- 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.
