Highly purified natural hydrous kaolin with consistent particle size distribution for optimal rheology control.
Low abrasivity and high whiteness (ISO brightness >85) enhancing aesthetic performance in coatings and plastics.
Excellent dispersion stability in aqueous systems, supporting efficient formulation and reduced processing energy.
Neutral pH and low soluble salt content ensure compatibility with sensitive binders and pigments.
Reproducible surface chemistry enabling reliable functional performance across production batches.
Water-based architectural and industrial coatings as a functional extender and rheology modifier.
Paper coating formulations to improve gloss, printability, and ink receptivity.
Plastic compounds (e.g., PVC, PP) for opacity enhancement and dimensional stability.
Adhesives and sealants requiring controlled viscosity and filler reinforcement.
Specialty inks where high brightness and low oil absorption are critical.
