Dow ACRYSOL RM-12W Thickener – Frequently Asked Questions (FAQ)

Q1: What is the primary function of ACRYSOL RM-12W in waterborne formulations?

A: ACRYSOL RM-12W is a hydrophobically modified ethoxylated urethane (HEUR) rheology modifier designed to provide mid-shear viscosity control, sag resistance, and excellent flow/leveling balance in water-based paints, coatings, and architectural finishes.

Q2: How does RM-12W differ from associative thickeners based on acrylic or cellulose chemistries?

A: Unlike traditional polyacrylate or cellulose thickeners, RM-12W functions through associative thickening—forming reversible physical networks via hydrophobic interactions. This delivers superior shear-thinning behavior, improved spatter resistance, and better compatibility with surfactants and co-solvents commonly found in modern low-VOC formulations.

Q3: Is RM-12W suitable for use in high-solids or low-VOC systems?

A: Yes—RM-12W is specifically engineered for performance in low-VOC and high-solids waterborne systems. Its non-ionic nature and low aqueous sensitivity support formulation stability and consistent viscosity development without compromising environmental compliance targets.

Q4: What is the recommended addition method for optimal performance?

A: RM-12W should be added during the let-down stage, typically after pigments and base binders are dispersed. Pre-dilution with water or compatible co-solvent (e.g., propylene glycol) is recommended to ensure uniform incorporation and avoid localized overdosing or viscosity spikes.

Q5: Does RM-12W require pH adjustment or specific storage conditions?

A: RM-12W is pH-stable across typical architectural coating ranges (pH 7–10) and does not require pH adjustment for activation. Store in original sealed containers at temperatures between 5 °C and 30 °C, avoiding freezing and prolonged exposure to direct sunlight.
