Highly dispersed, plate-like hydrous kaolin particles for optimal reinforcement and opacity.
Low abrasivity and low oil absorption, supporting improved processability in high-solids formulations.
Consistent particle size distribution with narrow PSD profile, ensuring batch-to-batch reproducibility.
Natural white color and high brightness (ISO brightness >85), enhancing whiteness and tint strength in pigmented systems.
pH-neutral aqueous slurry form, minimizing formulation instability risks in water-based coatings and adhesives.
Water-based architectural coatings (e.g., interior flat and eggshell paints).
Industrial maintenance coatings requiring balanced rheology and film integrity.
Paper coating formulations for improved smoothness and printability.
Adhesives and sealants where controlled viscosity and filler suspension stability are critical.
Plastic masterbatches for functional filler applications in polyolefin films and molded parts.
