Abstract

The aim of this work is to investigate various factors influencing the performance of intumescent coatings (IC) at elevated temperatures. During this study, several experimental investigations are conducted using gas furnace and cone calorimeter. These tests are performed on steel plates protected with three different intumescent coatings having varying dry film thicknesses and exposed to several fire scenarios and heat fluxes. Investigations have also been conducted to cover the various ranges of section factors of the steel plates. A comparative study on the furnace and the cone results was also conducted. The results from cone and furnace tests show that the nature of test produces different IC char structures at the end of the heat exposures. The expansion of the IC and the thermal conductivity appears to depend on the experimental set-up and the fire exposure scenarios. Nevertheless, the activation temperature of IC was found to be same in all the cases.
