Q1: What is the primary function of Eastman AQ-65S in coating and ink formulations?
A: Eastman AQ-65S is a water-dispersible polyester resin designed to enhance film formation, improve substrate adhesion, and contribute to gloss and flexibility in water-based coatings and inks—particularly for flexible packaging and paper applications.
Q2: Is Eastman AQ-65S compatible with common water-based acrylic or styrene-acrylic dispersions?
A: Yes, Eastman AQ-65S is generally compatible with many waterborne acrylic and styrene-acrylic dispersions. Compatibility should be confirmed through lab-scale evaluation under intended processing conditions, as performance may vary depending on pH, ionic strength, and surfactant systems.
Q3: How does Eastman AQ-65S contribute to heat sealability in packaging coatings?
A: Eastman AQ-65S imparts thermoplastic character to coatings, enabling cohesive film softening at elevated temperatures. This supports effective heat sealing without requiring additional tackifiers or plasticizers in many formulations.
Q4: Can Eastman AQ-65S be used in food-contact compliant formulations?
A: Eastman AQ-65S is manufactured without intentionally added bisphenol A, phthalates, or heavy metals. While it is suitable for use in food-contact applications where permitted by local regulatory requirements, final compliance depends on the full formulation, processing conditions, and applicable jurisdictional regulations.
Q5: What is the recommended approach for incorporating Eastman AQ-65S into a water-based system?
A: Eastman AQ-65S is typically added during the let-down stage under moderate agitation. It is stable across a broad pH range (approximately 6–9) and can be incorporated directly into aqueous dispersions without pre-dilution, though gradual addition helps ensure uniform dispersion.
