Representative ranges. Final acceptance limits (whiteness L* / b*
undertone, gloss, residue on 45 µm, volatile at 105 °C,
water‑soluble salts, FPV, abrasion) are application‑specific and
will match the lot COA.

| Zn‑Ti (Zn‑modified) | Plastics/masterbatch | Blue undertone; reduced photo‑activity; low FPV. |
| Al‑organic | Plastics/ink | Organic treatment for flow and wetting in non‑polar systems. |

• High‑hiding white pigment for coatings (architectural,
industrial).
• Plastics & masterbatch (PP/PE/PVC/ABS) with blue/neutral undertone options. • Printing inks and paper coating for brightness/opacity. |
• 25 kg multi‑wall bags (PE‑lined); 500–1,000 kg FIBCs.
• Small packs for R&D and plant trials. |
• Non‑DG. Avoid generating respirable dust; use LEV & PPE.
• Store cool/dry; keep sealed to prevent moisture pick‑up and caking. |
Regulatory: Certain jurisdictions require specific labeling for
TiO₂ powders containing respirable particles. SDS provides
guidance on dust controls and workplace exposure limits.
