Highly purified natural hydrous kaolin with consistent particle size distribution for optimal rheology control.
Low abrasivity and excellent suspension stability in aqueous systems, reducing equipment wear and sedimentation.
Neutral pH and low soluble salt content, ensuring compatibility with sensitive binders and additives.
Enhanced brightness (ISO 2470) and whiteness for improved opacity and color fidelity in coatings and plastics.
Optimized platelet morphology delivering superior reinforcement and barrier properties in polymer composites.
Water-based architectural and industrial coatings for improved sheen control and scrub resistance.
Paper coating and filling to enhance printability, smoothness, and ink holdout.
Thermoplastic and thermoset composites requiring dimensional stability and surface finish refinement.
Adhesives and sealants where controlled viscosity and anti-sag performance are critical.
Pharmaceutical excipients and cosmetic formulations requiring USP-grade purity and low heavy metal content.
