Q1: What is the primary function of Desmophen 1652 in waterborne coating systems?
A: Desmophen 1652 functions as a reactive polyol component in two-component waterborne polyurethane systems, contributing to film formation, flexibility, and chemical resistance while enabling low-VOC formulations.
Q2: Is Desmophen 1652 compatible with common waterborne isocyanate hardeners?
A: Yes, it is specifically designed for use with aliphatic water-dispersible isocyanates—such as HDI- and IPDI-based polyisocyanates—and exhibits good compatibility and reactivity under standard ambient curing conditions.
Q3: How does Desmophen 1652 support sustainability goals in industrial coatings?
A: As a waterborne polyester polyol, it enables formulators to significantly reduce solvent content versus solvent-borne alternatives, supporting compliance with evolving VOC regulations and lowering the environmental footprint of high-performance protective and decorative coatings.
Q4: What are typical storage and handling recommendations for this resin?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from freezing and prolonged exposure to direct sunlight or moisture. Prior to use, ensure thorough mixing to maintain homogeneity, especially after extended storage.
