Best Practices for Elantas (Altana) EN-4 w/ EN-8
-
Mixing
Mix the CONATHANE EN-4 Part A component thoroughly with either the CONATHANE EN-7 Part B or the EN-8 Part B at 25°C - 40°C using metal, plastic, or glass stirrers and containers. Degas the mixed material at 1-5 mm of mercury and pour into molds at 25°C -100°C. Containers should be large enough to allow for volume expansion during the degassing cycle. Any material or container that could introduce moisture into the system should be avoided.
