What is 2-methylimidazole?
2-Methylimidazole (CAS 693-98-1), commonly abbreviated as 2-MZ, is a heterocyclic amine used as a curing agent and catalyst in epoxy resin systems.
Where is 2-methylimidazole used?
- Electronics: curing agent for epoxy-based printed circuit board laminates
- Underfill compounds and encapsulants requiring precise Tg control
- Powder coatings: catalyst for epoxy-polyester hybrid systems, adjusting cure speed and flow
- Structural adhesives: incorporated into one-component epoxy systems requiring latent reactivity
- Pharmaceutical manufacturing: pH buffer and intermediate in synthesis of specialty imidazole derivatives
- Agrochemical manufacturing processes
- It accelerates crosslinking reactions at elevated temperatures.
Good to know: The material remains stable at room temperature but activates rapidly under heat.
Commercial specifications
- Technical grade standard; high-purity grades for electronics and specialty chemical applications
- Kilogram-scale bags through to bulk quantities
