store
- Store in original Covestro airtight containers.
- Recommended storage temperature: 10-25℃
- Avoid freezing, high temperature and foreign substances.
General Information: This product is sensitive to freezing and must be protected from freezing. Freezing will cause irreversible damage to the product. The container must remain airtight, otherwise evaporation of moisture will result in the formation of a non-redispersible polymer film. Due to this process, the product has a tendency to stratify and it is recommended to first homogenize the product with a suitable stirrer for each sampling.
storage time
Covestro declares that the product complies with the above "specification or characteristic values" for a period of 6 months from the date of shipment stated on the shipping document, provided that the product is stored in full compliance with the requirements in the "Storage" clause above and handled properly Specifications or characteristic values stated in the Terms (as applicable).
The fact that a product exceeds the above 6-month period does not mean that it no longer meets the specifications or the set values in the characteristic values. However, Covestro recommends that products older than 6 months from the date of shipment be tested before use to confirm that they still meet the specifications or set values in the characteristic values. Covestro makes no commitments for products older than 6 months from the date of shipment and accepts no responsibility or liability for non-conformance to specifications or set values in characteristic values.
