Q1: What is the primary function of DAOTAN VTW 6460/35WA in waterborne polyurethane systems?
A: DAOTAN VTW 6460/35WA is a water-dispersible polyurethane resin designed primarily as a crosslinker or reactive modifier to enhance film hardness, chemical resistance, and mechanical durability in aqueous PU coatings and adhesives.
Q2: Is DAOTAN VTW 6460/35WA compatible with common waterborne acrylic dispersions and hybrid systems?
A: Yes — it exhibits good compatibility with a broad range of waterborne acrylics, vinyl acetate copolymers, and hybrid polymer dispersions, enabling formulation flexibility for high-performance topcoats and laminating adhesives.
Q3: How should DAOTAN VTW 6460/35WA be incorporated into formulations?
A: It is typically added during the final stage of dispersion mixing under mild agitation, at ambient temperature. Pre-dilution with deionized water may aid uniform incorporation, and pH adjustment (generally within 7.5–9.0) is recommended to maintain colloidal stability.
Q4: Does this resin require thermal curing, or can it achieve full performance at ambient conditions?
A: While ambient crosslinking occurs over time, optimal film properties—including solvent resistance and tensile strength—are achieved through moderate thermal curing (e.g., 80–120 °C for 10–30 minutes), depending on film thickness and substrate.
