Shelf Life Details Both the Part A and Part B components of CONATHANE® UC-54 are moisture sensitive. It is recommended that containers be flushed with dry nitrogen or CONAP® Dri-Purge each time the containers are closed., CONATHANE® UC-54, Part A and Part B have a shelf life of 12 months from date of manufacture, when stored in their original, unopened containers at 65°-85°F., Part A may crystallize in cooler temperatures. Crystallization is indicated by a light turbidity. Place the container in a 50°C oven for at least 4 hours to place the crystals back into solution. Agitate to assure complete uniformity. Cool to room temperature before use. Shelf Life Temperature (°F) 149 to 185 Shelf Life Type From date of manufacture Shelf Life (mon) 12 -

Best Practices for Elantas (Altana) UC-54
-
Application
CONATHANE® UC-54 has very good adhesion to most substrates and generally will not require the use of a primer. If adhesion improvement is necessary, contact Cytec Industries Inc. for specific recommendations. If the cast part is to be demolded after cure, apply a CONAP® mold release agent prior to casting.
Depending on mass and part configuration, CONATHANE® UC-54 can usually be demolded after curing 6 hours at room temperature. However, parts are extremely brittle at this stage and care should be exercised in removing parts from molds.
-
Mixing
Mix the two components together thoroughly at the recommended ratio at 25ºC stirring carefully to prevent air entrapment. If air entrapment is excessive, degas the mixture for 2-3 minutes at 1-5 mm of vacuum. Metal, glass, or plastic containers and stirring rods should be used. Avoid the use of wooden sticks and paper cups.
-
Deairing/Degassing
If air entrapment is excessive, degas the mixture for 2-3 minutes at 1-5 mm of vacuum.
