Storage Conditions
- Storage in original sealed Covestro containers.
- Recommended storage temperature: 5 - 30 °C.
- Protect fromfrost , heat and foreign material.
General information: An increase in viscosity may occur during storage. If the containers are not sealed properly, the evaporation of water will result in the formation of a film which cannot be redispersed. 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.
