FEM-EMZCHEMICAL NAME 2-Ethyl-4-Methylimidazole STRUCTURAL FORMULA MOLECULAR FORMULA C6H10N2 MOLECULAR WEIGHT 110.16 CAS NO. 931-36-2 PROPERTY - Low viscosity and low volatility, easy to handle at room
temperature.
- Medium-temperature curing imidazole catalyst, with a curing
temperature range of 60–150°C.
- Excellent compatibility with epoxy resins and effective at low
addition levels.
- The cured material offers good heat resistance, mechanical
strength, and electrical insulation properties.
- Stable during long-term storage; if crystallization occurs, it can
be restored by heating without affecting performance.
APPLICATIONS - Epoxy resin curing agent / accelerator: used in potting, casting,
laminating, adhesives, insulating varnishes, and powder coatings.
- Synthetic intermediate: used in pharmaceuticals, pesticides, dyes,
and organic synthesis catalysts.
- Electronic packaging: used for insulation and protection of
semiconductors, coils, and PCB boards.
