Curing kinetic model of the 2-ethyl-4-methylimidazole/epoxy system
The system of bisphenol-A diglycidyl ether type epoxy resin (DGEBA) cured with 2-ethyl-4-methylimidazole (2,4-EMI) was studied by means of differential scanning calorimetry (DSC) in isothermal mode.
US5508328A - Curing epoxy resins using dicy, imidazole and acid
A curable epoxide composition consists essentially of curable epoxides, dicyandiamide as a curing agent in an amount less than needed to fully cure the epoxides, an imidazole in an amount exceeding that needed as a catalyst and capable of curing the epoxides in combination with the dicyandiamide, a reactivity controller for the imidazole to reduce the curing speed, and a solvent.

Curing Agent - an overview | ScienceDirect Topics
A combination of amine with acid such as ethylenediamine/phthalic acid, 1,3-propanediamine/phthalic acid, ethylene-diamine/adipic acid, 1,3-propane diamine/adipic acid and p-phenylene diamine/adipic acid are also employed as curing agents for vegetable oil-based epoxy resins. 18 Epoxy resin can also be cured by polyimide, polyamic acid and
Acceleration of Epoxy Resin Systems
hydrolyzed DGEBA resins became the “standard bisphenol A epoxy” or “liquid epoxy resin (L.E.R.)” type resin, as it met the requirements of the broadest assortment of end-users. Although these higher viscosity hydrolyzed resins are needed for some applications, other applications, such as the molding of large composites, greatly

and the all are important curing agents for epoxy resin. Aliphatic amine (Three Bond 2103) is curing agent for epoxy resin ant able to cure at room temperature. The cured resin has excellent properties, and its heat resistance is 100°C. Aromatic amine has been developed to achieve greater heat resistance and chemical resistance than
CA1175996A - Co-curing agents for epoxy resins - Google Patents
ABSTRACT OF THE DISCLOSURE A N-substituted piperazine or N-substituted homopiperazine adduct with a polyepoxide is used as a co-curing agent such as dicyandiamide. a carboxylic acid anhydride, or a dihydrazide. The preferred adducts have a ratio of epoxy groups to secondary amino groups of between 1.2:1 and 3:1.
