OMICURE® 24EMI is a liquid high temperature performance 2-Ethyl-4-Methyl Imidazole for use in filament winding, electrical laminates, coatings and laminating adhesives. OMICURE 24EMI is typically used at 1-3% as an accelerator for anhydrides or from 2-5% as the sole hardener for catalytic cures. This yields cured resins with better oxidation, aging and improved high temperature performance versus MDA.
