Highly purified natural hydrous kaolin with low soluble salt content for enhanced formulation stability.
Optimized particle size distribution to improve opacity, gloss control, and rheological behavior in coatings.
Consistent brightness (ISO 2470) and low iron oxide impurities, supporting color fidelity in premium white systems.
Excellent suspension performance in water-based formulations due to controlled surface charge and particle morphology.
Low abrasivity and high chemical inertness, making it suitable for sensitive polymer matrices and pigment dispersions.
Architectural interior and exterior waterborne wall paints.
Industrial maintenance coatings requiring balanced opacity and sandability.
Printing inks—especially offset and flexographic formulations where ink transfer and drying behavior are critical.
Plastic masterbatches for polyolefins and PVC, enhancing dimensional stability and surface finish.
Adhesives and sealants requiring non-reactive, low-viscosity fillers with good wetting characteristics.
