Representing the pinnacle of pigment technology, Top Quality Aluminium Silicate Tio2 Titanium Dioxide Rutile R818 sets new standards for performance in demanding applications across multiple industries. This premium rutile-grade pigment undergoes a sophisticated dual treatment process — inorganic aluminum-silicate coating followed by organic modification — resulting in a product with 98.5% rutile content and exceptional multi-functional performance. With a precisely engineered average particle size of 0.32μm, it delivers superior optical properties, weather resistance, and dispersibility that make it indispensable for high-performance formulations. Compliance with international standards including ISO 18473-4 and ASTM D476-15 confirms its quality, while its versatility across plastics, coatings, and inks has established it as a top choice for manufacturers requiring uncompromising performance.
R818 features a proprietary two-stage surface treatment: a dense aluminum-silicate inorganic layer that provides UV protection and chemical resistance, followed by an organic modification that enhances compatibility with polymer systems. This combination delivers superior weather resistance (5,000-hour QUV testing with minimal color change) while ensuring excellent dispersion in both polar and non-polar matrices. The inorganic layer acts as a barrier against moisture and chemicals, while the organic layer reduces interfacial tension between pigment and binder.
With a whiteness value of 97.8% and a hiding power rating of 100% at 25μm dry film thickness, this titanium dioxide delivers exceptional brightness and opacity. Its optimized particle size distribution (0.30-0.34μm) maximizes light scattering efficiency, providing brilliant white finishes that retain their luster even after prolonged exposure to sunlight. In colored formulations, it enhances color intensity and stability, ensuring vibrant, long-lasting hues.
Unlike many specialty titanium dioxides optimized for single applications, R818 demonstrates exceptional compatibility across diverse formulations including PVC, polyethylene, polyurethane coatings, and solvent-based inks. This versatility stems from its balanced surface energy (35-40 mN/m) that allows it to integrate seamlessly into both polar and non-polar systems without compromising performance or requiring formulation adjustments.
R818 is the pigment of choice for premium exterior architectural coatings and industrial finishes requiring long-term weatherability. It performs exceptionally well in fluoropolymer and acrylic coatings used on commercial buildings, bridges, and infrastructure, providing resistance to UV degradation, chalking, and color fade even in extreme climates. Its durability makes it ideal for projects with 15+ year performance warranties.
In PVC window profiles, door frames, and outdoor furniture, this titanium dioxide provides exceptional UV stability and color retention. It prevents photo-oxidation of polymer chains, maintaining mechanical properties and appearance for extended service life. Its excellent dispersion ensures uniform color throughout thick sections, eliminating streaking and flow marks in extrusion processes.
For high-end packaging inks and industrial printing applications, R818 delivers superior opacity, gloss, and printability. It performs exceptionally well in gravure and flexographic inks used on plastic films and paperboard, providing excellent adhesion and rub resistance. Its fine particle size ensures sharp image definition and consistent color reproduction across large print runs.
Its advanced aluminum-silicate coating provides superior protection against UV radiation and moisture ingress, two primary causes of coating degradation. Accelerated weathering tests confirm that coatings containing R818 retain 90% of their original gloss and less than 5% color change after 5,000 hours of exposure — performance levels that translate to 15+ years of service in real-world conditions.
R818 maintains excellent thermal stability at processing temperatures up to 230°C, making it suitable for engineering plastics requiring high-temperature extrusion or injection molding. It does not decompose or discolor during processing, ensuring consistent performance in demanding applications such as automotive plastic components.
For best results, use high-shear mixing (3,000-5,000 RPM) during initial dispersion, followed by medium-shear mixing to incorporate into the final formulation. The pigment's surface treatment allows for shorter dispersion times (typically 20-30 minutes) compared to conventional rutile grades, reducing energy consumption while ensuring complete particle separation.
