Shelf Life Details	The shelf life of CONATHANE EN-4 Part A, EN-7 Part B, and EN-8 Part B is15 months from date of manufacture when stored in the original unopened containers 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) before resealing to prevent waste of material.
Shelf Life Temperature (°F)	70 to 84
Shelf Life Type	From date of manufacture
Shelf Life (mon)	15

Best Practices for Elantas (Altana) EN-4 w/ EN-7

*See Terms of Use Below
1. Mixing
  
  Mix the EN-4 Part A component thoroughly with either the EN-7 Part B or the EN-8 Part B at 25°C-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-100°C. Containers should be large enough to allow for volume expansion during the degassing cycle. Any material or container that could introduce moisture into the system should be avoided.
