Logo and REACH application
The technical information of this product is only valid if it is consistent with the latest version of the corresponding «Chemical Safety Data Sheet». Any updates to safety-related information – as required by relevant regulations – are only reflected in the «Chemical Safety Data Sheets», copies of which will be revised and distributed. Please refer to the currently valid «Chemical Safety Data Sheet» for current classification, identification, application and process methods and other safety technical information.

 

Operation guide
Like all isocyanates, Desmodur 0118 Liquid is very sensitive to water and reacts with water to produce insoluble urea and carbon dioxide. In a closed container, the carbon dioxide produced can cause a dangerous rise in container pressure. Exposure of Desmodur 0118 Liquid to air, especially sunlight, will accelerate its yellowing. It is therefore recommended to store Desmodur 0118 Liquid in a dry nitrogen atmosphere. Yellowing generally does not affect the workability of the product. Desmodur 0118 Liquid is heat sensitive and will form dimers.
Further information on physical and chemical properties can be found in the Safety Data Sheet.
