An extensive experimental program has been conducted on intumescent systems where the components have been systematically varied. Small plates were coated with the various formulations, exposed to a heat source typical of aviation fuel fires, and the temperature-time history of the substrate recorded. Concurrently, a simplified mathematical model was developed for an intumenscing system which has given insight to the fundamental mechanisms of intumescence. The model and the results of the experimental program demonstrated certain desirable features of intumescent systems and hold the promise of guiding the optimization of certain promising formulations to thermally protect Navy ordnance.
