DOW ROHMHAAS Acrysol RM-2050D Thickener – Frequently Asked Questions (FAQ)
Q1: What is the primary thickening mechanism of Acrysol RM-2050D?
A: Acrysol RM-2050D is a hydrophobically modified ethoxylated urethane (HEUR) associative thickener. It functions by forming transient physical networks in aqueous systems through hydrophobic associations between polymer chains and surfactants or other hydrophobic domains, providing efficient rheology control and enhanced sag resistance.
Q2: Is RM-2050D compatible with high-shear processes and common paint manufacturing equipment?
A: Yes, RM-2050D exhibits good shear stability and is designed for robust performance during high-speed dispersing, grinding, and letdown operations typical in architectural and industrial coating production. Its associative nature allows viscosity recovery post-shear, supporting consistent application properties.
Q3: How does RM-2050D perform in low-VOC and zero-VOC formulations?
A: RM-2050D is well-suited for low- and zero-VOC waterborne systems, as it requires no co-solvents for activation and delivers effective thickening without compromising VOC compliance. Its performance remains stable across a broad pH range and in the presence of common electrolytes found in modern eco-friendly formulations.
Q4: What are typical dosage guidelines for RM-2050D in architectural coatings?
A: Dosage depends on formulation requirements and target viscosity, but RM-2050D is typically used at low concentrations—generally ranging from 0.1% to 2% by weight of the total formulation—to achieve desired flow and leveling behavior while maintaining storage stability.
