General Characterization

Crelan EF 403 is a cycloaliphatic polyuretdione without blocking agent.
It is suitable as a hardener for polyurethane powder coatings.

Storage Conditions

Crelan EF 403 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. The product is sensitive to moisture. Storage at higher temperatures will result in agglomeration of the product. This agglomeration is reversible by mechanical stress without adversely affecting the quality of the product. Recommended storage temperature is -5 to 40°C. Additionally, we recommend that the piling up of the pallets should be avoided.
