Product Characteristics of Dongfang R-5569

High Whiteness and Brightness. Titanium dioxide R-5569 exhibits a high level of whiteness and gloss, giving end products a clean and visually appealing appearance. Its high brightness index makes it suitable for high-quality white or light-colored formulations.
Excellent Hiding Power. With a high scattering coefficient and strong tinting strength (Reynolds number typically ≥1900), the pigment provides excellent opacity. Even at lower dosage levels, it delivers strong coverage and color strength.
Superior Dispersibility. The surface modification technologies applied to R-5569 significantly enhance its dispersibility in both aqueous and non-aqueous systems. It easily integrates with inks, coatings, and plastic matrices, helping achieve uniform particle distribution and smooth processing.
Low Oil Absorption. The pigment features a relatively low oil absorption value, helping to maintain stable viscosity in inks and coatings and contributing to improved processing efficiency in plastics.
Excellent Weather Resistance and Durability. As a rutile-type titanium dioxide, Pangang R-5569 provides strong resistance to UV degradation, discoloration, and chalking. It is suitable for applications requiring long-term outdoor durability.
Good Chemical and Thermal Stability. The pigment maintains stable structure and color under various processing conditions, including high-temperature plastic extrusion and coating curing processes.

Main Applications

Inks. Pangang R-5569 is well suited for a wide range of ink systems, including printing inks, packaging inks, and both solvent-based and water-based formulations. It delivers excellent opacity, gloss, and dispersion, making it ideal for high-precision and high-quality printing applications.
Coatings. In coating formulations, R-5569 is used extensively in architectural paints for both interior and exterior use, as well as in industrial coatings, powder coatings, anti-corrosion systems, and wood coatings. Its strong hiding power and stable weather resistance ensure durable performance and consistent visual quality in demanding environments.
Plastics. R-5569 performs effectively in plastic applications such as PVC, PP, ABS, PS, and PE, including masterbatches, profiles, pipes, sheets, films, and various injection or extrusion-molded products. Its high whiteness and opacity, combined with low oil absorption, help maintain mechanical integrity and processing stability without negatively affecting melt flow behavior.
Rubber, Leather, Paper and Other Industries. Besides, R-5569 is also suitable for synthetic leather, rubber formulations, paper coatings, and other industrial products that require consistent whiteness, strong covering ability, and stable long-term performance.

Storage and Handling

Store in a dry, ventilated environment, away from moisture.
Keep packaging sealed to prevent contamination.
Handle the powder with general protective equipment to avoid inhalation and eye contact.
When dispersing into inks, coatings, or plastics, adjust processing conditions properly to ensure optimal performance.
