Dow Acrysol DR1 Hydrophobic Alkali-Swellable Thickener

Dow Acrysol DR1 is a hydrophobic alkali-swellable thickener (HASE) from Dow’s Acrysol polymer series, delivering high shear viscosity, excellent sag resistance, and robust rheology control in waterborne coatings and architectural paints. It enables efficient thickening at low dosage, maintains stability across pH ranges, and enhances spatter resistance without compromising flow or leveling.
