This article describes a simple and accurate method for measuring the reactivity and final cure state of epoxy resins. In the method, the reaction of a thin film of epoxy resin between two Nace plates is followed during a complete curing cycle. The method makes it possible to study effect of temperature and catalyst on cure rate, as well as comparing the equivalence of various materials. The techniques discussed in the article may be useful in the application of thermosetting resins other than epoxies.
