Features Of BASF ASP 400P Hydrous Kaolin

  1. Highly refined hydrous kaolin with consistent particle size distribution for optimal rheology control.

  2. Low abrasivity and high whiteness, supporting premium aesthetics in sensitive coating and ink systems.

  3. Excellent suspension stability in aqueous formulations due to balanced surface charge and low soluble salts content.

  4. Enhanced opacity and tint strength retention when used as a functional extender in titanium dioxide–containing systems.

  5. ISO 9001–certified manufacturing process ensuring batch-to-batch reproducibility and traceability.

Typical Applications Of BASF ASP 400P Hydrous Kaolin

  1. Water-based architectural coatings for improved scrub resistance and sheen uniformity.

  2. Industrial maintenance coatings requiring high solids content and controlled viscosity.

  3. Offset and flexographic printing inks where pigment dispersion stability and gloss consistency are critical.

  4. Specialty adhesives and sealants needing inert filler functionality without compromising open time or bond strength.

  5. Plastic masterbatches for polyolefin films, providing dimensional stability and surface smoothness.
