Q1: What is the primary function of DAOTAN VTW 6462/36WA in polyurethane coatings?
A: DAOTAN VTW 6462/36WA is a waterborne polyurethane dispersion designed to enhance film formation, flexibility, and mechanical durability in high-performance topcoats—particularly where balanced hardness, scratch resistance, and low-temperature application are required.
Q2: Is this resin compatible with common crosslinkers used in industrial wood or plastic coatings?
A: Yes, DAOTAN VTW 6462/36WA is formulated for compatibility with standard aqueous crosslinkers such as aziridine, carbodiimide, and blocked isocyanate types—enabling improved chemical resistance and cure performance without compromising storage stability.
Q3: Can it be used in low-VOC or solvent-free coating systems?
A: Absolutely. As a waterborne polyurethane resin, DAOTAN VTW 6462/36WA supports the development of low-VOC and near-zero-solvent formulations, aligning with evolving environmental regulations and sustainability goals for decorative and functional coatings.
Q4: How does it perform under humid or low-temperature curing conditions?
A: This resin exhibits robust film-forming capability across a broad temperature and humidity range, supporting reliable coalescence and crosslinking even at ambient conditions as low as 10 °C and relative humidity up to 80%, making it suitable for diverse production environments.
