Abstract(s)
An investigation of two different intumescent coatings used in steel fire protection has been performed to evaluate their efficiency. A set of experimental
tests is presented. They were conducted in a cone calorimeter, considering different thicknesses and heat fluxes. Among other
quantities, the steel temperature and the intumescence thickness variation were measured. A numerical model for the paint decomposition is
also presented. Based on the intumescence experimental value, the model is able to provide a reasonably good prediction of the steel temperature
evolution.
