Storage Conditions

- Storage in original sealed Covestro container.

- Recommended storage temperature: 10 - 25 °C.

- Protect from frost, heat and foreign material.

General information: This product is sensitive to frost, and must be protected from cold. Frozen product is irreversibly damaged. Containers must be kept sealed as otherwise the evaporation of water will result in the formation of a non-redispersible film. Due to the process, the product can tend toward subsequent creaming. This manifests in the form of a very thin, brown layer which after some time becomes visible on the surface of the product. Prior homogenization of the product using a suitable stirrer is recommended each time product is removed from the container.
