Rutile Clarity, Real-World Results: Field Notes on titania tio2

I’ve spent enough time in paint labs and plastics shops to know a good rutile from a merely decent one. The Free Sample TiO2 DongFang R5566 Titanium Dioxide—manufactured in Jindi Industrial Park, Dacheng County, Langfang City, Hebei—lands squarely in the “pleasant surprise” category. It’s surface-treated with zirconia and alumina and finished organically, which, to be honest, is what modern converters expect for dispersion and weathering. And yes, the gloss pop is there.

Quick Specs (real-world use may vary)

Process Flow (how it’s made and why it matters)

Feedstocks (ilmenite or TiCl4) → Oxidation to TiO2 → Calcination → Micronization (target PSD, D50 around 0.25 µm) → Surface treatment (zirconia/alumina) → Organic finish → Dust control & packaging. Testing follows ISO 787 for fineness, residue, moisture, and ASTM D476 classification. The zirconia shell is there for UV blocking and chalking resistance; the alumina helps with dispersion stability in both waterborne and solvent systems.

Where it shines

• Architectural and industrial coatings (exterior gloss/semigloss; service life ≈ 7–12 years depending on binder/film build).
• Plastics and masterbatch (PP, PE, PVC; low yellowness, easy dispersion in twin-screw).
• Printing inks and powder coatings (good opacity with controlled viscosity).
• Fiber & film (matting/opacity in BOPP and PET—watch moisture spec).

Many customers say they cut grind time by ~10–15% versus older sulfate rutile grades. I’ve seen that too—especially in medium-SVOC alkyds.

Case snippets

• Architectural paint maker (APAC): switched to titania tio2 R-5566 and reduced TiO2 loading by ≈4% while keeping 98 KU; 2-year outdoor panel retained 85% gloss. • Packaging film converter: whiteness +2 units and 8% faster extrusion startup due to cleaner screw purging. • Coil coating line: ΔE

Vendor landscape (my shorthand view)

Customization, QA, and Compliance

• Customization: PSD tuning (D90 targets), moisture ≤0.5%, tailored alumina level for waterborne systems, packaging in 25 kg bags or FIBCs.
• QA: ISO 9001 frameworks; batch COA with whiteness, oil absorption, residue (≤0.02%), density ≈4.1 g/cm³.
• Certs/regs: REACH registered; RoHS compliant; food-contact requires application-specific review (always).
• Testing: ISO 787 series; color-fastness via ΔE; ASTM D476 for classification.

If you need ultra-low VOC or high-gloss automotive clear, you may still benchmark against a top chloride grade. For architectural, industrial, inks, and plastics—this titania tio2 is a solid, economical pick.

Service life and handling tips

Expected outdoor durability in good acrylic systems runs 7–12 years; in PVC profiles, color hold is typically stable over 5–8 years (UV package dependent). Store dry, keep bags sealed, and pre-disperse with suitable wetting agents to hit that “one-pass” grind. Simple stuff, big impact.
