DESMODUR E 15 is an aromatic polyisocyanate prepolymer based on toluene diisocyanate. It provides medium viscosity and reactivity for applications. DESMODUR E 15 offers NCO content of 4.4% and viscosity of 7,000 mPa.s well suited for its uses. It can be combined with other chemicals to form highly reactive two-component systems yielding highly flexible and crack-bridging coatings on surfaces. DESMODUR E 15 also produces one-component systems when combined with latent hardeners, suitable for coating flat exteriors maintaining flexibility. Its storage stability and compatibility with common solvents adds to ease of processing for different product formulations without compromising performance.
