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.
