BASF ASP 172 Hydrous Kaolin

BASF ASP 172 Hydrous Kaolin is a high-purity, plate-like hydrous kaolin clay from BASF’s ASP series—designed for rheology control, opacity enhancement, and improved suspension in water-based coatings, inks, and adhesives. Its narrow particle size distribution and consistent surface chemistry ensure excellent dispersion, gloss retention, and formulation stability across industrial applications.

Features Of BASF ASP 172 Hydrous Kaolin

  1. Highly dispersible hydrous kaolin with optimized particle size distribution for improved suspension stability.

  2. Low abrasivity and gentle on processing equipment, supporting extended mill life and reduced maintenance.

  3. Natural white color and high brightness (ISO 1147–1998) enhance whiteness and opacity in end formulations.

  4. Controlled pH (aqueous slurry) ensures compatibility with a broad range of water-based systems including acrylics and vinyl dispersions.

  5. Consistent batch-to-batch quality supported by BASF’s stringent global manufacturing controls and traceability.

Typical Applications Of BASF ASP 172 Hydrous Kaolin

  1. Architectural and industrial waterborne paints and coatings.

  2. Interior and exterior flat and low-sheen decorative paints.

  3. Printing inks, especially for high-opacity matte finishes.

  4. Adhesives and sealants requiring rheology control and filler functionality.

  5. Plastics masterbatches where brightness and dispersion stability are critical.
