Logo and REACH application
The technical information of this product is valid only if it is consistent with the corresponding latest version of the "Safety Data Sheet for Chemicals". Any updates to safety-related information – as required by relevant regulations – are only reflected in the «Safety Data Sheet», copies of which will be revised and distributed. Please refer to the currently valid «Safety Data Sheet» for current classification, labeling, application and processing 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 will cause the pressure of the container to rise and cause danger. Desmodur 0118 Liquid Exposure to air, especially sunlight, will accelerate its yellowing. It is therefore recommended to store Desmodur 0118 Liquid in liquid form under a dry nitrogen atmosphere. Yellowing generally does not affect the processability of the product. Desmodur 0118 Liquid is heat sensitive and forms dimers.
  More information on physical and chemical properties can be found in the Safety Data Sheet.
