Features Of Spredox D-161 Dispersant

  1. High-efficiency steric stabilization for inorganic pigments and fillers in aqueous systems.

  2. Excellent compatibility with acrylic, styrene-acrylic, and vinyl acetate-based emulsions.

  3. Low foaming profile, minimizing process interference during high-shear dispersion and grinding.

  4. pH-stable performance across 5.0–9.5, ensuring formulation robustness under varied conditions.

  5. Non-ionic character provides low sensitivity to electrolytes and enhanced shelf-life stability.

Typical Applications Of Spredox D-161 Dispersant

  1. Architectural waterborne paints and coatings.

  2. Industrial maintenance coatings for metal and concrete substrates.

  3. Water-based printing inks (e.g., flexographic and gravure).

  4. Construction chemicals including tile adhesives and cementitious grouts.

  5. Functional pigment dispersions for specialty colorants and masterbatches.
