Q1: What is the primary application of DAOTAN VTW 1237/32WANMP in polyurethane systems?
A: DAOTAN VTW 1237/32WANMP is a waterborne polyurethane dispersion designed primarily for high-performance industrial coatings and overprint varnishes where excellent film formation, flexibility, and chemical resistance are required — especially on flexible substrates such as paper, board, and certain plastics.
Q2: Is this resin compatible with common waterborne acrylic or polyester dispersions?
A: Yes, DAOTAN VTW 1237/32WANMP exhibits good compatibility with many standard waterborne acrylic and polyester dispersions, enabling hybrid formulations that balance hardness, toughness, and gloss. Compatibility should be verified experimentally in the final formulation due to sensitivity to pH, ionic strength, and surfactant systems.
Q3: How should DAOTAN VTW 1237/32WANMP be stored and handled to maintain stability?
A: Store in tightly sealed containers at temperatures between 5 °C and 30 °C, avoiding freezing and prolonged exposure to direct sunlight or excessive heat. Stir gently before use to ensure homogeneity, and avoid contamination with incompatible solvents or highly acidic/basic materials that may destabilize the dispersion.
Q4: Can this resin be crosslinked with external agents to enhance performance?
A: Yes, DAOTAN VTW 1237/32WANMP can be effectively crosslinked using suitable water-dispersible polyisocyanates or aziridine-based crosslinkers to improve chemical resistance, mar resistance, and thermal stability — particularly in demanding topcoat applications.
