It is widely used in various applications, including as a protective coating for wood surfaces, where it enhances appearance and durability. Polyurethanes are created by combining diisocyanates and polyols, resulting in a range of products from flexible foams to rigid plastics. Most polyurethanes are classified as thermosetting polymers, meaning they do not melt upon heating.5 Sources
