Q1: What is the primary application field for DAOTAN VTW 1686/40WA?
A: DAOTAN VTW 1686/40WA is a waterborne polyurethane dispersion designed primarily for high-performance industrial coatings, including flexible and semi-rigid topcoats for synthetic leather, technical textiles, and functional laminates where durability, abrasion resistance, and low-temperature flexibility are required.
Q2: Is DAOTAN VTW 1686/40WA compatible with other resin systems?
A: Yes, it demonstrates good compatibility with selected acrylic dispersions and certain crosslinkers commonly used in waterborne systems. However, compatibility testing under actual formulation conditions—including pH, ionic strength, and shear history—is strongly recommended before full-scale integration.
Q3: How should DAOTAN VTW 1686/40WA be stored and handled?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, avoiding freezing and prolonged exposure to direct sunlight or excessive heat. Stir gently before use to ensure homogeneity; do not dilute with hard water or high-ionic-strength solutions without prior evaluation.
Q4: Does this resin require post-crosslinking for optimal performance?
A: While DAOTAN VTW 1686/40WA offers good film integrity and mechanical properties in its self-crosslinking form, enhanced chemical resistance and thermal stability can be achieved using appropriate ambient- or heat-activated crosslinkers—particularly in demanding end-use applications.
