Dow Acrysol DR-73 Associative Alkali-Swellable Thickener

Dow Acrysol DR-73 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 paints and coatings. Compatible with acrylics, vinyl acetate, and styrene-butadiene systems, it enhances flow/leveling while maintaining shear-thinning behavior and long-term stability without requiring high pH adjustment.
