Effect of encapsulated curing agent on viscosity of the liquid epoxy system

Encapsulation of the curing agent is a promising and economic method for forming non-reactive curing agent. In this study, the viscosity of microcapsules embedded epoxy resin was determined by Brookfield viscometer. The results revealed that although the viscosity of microcapsule/epoxy systems increased by increasing microcapsule content, the viscosity of epoxy system becomes very more by increasing of the residence time of microcapsule in epoxy resin. Fourier transform infrared spectroscopy showed that all the epoxy functional groups of the microcapsule’s shell do not participate in the curing reaction with the core curing agent
