Coatex Coapur XS 71 Thickener – Frequently Asked Questions (FAQ)
Q1: What type of rheology does Coatex Coapur XS 71 provide?
A: Coapur XS 71 delivers associative thickening with pronounced pseudoplastic (shear-thinning) behavior, offering excellent flow and leveling at low shear while maintaining sag resistance and suspension stability at rest.
Q2: Is Coapur XS 71 compatible with anionic and nonionic surfactants commonly used in architectural coatings?
A: Yes, Coapur XS 71 exhibits broad compatibility with common anionic and nonionic surfactants, making it well-suited for waterborne architectural paints and decorative coatings without compromising viscosity stability or film formation.
Q3: How should Coapur XS 71 be incorporated into a formulation?
A: It is typically added during the let-down stage, dispersed directly into water or pre-diluted with water or co-solvent. Efficient high-shear mixing is recommended to ensure complete hydration and optimal performance.
Q4: Does Coapur XS 71 offer good freeze-thaw stability in formulated systems?
A: When properly formulated, Coapur XS 71 contributes to improved freeze-thaw stability in water-based systems due to its polymeric structure and associative network resilience—though final performance depends on overall formulation balance and stabilizer selection.
