Titanium Dioxide White Powder R108 - Superior Brightness for Paints and Plastics
Titanium Dioxide R108 is a high-performance rutile-grade pigment designed to deliver unparalleled brightness, opacity, and durability in demanding industrial and decorative applications. As the benchmark for premium whitening agents, this advanced TiO₂ powder leverages cutting-edge surface treatment technology to meet the evolving needs of coatings, plastics, and specialty material manufacturers. With its exceptional light-scattering efficiency and eco-conscious formulation, R108 sets a new standard for brilliance and sustainability in modern manufacturing.
Product Features
1. Unmatched Brightness & Opacity
Titanium Dioxide R108 achieves a 97.5% reflectance at 457 nm wavelength, outperforming standard rutile grades by 8–12%. Its optimized crystal structure and narrow particle size distribution (0.2–0.3 µm) ensure:
- Ultra-high hiding power: Covers substrates in single-coat applications (≤35 µm film thickness).
- Neutral undertone: Eliminates yellowing in white plastics and UV-exposed coatings.
- Gloss enhancement: Boosts DOI (Distinctness of Image) to >90 in automotive clearcoats.
These properties make R108 indispensable for premium architectural paints, automotive finishes, and high-clarity packaging films.
2. Advanced Weathering Resistance
R108’s proprietary alumina-silica coating provides multi-layer protection against environmental stressors:
- UV durability: Retains 95% gloss after 2,000 h QUV-B exposure.
- Chalk resistance: ≤1% weight loss in ASTM D4214 testing.
- Acid rain tolerance: Stable in pH 3–11 environments, ideal for exterior building facades.
This resilience ensures long-lasting color fidelity in outdoor plastics (e.g., window profiles, stadium seats) and marine coatings.
3. Eco-Compliant Formulation
Engineered for sustainability without compromising performance:
- Heavy metal-free: Complies with REACH, RoHS, and FDA 21 CFR 178.3297.
- Low VOC profile: Enables compliance with EU Decopaint Directive 2004/42/EC.
- Closed-loop production: 98% recycling rate for process byproducts.
Manufacturers can confidently use R108 in toys, food-contact plastics, and green building certifications (LEED, BREEAM).
4. Superior Dispersion & Processability
The hydrophobic surface treatment of R108 ensures seamless integration into diverse systems:
- Low energy dispersion: Achieves Hegman 7+ fineness with 20% less milling time.
- Thermal stability: Withstands extrusion temperatures up to 300°C (plastics).
- Rheology control: Maintains viscosity stability in high-solids coatings (≥80% NV).
These attributes reduce production costs while enhancing throughput in injection molding and coil coating lines.
5. Chemical Inertness
R108 demonstrates exceptional resistance to:
- Solvents: No swelling in ketones, esters, or hydrocarbons.
- Alkalis/Acids: pH-stable in cementitious matrices (e.g., concrete coatings).
- Oxidation: Zero catalytic activity in polyolefin degradation.
This inertness expands its utility to industrial maintenance paints and flame-retardant polymer composites.
