  • Best Practices for Elantas (Altana) EN-4 w/ EN-7

    *See Terms of Use Below

    1. Mixing

      Mix the EN-4 Part A component thoroughly with either the 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.
