Nantai Rutile Titanium Dioxide NR-950 for Coatings, Paints, and Plastics
Product Overview
Nantai Rutile Titanium Dioxide NR-950 is a premium-grade inorganic pigment engineered to deliver unmatched performance in coatings, plastics, and industrial applications. With TiO₂ content ≥92%, rutile crystallinity ≥98%, and volatile matter ≤0.5%, this pigment combines exceptional optical properties with robust processing stability. Certified to ISO 9001 and REACH standards, NR-950 is optimized for high-temperature environments and demanding formulations, offering superior hiding power (scattering coefficient >90%), low oil absorption (≤23 g/100g), and broad pH adaptability (6.0–8.5).
Ideal for solvent- and water-based systems, NR-950 ensures consistent whiteness (L* ≥95) and chemical inertness (resistivity >50 Ω·m), making it the go-to choice for manufacturers prioritizing durability, cost efficiency, and regulatory compliance. Available for spot purchases or bulk contracts, this pigment supports global supply chains with ≤7-day lead times and 99% batch-to-batch consistency.
Technical Superiority & Competitive Advantages
1. Precision-Optimized Particle Design
- Narrow Particle Distribution:
- 45μm sieve residue ≤0.05% (ISO 787-7) ensures uniform dispersion and film smoothness.
- D50 particle size 0.28–0.35 µm maximizes light scattering efficiency.
- Surface Treatment Excellence:
- Dense inorganic coating (SiO₂/Al₂O₃) enhances weather resistance and anti-chalking properties.
- Organic treatment compatibility for tailored hydrophobicity or polarity.
2. Unrivaled Optical Performance
- Opacity Leadership:
- Scattering power ≥100% (vs. CRM) reduces pigment loading by 15–20%.
- Contrast ratio ≥97% at 20µm coating thickness (ASTM D2805).
- Color Consistency:
- Blue-phase whiteness (L* ≥95, b* ≤1.5) for vibrant, neutral undertones.
- 60° gloss ≥90 GU in alkyd resins (ASTM D523).
3. Robust Process Stability
- Thermal Resistance:
- Volatile matter ≤0.5% at 105°C (ISO 787-2) minimizes foaming in extrusion.
- Suitable for baking coatings (180–220°C) without yellowing.
- Chemical Inertness:
- Water solubility ≤0.3% (ISO 787-3) enhances moisture resistance.
- Resistivity >50 Ω·m (ISO 787-14) ensures compatibility with corrosive media.
