Q1: What is the primary function of DAOTAN VTW 1262/35WA in polyurethane coatings?
A: DAOTAN VTW 1262/35WA is a waterborne polyurethane dispersion designed to enhance film formation, flexibility, and mechanical durability in low-VOC, high-performance coatings—particularly where balanced hardness and elongation are required.
Q2: Is this resin compatible with common crosslinkers used in industrial waterborne PU systems?
A: Yes, DAOTAN VTW 1262/35WA is formulated for compatibility with standard aqueous crosslinkers such as blocked isocyanates and aziridines, enabling robust two-component (2K) performance when needed for improved chemical resistance or cure speed.
Q3: Can it be blended with acrylic dispersions or other polymer emulsions?
A: Yes, DAOTAN VTW 1262/35WA exhibits good coalescence behavior and is commonly blended with acrylic dispersions to tailor film properties—such as balancing gloss, scrub resistance, and low-temperature flexibility—without compromising colloidal stability in properly formulated systems.
Q4: What are typical storage and handling recommendations?
A: Store in tightly sealed containers at temperatures between 5 °C and 30 °C, avoiding freezing and prolonged exposure to direct sunlight. Prior to use, stir gently to ensure homogeneity; avoid high-shear mixing that may destabilize the dispersion.
