  • Best Practices for Elantas (Altana) Conathane EN-2521

    *See Terms of Use Below

    1. Mixing

      The two components should be mixed thoroughly in metal or glass containers using metal or glass stirrers. Degassing of the mixed material should be accomplished at room temperature to 60°C at 1-5 mm Hg vacuum. Containers should be large enough to allow for frothing during degassing. Any material or container that could introduce water into the system should be avoided.
