General Characterization
Monomeric cycloaliphatic diisocyanate, using alternative feedstocks attributed via mass balance (ISCC PLUS certified).
For the manufacture of the polyisocyanates and polyurethanes.
For the manufacture of the polyisocyanates and polyurethanes.
Storage Conditions
- Storage in original sealed Covestro container.
- Recommended storage temperature: 0 - 30 °C.
- Protect from moisture, heat and foreign material.
General information: The product is sensitive to moisture. Storage at higher temperatures will result in increase of color and viscosity. Storage at significant lower temperatures will result in solidification. This solidification is reversible by briefly heating the product without adversely affecting the quality of the product.
Additional information regarding safe handling, transport and storage from isocyanates can be found in the guidelines from the ISOPA association.
