  • Best Practices for Elantas (Altana) UC-51

    *See Terms of Use Below

    1. 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.

    2. Deairing/Degassing

      Degassing each component before mixing reduces the potential formation of air bubbles in the cast part.
