Storage Conditions

- Storage in original sealed Covestro containers.

-
Recommended storage temperature: 5 - 30 °C.

-
Protect from frost, heat and foreign material.

General information: Because slight sedimentation may occur during storage, homogonize thoroughly (e.g. by stirring) prior to removing product. If the containers are not kept well closed, a non-redispersible film is formed as a result of the evaporation of water. The product is sensitive to frost. Freezing will damage the product irreversibly. Prolonged storage at higher temperatures may result in a decrease of viscosity and/or an increase of average particle size, possibly resulting in sedimentation or coagulation. Contamination with certain bacteria, fungi or algae may render the product unusable.
