When it comes to high-quality polyurethane applications, Desmodur® polyisocyanates from Covestro are renowned for their versatility. Along with Covestro polyols, they are a key component for the production of exceptional polyurethane-based products with wide-ranging properties.

Our comprehensive range of Desmodur® polyisocyanates for flexible and rigid foams, binders, integral skin foams, composites, solventborne and high solids polyurethane (PU) coatings, adhesives and sealants offers tremendous formulating freedom. PUs based on Desmodur® are used in upholstery, mattresses, car seats, thermal insulation (buildings, refrigeration), wheels, rollers and dashboards. They are also used as coatings to protect everyday products such as cars, trucks and buses, appliances and electronics, wood furniture and cabinetry, interior and exterior walls, floors, window frames, food packaging and, not least, marine vessels, bridges and other infrastructure. In addition, Desmodur® makes it possible to optimize adhesives with a wide range of high-performance building blocks.
