Abstract: Intumescent epoxy resins are used commercially for fireproofing because of their ability to swell. The swelling action is initiated to shelter the materials beneath the resin from any potential heat source. In this study, the thermal degradation of the intumescent epoxy resins was researched, paying close attention to the morphology of the material and the overall swelling mechanism occurring. It was determined that the thermal degradation process inherently alters the thermal conductivity, density and volume of swelling of the material at hand. A model was developed to describe these alterations as a function of material conversion and temperature. To allow for precise and accurate investigations into the fireproofing capabilities of the intumescent epoxy resins, the model allows users to simulate thermal degradation at any desired temperature.
