一般特征

Monomeric cycloaliphatic diisocyanate.
In the manufacture of polyisocyanates and polyurethanes.

储存条件

- 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 temperatures of approx. 25 °C and below can result in crystallization and appropriate settling at the bottom. This solidification is reversible by briefly heating the product without adversely affecting the quality of the product. Our recommendation in that case is warming the product to 40 - 50°C and homogenization before use.
