Polyurethane, commonly abbreviated PU, is any polymer consisting of a chain of organic units joined by urethane (carbamate) links. Polyurethane polymers are formed through step-growth polymerization by reacting a monomer containing at least two isocyanate functional groups with another monomer containing at least two hydroxyl (alcohol) groups in the presence of a catalyst. Polyurethane formulations cover an extremely wide range of stiffness, hardness, and densities.
Polyurethane coatings can provide a thin film, high-gloss finish with exceptional weathering performance characteristics. Polyurethane coatings are used across virtually all industry segments to provide a smooth durable finish that has superior resistance to corrosion, abrasion, and chemical exposure.
