Features Of Dow Acrysol DR72 Hydrophobic Alkali-Swellable Thickener

  1. Delivers high mid-shear viscosity and excellent flow/leveling balance in waterborne coatings.

  2. Provides superior resistance to water, surfactants, and electrolytes due to hydrophobic modification.

  3. Enables robust rheology control across wide pH range (pH 7–10) with minimal sensitivity to alkaline neutralization variations.

  4. Offers low foaming characteristics and good compatibility with common co-thickeners and associative thickeners.

  5. Improves sag resistance on vertical surfaces without compromising brushability or spray atomization.

Typical Applications Of Dow Acrysol DR72 Hydrophobic Alkali-Swellable Thickener

  1. Interior and exterior architectural latex paints.

  2. Textured coatings and elastomeric wall systems.

  3. Primer and sealer formulations for masonry and drywall.

  4. Low-VOC and zero-VOC decorative coatings.

  5. Industrial maintenance coatings requiring water resistance and film integrity.
