General Characterization

Desmophen® 41WB09 is a reactive polyether triol with high polyoxyethylene content. It is not miscible with most polyether polyols (e.g. Arcol® Polyol 1374).

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.
