Rutile Titanium Dioxide R-5569 - High Whiteness and Durability for Paints
Rutile Titanium Dioxide R-5569: Superior Opacity and Weather Resistance for Premium Coatings
In the pursuit of flawless surface finishes and long-lasting protection, Rutile Titanium Dioxide R-5569 stands as the pinnacle of pigment technology. Engineered for manufacturers of high-performance coatings, this advanced-grade TiO₂ delivers unmatched whiteness, durability, and cost efficiency, redefining standards for industrial and architectural paint systems exposed to extreme environmental conditions.
Product Overview
R-5569 is a chlorine-process rutile titanium dioxide pigment featuring proprietary surface treatment and crystal structure optimization. Designed for solvent-borne and water-based coatings, it combines exceptional light scattering efficiency with robust resistance to UV degradation, making it the ideal choice for exterior applications where color retention and film integrity are non-negotiable.
Key Performance Advantages
1. Unrivaled Optical Properties
- CIE Whiteness Index: 98.5+ (ISO 2470-2)
- Opacity Enhancement: 25% higher hiding power vs. standard rutile grades (ASTM D2805)
- Undertone Control: Neutral blue-white base for truer color development
2. Extreme Environmental Durability
- UV Resistance: 98% gloss retention after 4,000 hrs QUV-B exposure (ASTM D4587)
- Chalking Resistance: Class 1 rating after 24 months Florida exposure (ASTM D4214)
- Chemical Stability: Resists acid rain (pH 3.0–10.0) and alkali attack
3. Optimized Processing Efficiency
- Oil Absorption: 18–20 g/100g (ASTM D281)
- Dispersibility: Hegman grind ≤15 μm with 30% energy reduction
- Compatibility: Stable in alkyd, epoxy, acrylic, and PU systems
4. Sustainable Formulation
- REACH & RoHS compliant
- NSF/ANSI 61 certified for potable water contact

Mechanism of Action
R-5569 achieves superior performance through three synergistic mechanisms:
- Optimal Light Scattering: Precisely engineered particle size distribution maximizes Mie scattering efficiency for enhanced opacity.
- Surface Passivation: Zirconia-alumina coating neutralizes photocatalytic activity, reducing TiO₂-induced polymer degradation by 70%.
- Durability Matrix: Dense rutile crystals coupled with surface treatments create a barrier against:
- Hydroxyl radical formation
- Moisture penetration (0.02 g/m²/day @ 50μm DFT)
- Thermal expansion mismatch stresses
Formulation Guidelines
Recommended Loading Levels
- Water-based paints: 18–25% by weight
- Solvent-borne systems: 20–30% by weight
- High-build coatings: 30–35% by weight
Dispersion Protocol
- Premix with resin/solvent at 1:1 ratio
- High-speed dispersion: 2,000–2,500 rpm for 25 mins
- Finalize with 30–60 mins bead milling (2.0–2.5 mm ZrO₂ beads)
Compatibility Matrix
| Resin System | Compatibility | Optimal PVC Range |
|---|---|---|
| Acrylic Emulsion | Excellent | 18–28% |
| Epoxy | Excellent | 22–32% |
| Alkyd | Good | 20–30% |
| Polyurethane | Excellent | 15–25% |
| Fluoropolymer | Fair | 12–18% |
