Labeling and REACH Application
The technical information of this product is valid only 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 – will only be reflected in the Safety Data Sheet, copies of which will be revised and distributed. For current classification, labeling, application and process methods and other safety technical information, please refer to the currently valid “Safety Data Sheet for Chemicals”.
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 in the container to rise and cause danger. Desmodur 0118 Liquid will accelerate its yellowing when exposed to air, especially sunlight. Therefore, it is recommended to store Desmodur 0118 Liquid in a dry nitrogen environment. Yellowing generally does not affect the processability of the product. Desmodur 0118 Liquid is sensitive to heat and will form dimers.
For more information about physical and chemical properties, you can check the security data list.
