Q1: What type of rheology does RM3030 provide in waterborne formulations?
A: RM3030 is a hydrophobically modified ethoxylated urethane (HEUR) associative thickener that delivers strong pseudoplastic (shear-thinning) flow behavior, providing excellent sag resistance at rest and good application properties under shear.
Q2: Is RM3030 compatible with high-shear mixing and common paint manufacturing processes?
A: Yes — RM3030 is designed for robust performance during high-shear dispersion and post-addition in both let-down and mill-base stages. It exhibits good stability in the presence of surfactants, co-solvents, and typical pigment dispersants used in architectural and industrial coatings.
Q3: How should RM3030 be added to a formulation for optimal performance?
A: RM3030 is typically added as a post-additive to the finished formulation, either neat or pre-diluted with water or compatible solvent. For best results, add slowly with moderate agitation and allow sufficient time for full associative network development before final viscosity adjustment or packaging.
Q4: Does RM3030 require pH adjustment or neutralization prior to use?
A: No — unlike alkali-swellable thickeners (ASE), RM3030 is non-ionic and functions independently of pH. It performs consistently across a broad pH range (typically pH 4–10) without requiring neutralization or buffering agents.
Q5: What are key handling and storage recommendations for RM3030?
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 during handling, and ensure equipment is clean and free of incompatible residues before use.
