Storage Conditions
- Storage in original sealed Covestro container.
- Recommended storage temperature: 10 - 30 °C.
- Protect from moisture, heat and foreign material.
General information: The product is sensitive to moisture and should therefore be stored in its sealed original containers. Storage at higher temperatures may result in an increase in viscosity and at lower temperatures in the formation of crystalline deposits.
Detailed information on safe handling, transport and storage of isocyanates is given in the guidelines of the ISOPA association.
