It is suitable for use in the formulation of moisture-curing one-component polyurethane coatings.

Storage Conditions

Desmodur E XP 2605/1 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. The product is sensitive to moisture and heat and should therefore be stored in its sealed original containers in a cool place. During storage, the viscosity of one-component polyurethane coatings may increase slightly. This process is accelerated by elevated temperatures but has no effect on the mechanical properties of the paint films. Recommended storage temperature is 0º-30ºC.
