Storage Conditions
- Storage in original sealed Covestro container.
- Recommended storage temperature: 0 - 25 °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 high temperatures will lead to an increase in viscosity and a reduction of the NCO content.
