General Characterization

Mondur TD 80 toluene diisocyanate is a mixture of 2,4 and 2,6 isomers in the ratio of 80/20.

Storage Conditions

Mondur TD 80 diisocyanate must be stored in tightly closed containers and protected from moisture and foreign materials. TDI will react slowly with water to form polyureas and liberate carbon dioxide gas, which may cause sealed containers to expand and rupture. Storage temperatures should be controlled at 21° to 43°C (70° to 110°F) to maintain product quality. For extended periods, it is recommended that a temperature range of 25° to 35°C (77° to 95°F) be maintained.
The shelf life is twelve months after receipt of material by customer, when stored in sealed original containers under conditions stated above.
