Storage Conditions
- Storage in original sealed Covestro containers.
- Recommended storage temperature: >0 - 40°C
- Protect from frost, heat and foreign material.
General information: The product is sensitive to frost. Prolonged freezing can 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.
