Desmodur E 744 is an aromatic polyisocyanate prepolymer based on diphenylmethane-diisocyanate (MDI). Properties / Applications: Desmodur E 744 prepolymer can be combined with a variety of different polyols to produce two-component coatings that have good toughness and elasticity. These coatings can be used as high solids or solvent-free systems in application areas such as membranes, deck coatings, pipe coatings, roof coatings, binders, encapsulants, product finishing, or coatings for solvent-sensitive substrates such as polystyrene foams and other plastic materials. As with any product, use of Desmodur E 744 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
