  • Best Practices for Elantas (Altana) UC-41

    *See Terms of Use Below

    1. Application

      CONATHANE® UC-41 may be processed by hand or by machine.

      CONATHANE® UC-41 has very good adhesion to most substrates and generally will not require the use of a primer. If adhesion improvement is necessary, contact Cytec Industries Inc. for specific recommendations. If the cast part is to be demolded after cure, apply a CONAP® mold release agent prior to casting. Castings can generally be demolded in 4 hours at room temperature

    2. Mixing

      Mix the two components thoroughly at 25°C in the recommended mix ratio. Stir carefully to prevent entrapment of air.

    3. Deairing/Degassing

      If stirring is done carefully degassing of the mixed material may not be necessary. If air entrapment is excessive, degas the mixture for 1 to 1 2 minutes at 1-5 mm of vacuum.
