Best Practices for Elantas (Altana) Conathane EN-20
-
Mixing
Mix individual components thoroughly before use, Mix Resin and Hardener in the ratio specified above until homogeneous. If hand mixing, degas at 1-5 mm Hg vacuum before use. Do not use paper or wooden containers or implements in mixing as they may introduce moisture into the system
-
Deairing/Degassing
If void-free castings are required for the particular application, degas the mixed system at 1-5 mm of mercury vacuum. Allow froth to rise and collapse, continue vacuum for 2-5 minutes. Containers should generally have twice the volume of mixed material to allow for frothing
-
Curing
The cure schedules above are based on time after the unit reaches the specified temperature and are recommendations only. The user is responsible for determining the optimum cure conditions for his application
Cure 7 days at 25°C / 77°F – or – 4 hours at 80°C / 176°F
