General Characterization
Desmodur® VP.PU 3230 is a mixture of diphenylmethane-4,4'-diisocyanate (MDI) with isomers and homologues of higher functionality used for the production of the flexible polyurethane cold-curing HR molded foam for automotive seating.
Storage Conditions
Recommended storage temperature (°C): 20 - 40
Shelf life (ex works)
6 months if stored in sealed, moisture-tight containers
Partially used containers should be tightly resealed due to the nature of the product.
Recommended temperature for processing (°C): 20 - 25
Lengthy storage leads to an increase in the viscosity of Desmodur® VP.PU 3230, although in our experience this has no adverse effect on the processing.
