Imidazole curing agents are a type of curing agents developed in recent years.。Imidazole compounds as new curing agents and accelerators for epoxy resin，unique：No high temperature curing required，Because its curing mechanism is similar to that of tertiary amines，It is anionic catalytic polymerization，But there is no chain transfer like tertiary amines that require high temperature curing.，So medium temperature curing is enough。The cured product has a high heat distortion temperature，Other properties are roughly the same as those of aromatic amine curing agents.。The alkalinity of imidazole curing agents is relatively weak，Low volatility and no odor，Also more toxic than aliphatic、Aromatic amines are much smaller；Good thermal stability，Usually they hardly decompose below 250℃。
Imidazole and its modified epoxy curing agents are a very important anionic polymerization epoxy resin curing agent.，Less dosage，Long shelf life，Medium temperature solidification，Low volatility，Low or no toxicity，Excellent cured properties，Has outstanding bonding strength，Has excellent heat resistance、Mechanical properties and electrical insulation。Now there are many varieties such as 2MI、2NO、2E4MI、2PI and 2P4MI are both excellent curing agents，Also exhibits unique and excellent properties as a curing accelerator。
Imidazole and its derivatives are mainly used as curing agents for epoxy resins。With the development of industry，Demand is increasing year by year，Modified imidazole curing agent is also commonly used in adhesives、Sealants、coating、Potting sealing materials and composite materials。
