Business Information

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
