Q1: What makes Coapur TM 2025 different from conventional associative thickeners?
A: Coapur TM 2025 is a solvent-free, high-performance associative polyurethane thickener designed to deliver robust rheology control without volatile organic compounds. Its unique molecular architecture provides excellent shear-thinning behavior, superior film formation integrity, and enhanced compatibility with low-VOC and waterborne systems compared to many traditional HEUR thickeners.
Q2: Is Coapur TM 2025 suitable for use in architectural coatings and industrial maintenance paints?
A: Yes — it is widely used in interior and exterior architectural coatings, including flat and low-sheen formulations, where it imparts excellent sag resistance, brush/roller drag reduction, and spatter control. It also performs well in industrial maintenance paints requiring balanced flow and leveling with good post-application stability.
Q3: How should Coapur TM 2025 be incorporated into a formulation?
A: It is typically added during the let-down stage, after pigments and fillers are fully dispersed and pH has been adjusted. Pre-dilution with water or compatible co-solvent may aid uniform dispersion. Avoid high-shear addition directly to highly viscous phases; gentle mixing until homogeneous is recommended.
Q4: Does Coapur TM 2025 require neutralization or pH adjustment before use?
A: No — unlike some alkaline-swellable thickeners, Coapur TM 2025 is non-ionic and does not rely on pH activation. It functions effectively across a broad pH range (typically pH 4–11), offering greater formulation flexibility and reduced sensitivity to pH drift during storage or application.
