Shelf Life Details CONATHANE EN-2553 Part A and Part B should be stored at temperatures of 20ºC-30ºC (68ºF-86ºF) in tightly closed containers. If containers are opened and the contents only partially used, they should be flushed with dry nitrogen (CONAP® Dri-Purge) or dry air before being resealed.;The shelf life of CONATHANE EN-2553 Part A and Part B is 18 months from date of manufacture in the original unopened containers., 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) 68 to 86, <77 Shelf Life Type From date of manufacture, From the date of shipment Shelf Life (mon) 18, 12 -

Best Practices for Elantas (Altana) Conathane EN-2553
-
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 40ºC (104ºF) at 1-5 mm of mercury 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
Mix and degas individual components thoroughly prior to use. CONATHANE® EN-2553 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.
-
Mixing
Mix the EN-2553 Part A and EN-2553 Part B in the ratio specified above until homogeneous. Components may be preheated up to 60°C if reduced viscosity is required. If hand-mixing, degas at >27 in. Hg before use.
-
Curing
Cure 7 days at 25°C / 77°F – or – 16 hours at 80°C / 176°F.The cure schedules above are based on time after the unit reaches the specified temperature and are recommendations only. The user is responsible for determining the optimum cure conditions for his application
