Features Of Dow ACRYSOL DR50 Hydrophobically modified alkali Swellable Thickener

  1. Delivers excellent rheology control in high-shear and low-shear conditions for balanced application and leveling performance.

  2. Provides superior water resistance and scrub resistance in formulated coatings due to hydrophobic association network formation.

  3. Offers outstanding compatibility with common co-thickeners, surfactants, and biocides used in architectural and industrial coatings.

  4. Enables efficient thickening at low dosage levels (typically 0.2–0.6% active) with rapid viscosity development upon pH adjustment.

  5. Maintains stable viscosity across wide temperature and freeze-thaw cycles without significant degradation.

Typical Applications Of Dow ACRYSOL DR50 Hydrophobically modified alkali Swellable Thickener

  1. Interior and exterior architectural latex paints.

  2. Textured coatings and elastomeric wall coatings.

  3. Industrial maintenance coatings and protective topcoats.

  4. Water-based primers and sealers.

  5. Stain-blocking and high-hiding flat/matte finishes.
