Business Information

Shelf Life Details	Storage and Handling: CONATHANE® EN-2527, 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.;The shelf life of EN-2527, Part A and Part B, is 18 months from date of manufacture when stored in the original unopened containers a temperatures of 65-85°F. Part B of EN-2527 is highly filled with a special filler which has a tendency to settle to the bottom of the containe Generally, this is a soft settlement that can be brought back into suspension by agitation or rolling on a paint roller.;The low vapor pressure of the CONATHANE? EN-2527 system greatly reduces the vapor hazard and toxicity as compared to TDI (toluene diisocyanate) and TDI prepolymers.
Shelf Life Temperature (°F)	149 to 185
Shelf Life Type	From date of manufacture
Shelf Life (mon)	18
