Storage (Use) Precautions
WANNATE HMDI is a clear, transparent liquid. Due to its active chemical properties, it is easy to react with water to form insoluble urea compounds and release carbon dioxide, causing drums and viscosity increases. Therefore, it is necessary to ensure that the container is strictly dry and sealed and filled with dry nitrogen for protection during storage. Stored in a closed container, it can be stored for at least nine months, maintaining the above-mentioned performance indicators, and the quality will not decrease.
At temperatures below 25°C, WANNATE HMDI may partially crystallize and precipitate to the bottom In case of this situation, the product must be heated to 40-50°C and shaken before use.
