Best Practices for Elantas (Altana) UC-51
-
Mixing
Mix the Part B to ensure uniform distribution of the filler.
Mix the two-components together thoroughly at the 1:1 volumetric ratio at 25ºC.
-
Deairing/Degassing
Degassing each component before mixing reduces the potential formation of air bubbles in the cast part.
