Q1: What types of resins is EASAQUA D 803 compatible with?
A: EASAQUA D 803 is specifically designed for use with waterborne polyurethane dispersions (PUDs) and acrylic emulsions. It provides efficient crosslinking in ambient- or low-bake-cure systems and demonstrates good compatibility with both anionic and weakly cationic dispersions.
Q2: How does EASAQUA D 803 contribute to film performance?
A: Upon curing, it enhances key mechanical properties including scratch resistance, chemical resistance, and block resistance—particularly in high-solids, low-VOC coatings. The resulting films also show improved mar resistance and durability under humid conditions.
Q3: What is the recommended addition method and storage guidance?
A: Add EASAQUA D 803 to the formulation during the let-down stage, under gentle agitation, at pH 7–9. Avoid prolonged exposure to temperatures above 40 °C. Store in original sealed containers at 5–25 °C; protect from freezing and direct sunlight.
Q4: Is EASAQUA D 803 suitable for food-contact or regulated applications?
A: EASAQUA D 803 is not pre-approved for direct food-contact applications. Formulators must conduct full regulatory evaluation—including migration testing and compliance verification—based on final cured film composition, end-use conditions, and applicable regional requirements.
