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.

Best Practices for Elantas (Altana) Conathane EN-2527
-
Application
At room temperature, a good pouring viscosity (18,800 cps) of a 400 gram mass is maintained for about 20 minutes. Metal molds should be coated with a CONAP® mold release agent.
-
Mixing
The two components should be mixed thoroughly in metal or glass containers using metal or glass stirrers.
-
Deairing/Degassing
Degassing of the mixed material should be accomplished at room temperature 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.
