Storage Conditions

- Storage in original sealed Covestro container.

- Recommended storage temperature: 10 - 25 °C.

- Protect from direct sunlight, frost, heat and foreign material.

General information: The product is sensitive to frost. Freezing can cause irreversible damage to the product. Extended storage at higher temperatures can impair product properties and leads ultimately to an elevated risk of sedimentation or coagulation.
Containers must be kept sealed and protected from direct sunlight as otherwise the evaporation of water will result in the formation of non-redispersible polymer particles. Contamination with certain bacteria, fungi or algae can render the product unusable.
