ACRYSOL™ Rheology Modifiers

ACRYSOL™ Rheology Modifiers: Shear Genius

Color trends may come and go, but rheology makes a lasting impression on consumer paint preference. How the paint feels when it’s stirred, poured and applied to the wall creates a signature experience that helps define and enhance your brand.

History of Innovation
Dow introduced the paint and coatings industry to associative thickening with ACRYSOL™ HASE and HEUR Rheology Modifiers. Now we’re taking rheology to new performance levels with ACRYSOL™ RM-400 and ACRYSOL™ RM-995. These next-generation KU builders support near-zero-VOC targets while offering breakthrough sag/flow balance, no-drip sag resistance, excellent flow and leveling, higher film build and uniformity, and improved viscosity stability upon tinting (vs. conventional HEUR technology).

  • 1980 :Dow introduces associate thickening.
  • 1990 : Dow launches solvent-free ACRYSOL™ HEURs.
  • 2000 : Dow develops DESIGNED RHEOLOGY™ HASEs to replace HEC
  • 2010 : Dow invests ACID SUPRESSION™ Technology for easy-pouring HEURs with no added surfactant.
  • 2013: Dow launches new family of easy-pouring, high-performance HEURs with breakthrough sag/flow balance.

Ranges of Shear
ACRYSOL™ Rheology Modifiers offer low-, mid- and high-shear solutions that adapt to changing shear rates. They offer a broad range of thickeners to help you achieve your brand’s formulation goals and VOC targets.

How It Works

HEURs are highly efficient KU builders but must be manufactured with added solvent or surfactant to reduce as-supplied viscosity to manageable levels. ACID SUPPRESSION™ Technology developed by Dow eliminates the need for added solvent or surfactant. Instead, these easy-to-pour HEURs employ pH-triggered association and thickening. The trigger is “off” at low pH and “turns on” at paint pH. This facilitates low viscosity (< 2000 cP) in the as-supplied product and full-thickening efficiency in the paint formulation without the addition of solvent or surfactant.
