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
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.
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.
If air entrapment is excessive, degas the mixture for 2-3 minutes at 1-5 mm of vacuum.
