High-solids,water-based polyurethane resin

These waterborne polyurethane resins have solids contents of 48–59 wt%, depending on the grade, and are formulated without intentionally added amines. They are designed for applications in which processing efficiency, odor, VOC content, and coating performance are important. Grade-specific data on solids content, VOC content, processing conditions, odor evaluation, and coating performance are provided below. Product suitability should be evaluated for each formulation and under the intended processing and use conditions.
