Desmodur® N 3800 is a solvent free flexibilizing aliphatic polyisocyanate. In combination with suitable polyols, it can be used in the formulation of highly flexible coatings that are stable to accelerated and outdoor weathering. These can be used for coating plastics. The use of Desmodur® N 3800 as a combination hardener component makes it possible to adjust the flexibility of the polyol mill base. The product can also be used as a flexibilizing component in other applications, e.g. stone-chip protection systems, vehicle repair systems.
