*This data is general information and is not part of the product description.

Storage   Stored in original sealed containers.
    Recommended storage temperature: 18-40 C.
    Avoid moisture, heat and foreign substances.
    General information: The product is sensitive to moisture and heat. Contact with water in the atmosphere should be avoided. Long-term storage at higher temperatures may lead to discoloration or formation of insoluble precipitates. The product will crystallize partially or completely below 15 degree C. However, when heated carefully at up to 50 degree C, the product will be liquefied again without any adverse effects on product quality. The contact temperature shall not exceed 80 C. Because crystallization results in a change in the proportion of isomers between the crystalline phase and the liquid phase, the re-liquefied product must be homogenized. After taking out the product, the open container must be re-sealed. If stored for a long time, the product should be protected by nitrogen. The product reacts with water to release carbon dioxide. During the storage, transmission and treatment of products, because the generation of carbon dioxide may increase the risk of pressure, any form of contact with water (wet containers, aqueous solvents, wet air) must be prevented. Urea formed at the same time may cause turbidity. They can also cause blockage and damage to filters, pumps and pipes.
Storage time   Cosmic declares that the product meets the requirements of the above-mentioned "storage" clause and is properly handled within 12 months from the date of shipment specified in the transport document, in accordance with the above-mentioned "specification or characteristic value" clause. Specification or characteristic values specified (applicable as appropriate).
If the product exceeds the 12-month period mentioned above, it does not mean that it no longer meets the set values in specifications or characteristic values. However, Cox proposes to test products that have been shipped for more than 12 months prior to use to confirm that they still meet the set values in specifications or characteristic values. Kosichuan does not undertake any commitments for products over 12 months from the date of shipment, nor does it assume any responsibility or obligation for the set values of its non-conforming specifications or characteristics.
Security   Product data tables are only valid when used in conjunction with their corresponding latest security data tables. Any security-related information updates - as required by regulations - will only be reflected in the security data sheet and copies will be revised and distributed accordingly. For relevant information, including the latest classification and labeling, applications, processing methods and more security-related data, please refer to the current effective security data sheet.
Supplementary information   The product is mainly used as hardener or coating material adhesive. Processing polyisocyanate and residual monomer TDI containing active coating materials or adhesives requires appropriate protection measures mentioned in the safety data sheet. Therefore, these products may only be used in industrial or industrial applications. They are not suitable for home worker (DIY) applications.
