Dow Acrysol DR-180 Associative Alkali-Swellable Thickener

Dow Acrysol DR-180 is a high-performance associative alkali-swellable thickener (AST) from Dow’s Acrysol polymer series. It delivers excellent rheology control, viscosity build, and sag resistance in waterborne coatings and architectural paints. Compatible with anionic surfactants and stable across pH 7–10, it enhances flow/leveling while minimizing spatter and brush drag—ideal for low-VOC, high-solids formulations.

Features Of Dow Acrysol DR-180 Associative Alkali-Swellable Thickener

  1. Delivers high mid-shear viscosity for excellent sag resistance and brush/roller drag in architectural coatings.

  2. Provides superior flow and leveling while maintaining robust spatter resistance in waterborne formulations.

  3. Offers exceptional compatibility with surfactants, co-thickeners, and common paint additives.

  4. Delivers consistent rheology performance across a broad pH range (pH 7.5–10.5) after neutralization.

  5. Enables low VOC and zero APEO formulations without compromising thickening efficiency or stability.

Typical Applications Of Dow Acrysol DR-180 Associative Alkali-Swellable Thickener

  1. Interior and exterior architectural flat and low-sheen latex paints.

  2. Textured decorative coatings and plaster-based finishes.

  3. Waterborne primers and undercoats requiring controlled rheology.

  4. Industrial maintenance coatings for metal and masonry substrates.

  5. Acrylic-based sealers and clear topcoats where clarity and film integrity are critical.
