General Information
This product is sensitive to moisture and heat. It should be protected from contact with atmospheric moisture. Higher storage temperatures for longer periods of time may cause discoloration or the formation of insoluble deposits. The product crystallizes at temperatures below 18°C. However, careful melting at temperatures up to 50°C will allow the product to re-solidify without any adverse effect on its quality. Contact surface temperature must not exceed 80°C. The reliquefied product must be homogenized because crystallization causes a change in the isomer ratio between the crystalline phase and the stationary liquid phase. Open containers must be resealed after product has been removed. If stored for long periods of time, product should be covered with nitrogen. The product reacts with water to release carbon dioxide. During storage, transfer and handling of the product, any form of contact with water (moist containers, aqueous solvents, moist air) must be prevented, as the production of carbon dioxide can lead to a dangerous increase in pressure. The polyurea formed at the same time may cause turbidity. They can also cause blockage and damage to filters, pumps and pipes.

Storage time
We represent that, for a period of twelve months after the date of shipment specified in the corresponding shipping document, the Products will conform to the specifications or values ​​set forth in the “Specifications or Characteristics Data” section above, Whenever applicable, the Products are stored in full compliance with the storage conditions described and referenced in the “Storage” section above and are otherwise properly handled. Failure during the twelve month period does not necessarily mean that the product no longer meets specifications or setpoints. However, before using the above products, we recommend testing the product if it still meets the specifications or set values. We make no representations about the product after the twelve month period and we are not responsible for any failure of the product to meet specifications or settings after the twelve month period.
