DESMODUR E 23

DESMODUR E 23 is an aromatic polyisocyanate prepolymer based on diphenylmethane diisocyanate (MDI). It contains 15.4% NCO and has a viscosity of 1800 mPa.s at 23°C. DESMODUR E 23 is suitable as a binder for moisture-curing one-component systems and as a hardener for hydroxyl-bearing co-reactants. When thinned with solvent, it can be used as primers and sealers for porous substrates, providing protection against moisture, oil, fuel and chemicals. It also works as a binder in synthetic resin mortars. Coatings made with DESMODUR E 23 are used as high-grade anti-corrosion systems for steel in engineering applications, delivering tough yet flexible and wear-resistant coatings. DESMODUR E 23 also enables the formulation of solvent-free moisture-curing one-component adhesives or two-component adhesives for bonding various materials.
