Adhesives and Sealants Formulations with Polyurethane (PU) Resins

Polyurethane adhesives are known for their outstanding adhesion to diverse substrates, excellent abrasion resistance, remarkable flexibility across temperature ranges, and durability. Polyurethanes excel in applications like footwear assembly, automotive components, and construction applications. 

Types include one-component moisture-cure systems, two-component varieties, hot-melt polyurethanes, and specialized grades incorporate additional functionality like flame retardancy or enhanced chemical resistance. Recent innovations focus on bio-based polyurethanes incorporating renewable polyols supporting sustainability initiatives and growing development of low-isocyanate and isocyanate-free formulations addressing health concerns.
