Dow ACRYSOL RM-2020 NPR Thickener – Frequently Asked Questions (FAQ)
Q1: What type of rheology does RM-2020 NPR provide in aqueous systems?
A: RM-2020 NPR is a hydrophobically modified ethoxylated urethane (HEUR) thickener that delivers associative rheology—providing strong pseudoplastic flow behavior, good sag resistance, and enhanced leveling in waterborne coatings and architectural paints.
Q2: How should RM-2020 NPR be incorporated into a formulation?
A: It is typically added during the let-down stage, after pigment grinding, under moderate agitation. Pre-dilution with water or co-solvent (e.g., propylene glycol) is recommended to ensure uniform dispersion and avoid localized over-thickening.
Q3: Is RM-2020 NPR compatible with common surfactants and co-binders used in acrylic emulsion paints?
A: Yes—it exhibits broad compatibility with nonionic and anionic surfactants, as well as common acrylic, vinyl acetate, and styrene-acrylic emulsions. However, performance may vary with high levels of strongly ionic additives or low-HLB surfactants; lab-scale compatibility testing is advised.
Q4: Does RM-2020 NPR require pH adjustment for optimal performance?
A: Unlike alkali-swellable thickeners (ASE), RM-2020 NPR is not pH-sensitive and performs consistently across a wide pH range (typically pH 6–10), making it suitable for both neutral and mildly alkaline formulations without requiring pH stabilization.
