Best Practices for Elantas (Altana) Conathane EN-9 w/ Conathane EN-4
-
Mixing
Mix Conathane EN-4 Part A and Conathane EN-9 Part B together thoroughly at 25°-60°C using metal, plastic, or glass stirrers and containers. Degas the mixed material at 1-5mm of mercury and pour into molds at 25°-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.
