Allgemeine Charakterisierung
Desmodur 15 (Naphthylene-1,5-diisocyanate) flakes are a white to yellowish substance. The molecular weight of Desmodur 15 is 210 g/mol and it is used for the production of Vulkollan®.
Lagerungsbedingungen
Desmodur 15 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. Desmodur 15 is sensitive towards moisture and reacts with water to form urea derivatives and carbon dioxide. Desmodur 15 should therefore be stored in tightly sealed containers in a cool, dry place. Containers which have been opened must be tightly resealed each time material is removed. Recommended storage temperature is less than 30ºC.
