General Characterization
DESMOPHEN® 2450 X, based on glycerine as branching component, is a highly viscous, slightly yellowish liquid at ambient temperature. It is used to manufacture either semi-rigid polyurethane slabstock foams or foams with enhanced hardness.
Storage Conditions
Recommended storage temperature (°C): 20 - 35
Shelf life (ex works)
12 months if stored in sealed, moisture-tight containers
Partially used containers should be tightly resealed due to the hygroscopic nature of the product.
Recommended temperature for processing (°C): 20 - 25.
