Storage Conditions

-Store in original, tightly sealed Covestro containers
- Recommended storage temperature: 5° - 23° C (41° - 73° F). Temperatures higher than 30° C (86° F) should be avoided.
- Protect from direct sunlight, freezing temperatures, excessive heat and foreign material contamination.
General information: This product is sensitive to freezing temperatures as they can cause irreversible damage. Prolonged storage at higher temperatures may adversely affect the product's properties and also cause sedimentation or coagulation. Containers must be kept sealed and protected from direct sunlight, otherwise water evaporation will result in the formation of a non-redispersible film. Contamination with certain bacteria, fungi or algae may render the product unusable.
