A Study of Formulations and Thermophysics of Intumescent Systems

Abstract

A variety of intumescent systems were formulated. After screening, six formulations were evaluated further by application of the coatings to metal substrates and exposure to a heat source typical of an aviation fuel fire. The thermal responses are compared to a baseline formulation. Additionally, the self-limiting affect of pressure on intumescence was inferred from differential scanning calorimetry; and models were developed for estimating the effective thermal conductivity of the char from either the temperature-time response of coated coupons, or from theoretical considerations. Keywords: Intumescence; Thermal protection; Insulation; Intumescent systems; Intumescent paint; Thermal conductivity; Char; Cookoff; Weaponscook off improvement.
