Storage Conditions

- Storage in original sealed Covestro container.

- Recommended storage temperature: 15 - 25 °C.
Temperatures higher than30 °C should be avoided.

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

General information: The product is sensitive to temperatures below + 10°C. Temperatures below to + 10 °C can damage the product irreversibly. Prolonged storage at higher temperatures may affect the product properties. Containers must be kept sealed and protected from direct sunlight as otherwise the evaporation of water will result in the formation of a non-redispersible polymer film. After extended storage time sedimentation can occur. The material can be proceeds without quality losses after homogenization.
