High brightness (ISO brightness ≥ 85) for superior whiteness in end products.
Fine particle size distribution with controlled D50 ≤ 2.5 µm, ensuring excellent dispersion and smooth finish.
Natural hydrous kaolin structure providing high chemical inertness and pH stability in aqueous systems.
Low abrasivity and low iron content (< 0.15% Fe₂O₃), minimizing equipment wear and color contamination.
Consistent rheological behavior enabling predictable viscosity control in coatings and inks.
Water-based architectural and industrial coatings as a functional extender and opacity enhancer.
Gravure and flexographic printing inks requiring high gloss, sharp print definition, and ink film integrity.
Paper coating formulations for premium glossy and matte coated papers.
Plastic masterbatches where optical clarity and thermal stability are critical.
Adhesives and sealants seeking improved filler loading without compromising bond strength or open time.
