Operation suggestions
Like all isocyanates, Desmodur TP . PU 0129 M 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.

Storing raw materials in an environment above 30°C will accelerate the formation of dimers and shorten the shelf life of the product.
Storing Desmodur TP. PU 0129 M in a crystalline or partially crystallized state will also relatively accelerate the formation of dimers, and this state should also be avoided. If not much dimer is produced, the crystallized product can still be used by melting it quickly. But please note that the melting temperature is between 60 to 70℃. The temperature at which the product is heated cannot exceed 70°C. Once melting is complete, the product must be homogenized and cooled down to the recommended temperature for storage. Since this treatment will inevitably produce more dimers, it is recommended to use the product as soon as possible. If air enters, especially if the product is exposed to light for a long time, it will cause contamination, yellowing, etc. of the product.
