Logistics and Handling

Storage Conditions

– Storage in original sealed Covestro container.

– Recommended storage temperature: 0 – 30 °C.

– Protect from moisture, heat and foreign material.

General information: Hydrophilic isocyanates are very moisture-sensitive and react with water to form carbon dioxide and insoluble ureas. The containers must always be kept tightly closed. The accessof water in all forms (moist air, solvents, moist containers) must be prevented, because the generation of carbon dioxide can lead todangerous increases in pressure. Storage at higher temperatures will result in increase of color and viscosity.
