Epoxy resins are widely utilized in a number of industrial applications. Imidazoles are often used as hardeners in a variety of epoxy resin systems in order to initiate the homopolymerization of the epoxy compounds. Unfortunately, imidazole is not a latent curing agent for epoxy resin systems. Imidazoles must be converted to an unreactable form in order to create a one pot system for the epoxy-imidazole system. In this study, imidazole curing agent was encapsulated with several polymers using the spray-drying method in order to create the one pot system for the epoxy-imidazole system. The effects of the ratio of imidazole and the polymer, and the effects of the molecular weight of polymer were investigated. The amount of imidazole in the microcapsule was measured using TGA. The permeability of the microcapsules was measured in ethanol, and the shelf life of the microcapsules was also studied for the epoxy resin. The curing behavior was examined using DSC. |
