Features Of Dow ACRYSOL DR73 Hydrophobically modified alkali Swellable Thickener

  1. Delivers high mid-shear viscosity for excellent sag resistance in vertical applications.

  2. Provides outstanding rheology control and spatter resistance in low-VOC, high-solids architectural coatings.

  3. Offers superior compatibility with common co-thickeners, surfactants, and biocides in waterborne systems.

  4. Enables efficient thickening at low dosage levels due to hydrophobic association and alkali activation.

  5. Maintains stable viscosity across a broad pH range (pH 8.0–10.5) after neutralization.

Typical Applications Of Dow ACRYSOL DR73 Hydrophobically modified alkali Swellable Thickener

  1. Interior and exterior latex paints.

  2. Textured decorative coatings and plasters.

  3. Primer and masonry coatings.

  4. Low-odor and zero-VOC architectural coatings.

  5. Water-based wood stains and clear finishes.
