Storage Conditions

- Storage in original sealed Covestro container.

- Recommended storage temperature: 25 - 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 partially or fully at temperatures below 22 °C. However, careful melting at up to 50 °C will reliquify the product without any detrimental effect on its quality. A contact temperature of 80 °C must not be exceeded. The reliquified product must be homogenized as crystallization 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.
