Key Features and Advantages
1. Excellent Opacity and Hiding Power
Thanks to its high refractive index and optimized particle size distribution, R-298 provides superior coverage and whiteness, reducing the amount of pigment needed in formulations.
2. UV and Weather Resistance
The rutile form of titanium dioxide is highly stable under UV light. R-298 enhances durability and gloss retention in both interior and exterior paint applications.
3. Easy Dispersion
With alumina and organic surface treatment, this grade disperses easily in both solvent- and water-based systems, helping reduce grinding time and improve stability in paints.
4. Strong Tinting Strength
R-298 exhibits strong tinting power and allows for precise and vibrant color formulation, making it ideal for both base coats and topcoats in decorative and protective coatings.
Applications in Paints and Coatings
-
Architectural Paints: Interior and exterior emulsions, primers, and finishes.
-
Automotive Coatings: Base and topcoats with superior gloss and UV stability.
-
Industrial Paints: Metal coatings, wood finishes, and corrosion-resistant layers.
-
Decorative Coatings: Artist paints, plasters, and specialty finishes.
Packaging and Storage
R-298 is typically supplied in 25 kg bags or 500–1000 kg jumbo bags, with customized packaging available upon request. It should be stored in cool, dry, and well-ventilated areas, away from moisture and direct sunlight. Proper handling ensures long-term stability and performance.
Conclusion
Rutile Titanium Dioxide 94% (Sulfate Process, R-298 Grade) is a cost-effective, high-performance pigment designed for demanding applications in the paints and coatings sector. With its superior opacity, UV resistance, dispersion characteristics, and durability, it remains a top choice for manufacturers aiming to produce high-quality, long-lasting coatings. Whether you’re formulating architectural, automotive, or industrial coatings, R-298 delivers reliability and exceptional aesthetic results.
