Allgemeine Charakterisierung
Desmodur® T 65 N is a mixture of 2,4-toluene diisocyanate [A] and 2,6-toluene diisocyanate [B]. Desmodur® T 65 N is used for the production of polyurethanes.
Lagerungsbedingungen
- Storage in original sealed container.
- Recommended storage temperature: 18 - 40°C.
- Protect from moisture, heat and foreign material.
General information:
The product is sensitive to moisture and heat. It should be protected against contact with atmospheric moisture. Higher storage temperatures for prolonged periods may result in discoloration or the formation of insoluble deposits. The product crystallizes at temperatures below 18°C. However, careful melting at up to 50°C will reliquify the product without any detrimental effect on its quality. The contact surface temperature may not exceed 80°C. The reliquified product must be homogenized as crystallisation causes a shift in the isomer ratio between the crystalline and the still liquid phases.
Opened containers must be resealed after removing product. If stored for long periods, the product should be overlaid with nitrogen. The product reacts with water to release carbon dioxide. During storage, transfer and handling of the product, contact with water in any form (damp containers, solvents containing water, moist air) must be prevented as the generation of carbon dioxide may result in a dangerous increase in pressure. The polyureas which are formed at the same time may result in turbidity. They may also cause blockages and breakdowns in filters, pumps and pipes.
Storage time:
We represents that, for a period of twelve months following the day of shipment as stated in the respective transport documents, the product will meet the specifications or values set forth in section "specifications or characteristic data" above, what ever is applicable, provided that the product is stored in full compliance with the storage conditions set forth in and referenced under section "storage" above and is otherwise handled appropriately.
