About Us

Container: MDI-50 is a clear liquid at room temperature. It turns yellow when exposed to light and air. by

Due to its active chemical properties, it is easy to react with water to generate insoluble urea compounds and emit carbon dioxide

Drum and increase viscosity. Therefore, in the storage process, it is necessary to ensure that the container is strictly dry sealed and filled with dry nitrogen protection.

Storage temperature: MDI-50 can generate dimer insoluble matter with the extension of storage time, please at 25ºC ~ 35

Store in the range of ºC.

Melting conditions: If the storage temperature of MDI-50 is lower than 17 ° C, crystallization will occur. must

The crystals are heated and melted immediately in the shortest possible time. Local overheating is strictly prohibited, as the product will decompose and produce at more than 230 ° C

Produce gas. It is recommended to use a hot air oven equipped with a barrel rolling device to bake at 60ºC. After drying, the materials in the barrel must be mixed

It's even. In the process of barrel drying, the supporting point of the barrel should be carefully paid attention to to prevent leakage caused by wear and collision.
