still chasing dispersion and blue undertone. Energy costs and carbon accounting keep nudging buyers toward efficient grind times and high tint strength—because honestly, a lower let-down ratio saves more than a press release about “sustainability.” Many customers say R-996 grades give reliable hiding in PVC profiles and exterior paints without drama. I’ve seen that too.

Typical Technical Specifications (Rutile R-996)

Process Snapshot (Sulfate-route, simplified)

• Materials: ilmenite/titanium slag, sulfuric acid, neutralizers; alumina/silica for surface treatment.
• Methods: digestion → hydrolysis → calcination → micronization → surface treatment → drying → milling.
• Testing: ISO 591-1 and ASTM D476 classification; ISO 787 methods; ISO 2813 gloss; ISO 7724 color; ISO 16474 weathering.
• Service life: in exterior acrylics, around 5–10 years depending on binder, PVC, and UV; plastics vary with stabilizer package.
• Industries: paints & coatings, plastics/construction, packaging; not for food/pharma (as stated).

Where it shines (and why)

Titanium Dioxide R-996 offers high hiding power and a slightly blue undertone—useful for crisp whites and cooler tints. In plastics, fast dispersion shortens extruder time; in paints, you’ll often see lower scrub-loss and cleaner tint pastels. Many processors say they can shave 3–8% off TiO₂ loading in select formulas without losing opacity. Your mileage, of course, depends on resin and grind.

Customization and packaging

• Surface treatment tuning: higher Al/Si for weatherability; organic finish for faster dispersion.
• Target PSD for masterbatch vs. architectural coatings.
• Moisture control for powder coatings.
• Packs: 25 kg bags, 500–1000 kg FIBCs; palletized, shrink-wrapped.

Two quick case notes

1) Exterior acrylic wall paint (semi-gloss): switching to Titanium Dioxide R-996 cut grind time by ≈ 12% and improved contrast ratio by 1–2 points at the same PVC. After 1,000 h QUV (ISO 16474-3), ΔE stayed under 1.5. Not bad.

2) White PP masterbatch (film): line speed up 6% at equal opacity with a slightly lower TiO₂ loading (≈ –4%). Operators said pellets “felt cleaner” in the hopper—informal, but I’ve heard it before.

Compliance and safety notes

Factory typically operates under ISO 9001. Material is intended for coatings and plastics; not for food or pharma. Follow local regulations, dust control, and labeling; check EU CLP notes on certain TiO₂ forms. Always validate to ISO/ASTM standards in your own lab—because, to be honest, every resin system has its quirks.
