Q1: What type of rheology does RM-2020NPR provide in aqueous systems?
A: RM-2020NPR is a hydrophobically modified ethoxylated urethane (HEUR) associative thickener that delivers pseudoplastic (shear-thinning) rheology, offering excellent flow and leveling at low shear while maintaining sag resistance and viscosity stability at rest.
Q2: Is RM-2020NPR compatible with common surfactants and co-solvents used in architectural coatings?
A: Yes — RM-2020NPR exhibits good compatibility with nonionic and anionic surfactants, as well as typical co-solvents such as glycol ethers and alcohols. However, formulation screening is recommended to confirm performance in specific systems containing high levels of ionic surfactants or strong solvents.
Q3: How should RM-2020NPR be incorporated into a water-based formulation?
A: It is typically added during the let-down stage, after pigment dispersion and under moderate agitation. Pre-dilution with water or a compatible solvent may improve dispersion uniformity. Avoid high-shear addition directly to highly ionic or low-pH phases without prior evaluation.
Q4: Does RM-2020NPR require neutralization or pH adjustment for activation?
A: No — unlike alkali-swellable thickeners (ASE), RM-2020NPR is a non-ionic HEUR thickener and does not rely on pH for thickening performance. Its associative mechanism functions across a broad pH range (typically pH 4–10), though extreme pH values may affect long-term stability.
Q5: What are key handling and storage considerations for RM-2020NPR?
A: Store in original sealed containers at temperatures between 5°C and 30°C, protected from freezing and prolonged exposure to direct sunlight. Avoid contamination with incompatible materials; always follow Dow’s Safety Data Sheet (SDS) for safe handling, personal protection, and disposal guidance.
