Q1: What is the primary function of DAOTAN TW 6436/40WANMP in polyurethane systems?
A: DAOTAN TW 6436/40WANMP is a waterborne polyurethane dispersion designed to serve as a film-forming binder or reactive modifier, enhancing flexibility, adhesion, and mechanical durability in coatings and adhesives—particularly where low-VOC and aqueous processing are required.
Q2: Is this resin compatible with common crosslinkers used in industrial PU coatings?
A: Yes, DAOTAN TW 6436/40WANMP is formulated to be compatible with standard aqueous crosslinkers such as aziridine, carbodiimide, and certain blocked isocyanates—though compatibility and cure performance should always be verified experimentally within the final formulation.
Q3: Can it be used in direct food-contact applications?
A: DAOTAN TW 6436/40WANMP is not pre-certified for direct food contact. Its suitability for such applications depends on full regulatory assessment of the final cured film—including extraction behavior, migration potential, and compliance with applicable regional frameworks—and requires validation by the end-user’s regulatory team.
Q4: How does storage temperature affect its stability and shelf life?
A: For optimal stability, store between 5 °C and 30 °C in tightly sealed containers, away from freezing and prolonged exposure to elevated temperatures. Extended storage outside this range may accelerate viscosity changes or phase separation, reducing usable shelf life.
