Fantasy to Rheology Imagine a paint with perfect flow and make it real with ACRYSOL™ RM-400 or ACRYSOL™ RM-995 Rheology Modifiers. These next-generation KU builders are powered by ACID SUPPRESSION™ Technology to offer more of what you need to make a lasting paint impression, including breakthrough sag-flow balance, no-drip sag resistance, and higher film build and uniformity that facilitates better applied hide. Featuring low as-supplied viscosity, these high performance HEURs are easy to pour and mix during paint formulation. They contain no added solvent or surfactant, making them an excellent choice for meeting low and ultra-low VOC targets.

Broad Spectrum Benefits

Key Features• Excellent KU efficiency• Excellent sag-flow balance• No-drip sag resistance

White/Pastel BasesIn white and pastel bases, improved sag resistance with excellent flow offers thicker, more uniform applied films that facilitate improved applied hiding.

Medium/Deep TintsIn medium to deeply tinted bases – generally those containing 4% or more of colorant – reduced sensitivity to viscosity loss upon the addition of colorants enhances end-use application and feel.

Performance Profile

Deep Tints In deep tint bases, improved sag resistance carries through to the final tinted paint, facilitating noticeably better appearance upon application by either brush or roller.

• Robust color development & stability• Improved viscosity stability on tinting • Improved roller application

• Low as-supplied viscosity• No added solvent or surfactant• Ultra-low VOC capable

Enabling TechnologyHigh-efficiency, ultra-low VOC capable ACRYSOL™ Rheology Modifiers feature ACID SUPPRESSION™ Technology. This Dow innovation employs pH-triggered association and thickening to facilitate easy-pouring HEURs with no added solvent or surfactant. 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.

At low pH, cations repel and reduce association.

At high pH, neutral amines allow full

association.
