Q1: What is the primary application area for ALBERDINGK U 9700?
A: ALBERDINGK U 9700 is primarily designed for high-performance waterborne coatings and inks requiring excellent film integrity, flexibility, and chemical resistance — especially in industrial wood, plastic, and metal finishing applications where low VOC content and good substrate adhesion are critical.
Q2: Is ALBERDINGK U 9700 compatible with common waterborne acrylic or epoxy dispersions?
A: Yes, ALBERDINGK U 9700 exhibits good compatibility with many standard waterborne acrylic dispersions and certain modified epoxy emulsions. Compatibility should be verified empirically in the final formulation, as performance may vary depending on pH, ionic strength, and surfactant systems used.
Q3: How does ALBERDINGK U 9700 contribute to film formation and mechanical properties?
A: As a self-crosslinking waterborne polyurethane resin, U 9700 enhances film cohesion, tensile strength, and abrasion resistance without requiring external crosslinkers. It forms continuous, resilient films upon coalescence and ambient or mild thermal curing, delivering improved scratch resistance and elasticity compared to conventional acrylic dispersions.
Q4: Can ALBERDINGK U 9700 be used in formulations targeting food-contact compliant coatings?
A: ALBERDINGK U 9700 is not pre-certified for direct food contact. Its suitability for such applications depends entirely on the full formulation, processing conditions, and compliance verification against applicable regional regulations — end users must conduct thorough migration testing and regulatory assessment before claiming food-contact compliance.
