Performance Advantages of Pangang CR-350

High Whiteness and High Brightness. CR-350 titanium dioxide exhibits high whiteness with a brightness value generally above 95%, ensuring clean, bright coloration in paints, plastics, and inks.
Excellent Hiding Power. The rutile crystal form and controlled particle size provide excellent opacity and light-scattering ability, enabling efficient coverage with lower pigment loading.
Superior Dispersibility. Due to its optimized surface treatment, Pangang CR-350 disperses quickly and uniformly in water-based and solvent-based systems, as well as plastic matrices, minimizing agglomeration and enhancing processing efficiency.
Good Weatherability and Light Stability. The chloride-process rutile structure combined with ZrO₂/Al₂O₃ surface coating provides strong resistance to UV degradation, chalking, yellowing, and color fading—ideal for outdoor applications.
Chemical Stability and Thermal Resistance. CR-350 maintains excellent color stability and physical performance under heat, light, and chemical exposure. It is compatible with most resins, solvents, plasticizers, and additives.
Low Oil Absorption. Its moderate oil absorption (typically ≤20 g/100 g) helps maintain formulation stability, reduce viscosity, and improve processability in coatings and plastics.

Recommended Applications

Coatings. Titanium dioxide Pangang CR-350 is widely used in architectural coatings for both interior and exterior surfaces, industrial paints, high-gloss coatings, automotive refinishing paints, and powder coatings. Its high whiteness, excellent hiding power, and strong weather resistance make it ideal for these applications.
Plastics. In plastics, CR-350 is compatible with a broad range of materials, including PP, PE, PVC, PS, ABS, PET, and engineering plastics. It is extensively applied in color masterbatches, injection and extrusion products, as well as sheets, profiles, pipes, and films. Its good dispersibility ensures uniform coloration and high-quality finished products.
Printing Inks. CR-350 is suitable for both solvent-based and water-based printing inks. It performs well in flexographic, gravure, and screen printing systems, providing excellent opacity, whiteness, and color stability in printed materials.
Other Applications. Beyond coatings, plastics, and inks, CR-350 finds applications in rubber and synthetic materials, leather finishing, specialty papers, and other products where high whiteness, opacity, and durability are required. Its chemical stability and lightfastness make it ideal for these demanding industrial uses.

Storage and Handling Recommendations
