The Chemistry of Waterborne Polyurethane Coatings

Polyurethanes have long been known to produce coatings that exhibit high toughness, abrasion resistance, enhanced aesthetics, and durability. Solvent-based polyurethanes have traditionally set the performance standard for high durability coatings. However, environmental considerations for low-VOC alternatives and reduced exposure to solvents have stimulated the development of alternative technologies based on waterborne polyurethane systems.
