Product Performance

Excellent dispersibility. Through advanced particle size control and deagglomeration technologies, combined with inorganic and organic treatment processes, Pangang R 298 disperses quickly and evenly in a variety of application systems, significantly reducing agglomeration. This characteristic not only improves production efficiency but also ensures consistent product quality. For example, in paint production, it allows titanium dioxide to disperse rapidly in binders such as resins, shortening mixing times and resulting in a more uniform color after application.
Excellent whiteness and blue undertone. Unique impurity removal and particle size control technologies result in extremely low impurity content, resulting in fine, uniform pigment particles. This microstructure enhances blue light scattering, resulting in exceptional whiteness and a refreshing blue undertone. On white plastics or printed materials using white ink, it creates a whiter, purer visual effect, enhancing product appearance.
High gloss. Its uniform, concentrated particle size distribution ensures a smooth, even surface when forming a paint film or coating. Light reflects more regularly on such a surface, achieving an exceptionally high gloss. In coatings requiring high gloss, such as automotive and furniture paints, R298 creates a radiant finish, enhancing the product’s aesthetics and premium quality.
High hiding power. Advanced particle size control and deagglomeration technology result in fine, concentrated particles, maximizing light scattering efficiency. This gives R298 exceptional hiding power. When used in coatings, inks, and plastics, it effectively conceals underlying colors or impurities, reducing usage while maintaining excellent hiding power. For example, in architectural coatings, a small amount of R298 can effectively cover wall imperfections and base colors.
High weather resistance. R 298 titanium dioxide has a high rutile content, resulting in a complete crystal lattice and strong stability. Furthermore, the advanced, dense inorganic coating provides a strong protective layer, resulting in excellent lightfastness, chalking resistance, and weather resistance. Even under long-term exposure to outdoor or harsh environments, such as in outdoor architectural coatings and automotive topcoats, R 298 maintains stable color, resists fading and chalking, and extends product life.
Excellent leveling properties. A special organic surface treatment imparts excellent leveling properties to R298. In coatings and ink systems, it promotes uniform coating spread, effectively reducing common post-application surface defects such as cracking, pinholes, and craters, resulting in smoother, flatter coatings and improved finish quality. For example, in printing inks, it ensures even distribution of ink across the paper surface, resulting in clearer, more detailed printed designs.
Low abrasion resistance. A special hydrolysis, salt treatment, and calcination process renders titanium dioxide particles relatively soft, significantly reducing wear on equipment during processing. This characteristic is particularly advantageous in high-shear applications, such as high-speed mixing and grinding in plastics processing, extending equipment life and reducing maintenance costs.
Excellent water resistance. Due to its intact and stable crystal lattice and dense inorganic coating, titanium dioxide R 298 resists discoloration when exposed to water. In water-related application scenarios such as water-based ink or offset printing, it exhibits good water resistance, ensuring the stability and color durability of the product in humid environments.

Main Applications of Rutile Titanium dioxide R 298

Coatings Industry

Architectural coatings. Whether used in interior matte, semi-gloss, or high-gloss latex paints, or various types of outdoor latex paints, titanium dioxide R 298 delivers on its strengths with high whiteness, high hiding power, excellent leveling, and weather resistance, ensuring long-lasting, vibrant wall colors while also providing excellent decorative and protective properties.
Industrial paints. In industrial coatings such as automotive paints (including topcoats, primers, and refinishing paints), powder coatings, coil coatings, appliance paints, container paints, anti-corrosion paints, marine paints, roadway paints, and high-solids paints, R298’s high gloss, high hiding power, weather resistance, and low abrasion properties meet the high-performance coating requirements of industrial products, enhancing product quality and appearance.
Wood coatings. Providing a high-gloss, high-whiteness coating for wood surfaces, Pangang R 298 protects the wood while enhancing its aesthetics, adding a touch of sophistication to furniture, wood floors, and other wood products.

Ink industry. R 298 is suitable for various printing inks, including offset inks, flexographic inks, letterpress inks, gravure inks, screen printing inks, and iron plate inks. Its excellent dispersibility, high whiteness, and high hiding power ensure uniform ink transfer and good printability during the printing process. Printed designs are vibrant, clear, and have excellent gloss and durability.

Plastic coloring. It can be used to color a variety of plastic products, including PE/PP, PVC, ABS, PS, polycarbonate, nylon, and thermoset polyester. During plastic processing, the excellent dispersibility of titanium dioxide R 298 ensures uniform color distribution. Its high whiteness and weather resistance ensure that plastic products maintain their vibrant color and stable performance even in long-term use and outdoor conditions.

Papermaking industry. In the production of decorative paper, Bible/dictionary paper, banknote paper, white board paper, coated paper, etc., R 298 titanium dioxide can enhance the whiteness and opacity of paper, improve the printing performance and appearance quality of paper, make the paper whiter and smoother, and produce clearer and more delicate printing effects.

Packaging and Storage

Packaging: R-298 titanium dioxide is typically packaged in 25 kg paper-plastic mixed bags. 500 kg and 1000 kg plastic woven bags are also available to meet different customer needs.
