Q1: What is the primary function of NeoRez U-371 in waterborne coating formulations?
A: NeoRez U-371 is a self-emulsifying, anionic aliphatic polyurethane dispersion designed to enhance film formation, flexibility, and mechanical durability in waterborne architectural, industrial, and protective coatings—particularly where improved scrub resistance and low-temperature coalescence are required.
Q2: Can NeoRez U-371 be blended with acrylic dispersions or other common latexes?
A: Yes, NeoRez U-371 exhibits good compatibility with many acrylic, styrene-acrylic, and vinyl acetate-based dispersions, enabling hybrid systems that balance cost, performance, and regulatory compliance—though compatibility testing under specific formulation conditions is recommended prior to full-scale implementation.
Q3: Is NeoRez U-371 suitable for use in low-VOC or zero-VOC coating systems?
A: Yes, NeoRez U-371 is supplied as a water-based dispersion with negligible VOC content and no added organic solvents or APEOs, making it well-suited for formulating compliant low-VOC architectural and maintenance coatings targeting major regional environmental standards.
Q4: How should NeoRez U-371 be stored and handled to maintain stability?
A: Store in tightly sealed containers at temperatures between 5 °C and 30 °C, away from freezing conditions and direct sunlight. Avoid prolonged exposure to high shear or extreme pH shifts during processing, as these may affect colloidal stability.
