High brightness (ISO brightness >94%) for superior whiteness in demanding applications.
Optimized particle size distribution with narrow PSD and high surface area for enhanced dispersion and opacity.
Consistent calcination ensures low residual carbon and minimal volatile content, supporting color stability and low odor.
Excellent chemical inertness and pH neutrality (pH 6.5–7.5 in aqueous slurry), ensuring compatibility with sensitive resin systems.
Low abrasivity compared to alternative functional fillers, reducing wear on processing equipment.
High-performance architectural and industrial waterborne paints and coatings.
Premium interior and exterior flat/matte finish wall paints.
UV-curable and low-VOC decorative coatings requiring high filler loading without compromising film integrity.
Specialty printing inks where brightness, rheology control, and gloss uniformity are critical.
Plastic compounds for automotive interior trim and consumer goods requiring consistent color and surface aesthetics.
