Q1: What is the primary application area for DAOTAN TW7000W?
A: DAOTAN TW7000W is specifically engineered as a waterborne polyurethane dispersion for high-performance, low-VOC industrial coatings—particularly where excellent flexibility, abrasion resistance, and adhesion to challenging substrates (e.g., plastics, treated metals, and composites) are required. It is commonly used in protective topcoats for automotive trim, electronics enclosures, and premium furniture finishes.
Q2: Can DAOTAN TW7000W be blended with other waterborne resins or crosslinkers?
A: Yes, DAOTAN TW7000W demonstrates good compatibility with selected acrylic dispersions, waterborne alkyds, and common water-reducible crosslinkers such as aziridine or carbodiimide types. Compatibility and film formation should always be verified in the final formulation under intended drying conditions.
Q3: How does DAOTAN TW7000W perform in terms of water and chemical resistance after curing?
A: When properly formulated and fully cured, films based on DAOTAN TW7000W exhibit good resistance to water immersion, mild alkaline cleaners, and common solvents encountered in industrial handling—though extended exposure to strong acids, bases, or polar aprotic solvents may affect performance. Final resistance depends significantly on film thickness, cure schedule, and co-resin selection.
Q4: Is DAOTAN TW7000W suitable for use in coatings requiring FDA-compliant or food-contact-safe formulations?
A: DAOTAN TW7000W is not pre-qualified for direct food contact applications. While it is free of intentionally added heavy metals and APEOs, its suitability for regulated end uses must be evaluated case-by-case by the formulator—including full compliance testing against applicable regional food-contact regulations.
