Desmodur IL 1351 is an aromatic polyisocyanate based on toluene diisocyanate (TDI). Properties / Applications: Desmodur IL 1351 is used as the hardener component for fast drying two-component polyurethane coatings. When combined with certain Desmophen® products, Desmodur IL 1351 yields very fast-drying systems. Such systems are used in the furniture industry where very short drying times and early sandability are required. As with any product, use of Desmodur IL 1351 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
