ACRYSOL™ RM-400 Rheology Modifier

Solvent-free*, hydrophobically modified ethylene oxide urethane (HEUR) rheology modifier based on proprietary technology for an excellent balance of properties. This KU-building associative thickener offers formulators an excellent balance of sag resistance, particularly in tinted paints, flow and leveling, and gloss development for interior and exterior paints. Contributes significant ICI viscosity, allowing the reduction of ICI builder use level in the paint. When reformulating with ACRYSOL™ RM-400, the ICI builder concentration should be reduced approximately 25% as a starting point. Should be added under good mixing conditions to ensure complete incorporation into the formulation. Supplied at low pH and, therefore, may slightly lower the pH of the paint formulation. Small amounts of extra base may need to be added to the paint formulation to ensure the final pH target is reached. We recommend that all base be added prior to the addition of ACRYSOL RM-400.

Uses:

  • Interior and exterior paints
  • Wide range of sheen through high gloss paints, including low-VOC formulations
  • Water-based architectural and industrial coatings
