R818
Yuxing
As a premium rutile titanium dioxide engineered for superior aesthetic and protective performance, R818 stands out for its exceptional combination of high gloss and long-term weather resistance. This advanced pigment undergoes a proprietary dual-treatment process — featuring an inorganic zirconium-aluminum coating followed by organic modification — resulting in a product with ≥94% rutile content and outstanding multi-functional properties. With a precisely controlled average particle size of 0.3μm and whiteness value of ≥97%, R818 delivers brilliant optical performance while maintaining excellent dispersibility across various formulations. Its unique surface chemistry ensures exceptional weatherability, making it ideal for demanding outdoor applications where both appearance and durability are critical requirements.
R818 delivers exceptional gloss characteristics with a 60° gloss measurement of ≥90 in cured coating films, maintaining this high gloss level even after prolonged exposure to environmental factors. Its optimized particle size distribution (0.28-0.32μm) ensures efficient light reflection while minimizing surface scattering, contributing to the high-gloss finish prized in premium coatings. This property makes it particularly valuable for applications where visual appeal is a primary consideration.
Through its specialized zirconium-aluminum surface treatment, R818 provides outstanding resistance to UV degradation, chalking, and color fade. Accelerated weathering tests (QUV) confirm minimal performance degradation after 5,000+ hours of exposure, translating to excellent long-term durability in outdoor applications. This weather resistance extends the service life of coated products, reducing maintenance requirements and lifecycle costs.
The dual surface treatment of R818 — inorganic coating for weather resistance and organic modification for compatibility — ensures exceptional dispersion in both solvent-based and water-based systems. It achieves 95% particle separation within 20 minutes of mixing under standard conditions, reducing processing time and energy consumption. This efficient dispersion ensures uniform color development and consistent performance across production batches.
R818 maintains stable performance across a wide pH range (6.0-8.5) and exhibits excellent compatibility with various resin systems including acrylics, polyurethanes, and alkyds. Its controlled oil absorption (≤20g/100g) helps maintain optimal viscosity in coating formulations, providing formulators with greater flexibility in achieving desired performance characteristics without compromising application properties.
R818 is ideally suited for premium exterior architectural coatings requiring both aesthetic appeal and long-term durability. It performs exceptionally well in acrylic and fluoropolymer-based systems used on commercial buildings, residential properties, and infrastructure projects. The pigment's ability to maintain gloss and color integrity ensures that coated surfaces remain visually appealing for extended periods, even in harsh climatic conditions.
In industrial settings, R818 provides superior protection and appearance for steel structures, machinery, and equipment exposed to outdoor elements. Its weather resistance and corrosion-inhibiting properties make it suitable for use in industrial maintenance coatings, ensuring long-term performance in demanding environments such as chemical plants, power stations, and transportation infrastructure.
For PVC window profiles, door frames, and outdoor furniture, R818 delivers exceptional UV stability and color retention. It prevents photo-oxidation of polymer chains, maintaining mechanical properties and appearance over extended service life. Its excellent dispersion ensures uniform color throughout thick sections, eliminating streaking and flow marks in extrusion processes.
R818 finds specialized application in road marking paints and traffic signage, where high visibility and durability are essential. Its high reflectivity enhances nighttime visibility, while its weather resistance ensures long-term performance under constant exposure to traffic, weather, and UV radiation. This makes it a critical component in transportation safety materials.
R818's high gloss performance stems from its precise particle size control (0.3μm) and specialized surface treatment that minimizes light scattering at the film surface. The uniform particle distribution ensures smooth film formation, while the inorganic coating enhances light reflection properties, resulting in the ≥90 gloss rating at 60° measurement that distinguishes premium finishes.
The proprietary zirconium-aluminum inorganic coating creates a protective barrier that shields the pigment and underlying binder from UV radiation and moisture ingress — primary causes of coating degradation. This barrier effect, combined with the inherent stability of its ≥94% rutile content, significantly slows the photo-oxidation process, extending service life in outdoor applications.
