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., Store below 25°C / 77°F in a dry controlled environment out of direct sunlight. This material should be suitable for use stored under these conditions in the original sealed containers for twelve (12) months from the date of shipment. Shelf Life Temperature (°F) 70 to 85, <77 Shelf Life Type From date of manufacture, From the date of shipment Shelf Life (mon) 0, 12 -

Best Practices for Elantas (Altana) Conathane EN-4 w/ Conathane EN-12
-
Mixing
Mix individual components thoroughly before use.
CONATHANE® EN-4 Part A may crystallize upon storage or during shipment. If this has occurred, heat to 60°C, mix thoroughly, and cool to room temperature before processing.
Components may be preheated up to 60°C if reduced viscosity is required. If hand mixing, degas at >27 in. Hg vacuum before use.
-
Curing
The user is responsible for determining the optimum cure conditions for his application.
