Storage Conditions

Desmodur I should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. The product is sensitive to moisture.

This solidification is reversible by briefly heating the product without adversely affecting the quality of the product. Recommended storage temperature 0º-30ºC.
