Q1: What is the primary function of VYLONAL MD-1930 in waterborne coating formulations?
A: VYLONAL MD-1930 functions as a reactive crosslinker and film-forming aid, enhancing hardness, chemical resistance, and substrate adhesion in waterborne polyester-based coatings—particularly for industrial and decorative applications requiring low VOC content.
Q2: Is VYLONAL MD-1930 compatible with common waterborne acrylic or polyurethane dispersions?
A: Yes, it demonstrates good compatibility with many waterborne acrylics and anionic/cationic polyurethane dispersions. However, pre-testing in the final formulation is recommended to confirm stability, pot life, and cure performance under specific conditions.
Q3: What curing conditions are typically required for optimal performance?
A: Full crosslinking generally occurs at elevated temperatures (e.g., 120–160 °C), though ambient-cure capability may be achieved over extended time when combined with appropriate catalysts. Cure profile depends on film thickness, substrate, and co-resin selection.
Q4: How should VYLONAL MD-1930 be stored and handled to maintain stability?
A: Store in original sealed containers at 5–30 °C, away from freezing and direct sunlight. Avoid prolonged exposure to high humidity or strong oxidizing agents. The resin is supplied as a stable aqueous dispersion and does not require special solvents for handling.
