Shelf Life Details The component parts of these systems are storage stable for 15 months from date of manufacture in the original, unopened containers when stored at temperatures of 70°F-85°F. If containers are opened and the contents only partially used, containers should be flushed with dry nitrogen (see CONAP® Dri-Purge) or dry air before resealing to prevent waste of material. Shelf Life Temperature (°F) 70 to 85 Shelf Life Type From date of manufacture Shelf Life (mon) 15 -

Best Practices for Elantas (Altana) Conathane EN-11 w/ Conathane EN-4
-
Mixing
Thoroughly mix the EN-4 Part A with either the EN-11 Part B or EN-12 Part B at 25°C to 40°C using metal, plastic, or glass stirrers and containers. Degas the mixed material at 1-5 mm of mercury and pour into molds at 25°C-80°C. Containers should be large enough to allow for volume expansion during the degassing cycle. Any material or container that could introduce moisture in the system should be avoided.
