Features Of BASF Sokalan PA 20 PN Surfactant

  1. High-performance polyacrylate-based polyelectrolyte dispersant with excellent colloidal stabilization capability.

  2. Low-foaming formulation suitable for high-shear industrial processes and automated dosing systems.

  3. Effective in both hard and soft water conditions, maintaining performance across a broad pH range (pH 4–10).

  4. Non-ionic character combined with anionic functionality ensures compatibility with cationic and non-ionic additives.

  5. Eco-preferred profile: APEO-free, biodegradable backbone, and compliant with major global regulatory frameworks (e.g., REACH, TSCA).

Typical Applications Of BASF Sokalan PA 20 PN Surfactant

  1. Cementitious systems: Enhances dispersion of cement particles and supplementary cementitious materials (SCMs) in ready-mix concrete.

  2. Construction chemical formulations: Key rheology modifier in tile adhesives, grouts, and self-leveling compounds.

  3. Mineral processing: Stabilizes pigment and filler suspensions in aqueous slurries for ceramics and coatings.

  4. Industrial cleaning concentrates: Improves soil suspension and prevents redeposition on hard surfaces.

  5. Water-based architectural coatings: Controls pigment flocculation and supports long-term storage stability.
