Features Of Dow Acrysol DR50 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 compared to conventional ASSF thickeners.

  3. Offers robust rheology control across a broad pH range (pH 7.5–10.5) after neutralization.

  4. Enables low-splatter, high-transfer efficiency spray application with reduced sagging on vertical surfaces.

  5. Imparts outstanding freeze-thaw stability and long-term storage viscosity retention in architectural and industrial formulations.

Typical Applications Of Dow Acrysol DR50 Hydrophobic Alkali-Swellable Thickener

  1. Interior and exterior architectural latex paints.

  2. Waterborne industrial maintenance coatings.

  3. Low-VOC and zero-VOC decorative wall coatings.

  4. Textured coatings and elastomeric finishes.

  5. Stain-blocking primers and high-hiding basecoats.
