Q1: What is the primary function of DAOTAN VTW 1250/40WA in polyurethane systems?
A: DAOTAN VTW 1250/40WA is a water-dispersible polyurethane resin designed to act as a reactive crosslinker or modifier, enhancing film formation, flexibility, and chemical resistance in aqueous two-component PU coatings and adhesives.
Q2: Is DAOTAN VTW 1250/40WA compatible with common aqueous polyisocyanate hardeners?
A: Yes, it is formulated for compatibility with standard aliphatic aqueous polyisocyanate dispersions, supporting stable mixing and controlled reaction kinetics under typical ambient curing conditions.
Q3: How should DAOTAN VTW 1250/40WA be stored to maintain stability?
A: Store in tightly sealed original containers at temperatures between 5 °C and 30 °C, protected from freezing and prolonged exposure to direct sunlight or excessive heat to preserve dispersion integrity and reactivity.
Q4: Can this resin be used in low-VOC or solvent-free formulations?
A: Yes — as a water-based polyurethane resin, DAOTAN VTW 1250/40WA supports the development of low-VOC and high-solids aqueous PU systems without requiring organic co-solvents for stabilization.
