– Protects against moisture, heat and foreign objects.

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 crystallized at temperatures below 18°C. However, careful melting at temperatures up to 50°C will re-solidify the product without any adverse effect on its quality. The 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. Opened containers must be resealed after product removal. For long-term storage, the product should be covered 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 (wet containers, aqueous solvents, humid air) must be prevented, since the generation of carbon dioxide may lead to a dangerous increase in pressure. Simultaneously formed polyurea may cause haze. They can also cause clogging and damage to filters, pumps and pipes.

Storage time
We declare that within twelve months after the date of shipment stated in the corresponding shipping document, the product will conform to the specifications or values ​​stated in the “Specification or characteristic data” section above, Where applicable, the product is stored in full compliance with the storage conditions described and referenced in the “Storage” section above and otherwise handled with care. 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 that they be tested if they still meet the specifications or set values.
