Shelf Life Details CONATHANE® EN-2550, Part A and Part B, should be stored at temperatures of 65-85°F in tightly closed containers. If containers are opened and the contents only partially used, the container should be flushed with dry nitrogen (see CONAP® Dri-Purge) or dry air before being resealed. If crystallization has occurred, heat the components(s) to 140°F(60°C) and mix well to re-liquefy. Stabilize component(s) to room ambient temperature (or selected pre-heat temperature) prior to use.;The shelf life of EN-2550, Part A and Part B, is one 18 months from date of manufacture when stored in the original unopened container. Shelf Life Temperature (°F) 65 to 85 Shelf Life Type From date of manufacture Shelf Life (mon) 18 -

Best Practices for Elantas (Altana) Conathane EN-2550
-
Mixing
The two components should be mixed thoroughly in metal or glass containers using metal or glass stirrers. Degassing of the mixed material should be accomplished at room temperature to 60°C at 1 to 5 mm Hg vacuum. Containers should be large enough to allow for frothing during degassing. Any material or container that could introduce water into the system should be avoided.
Metal molds should be coated with a mold release agent such as CONAP® MR-5002.
