Best Practices for Elantas (Altana) UC-49
-
Mixing
Thoroughly mix the two components together at the recommended ratio. Stir carefully at 25°C to prevent entrapment of air. If air entrapment is excessive, degas the mixture for 2-3 minutes at 1-5 mm of vacuum. If mixing and stirring is done carefully, degassing of the mixed material may not be necessary.
