TIO2 Professional FAQ (Material, Specs, Standards)
1. What is the main difference between rutile and anatase tio2?
Rutile tio2 has higher refractive index (2.7), lower photoreactivity, and better weather resistance compared to anatase, making it preferred for outdoor, UV-stable applications. Anatase is more photocatalytic due to its bandgap (~3.2 eV) and is utilized in photocatalysis and solar cells.
2. What surface treatments are applied for enhanced tio2 performance?
Surface treatments such as ZrO₂ (Zirconia), Al₂O₃ (Alumina), and organic coatings are applied to improve dispersion, chemical resistance, reduce photoactivity, and prevent pigment-agglomeration—critical in plastics and coatings industries.
3. What standards define tio2 quality?
Typical standards include ISO 591-1 (pigment type specification), ASTM D476 (paints & coatings), EN 12873-2 (migration in water), and quality management under ISO 9001. SR-2377 meets or exceeds all these requirements.
4. How is tio2 lifetime tested?
Product is tested using QUV accelerated weathering (ISO 16474-3), chemical resistance baths (acid/alkali), and outdoor exposure panels. A 5-year QUV test shows ≥90% original brightness remains for SR-2377 in PVC coating panels.
5. Can SR-2377 be used in potable water or food-contact plastics?
Yes: With >94.5% purity, passivation layer, and EN 12873-2 compliance, it’s suitable for water pipes and food-grade films where indirect food contact is permitted (check local regulations).
6. What are key installation/processing notes for industrial use?
Store at 5-35°C, avoid humidity. Use high-shear mixing for rapid dispersion. Follow the manufacturer's guide for optimal integration in polymer or paint systems. Panel tests recommended.
7. Who are the main global users of tio2 powders?
Major paint, plastics, automotive, pipe, and masterbatch manufacturers, including PPG, AkzoNobel, BASF, Dow, PolyOne, Jushi Group, rely on certified tio2 in their value chain.
Conclusion & Industry Authority Resources
The evolution of tio2, from process innovation to application engineering, marks it as the backbone pigment for the modern paint, plastics, and advanced materials sectors.
