Features Of Dow OROTAN CA-2500 Dispersant

  1. High-efficiency polymeric dispersant designed for stable pigment and filler suspension in water-based systems.

  2. Excellent wetting and deflocculation performance across a broad range of inorganic pigments and extenders.

  3. Low foaming character ensures compatibility with high-shear mixing and airless spray application processes.

  4. pH-stable over 6.0–10.0, enabling robust formulation flexibility without viscosity drift or precipitation.

  5. Non-ionic architecture minimizes sensitivity to electrolytes and enhances freeze-thaw stability in coatings.

Typical Applications Of Dow OROTAN CA-2500 Dispersant

  1. Architectural interior and exterior latex paints.

  2. Industrial maintenance coatings for metal and concrete substrates.

  3. Water-based wood stains and clear finishes.

  4. Printing inks for flexible packaging and paper applications.

  5. Construction adhesives and cementitious tile grouts.
