ACRYSOL™ RM-845

ACRYSOL™ RM-845 Rheology Modifier is a new generation, solvent-free, APEO-free, non-ionic product. ACRYSOL™ RM-845 is based upon patented and proprietary technology that enables it to contain 27% solids yet be provided at a low viscosity to allow facile pumping and pouring. ACRYSOL RM-845 Rheology Modifier builds mid-shear Stormer viscosity more efficiently than existing KU-builders. It is recommended for acrylic- and styrene/acrylic-based latex coating formulations. ACRYSOL™ RM-845 Rheology Modifier offers excellent flow and leveling, as well as gloss development, for both interior and exterior paints. It imparts a rheological profile to architectural and industrial coatings very similar to that of ACRYSOL RM-825, but with the benefit of no added solvent, allowing for ultra-low VOC formulations.

Formulation Information
  • ACRYSOL RM-845 Rheology Modifier is best added under good mixing conditions to ensure complete incorporation into the formulation. ACRYSOL RM-845 should be used cautiously in applications below pH 8 because of a decrease in thickening efficiency at such lower pH’s.
  • ACRYSOL RM-845 is supplied at low pH and therefore can slightly lower the pH of the paint formulation to which it is added. Small amounts of extra base may need to be added to the paint formulation to ensure that the final pH target is reached.
