Storage (Use) Precautions

  Container: Fresh product WANNATE ^® MDI-100 The melt is a clear transparent liquid. Due to its active chemical properties, it is very easy to react with water to generate insoluble urea compounds and release carbon dioxide, causing the drum to swell and increase viscosity. Therefore, during storage, it is necessary to ensure that the container is strictly dry and sealed and filled with dry nitrogen protection. Temperature: WANNATE ^® MDI-100 With the extension of storage time, insoluble dimer may be generated, and its generation rate varies with temperature. Therefore, the storage temperature of the solid WANNATE ^® MDI-100 should be as low as possible, and it should be stored below 0 °C. The storage temperature of the heated liquid WANNATE ^® MDI-100 is 44 °C～ 46 °C, and it should be used up as soon as possible.

Shelf Life

From the date of production, under the specified storage conditions, the shelf life of the solid WANNATE ^® MDI-100 is 3 months. If the product still meets this technical specification after inspection, it can still be used after the expiration date; the liquid supplied by tank truck WANNATE ^® MDI-100 under dry nitrogen protection , is 10 days.
