Thermal Degradation of Painted Wood. an Experimental Study

A comparative study of thermal degradation of painted and unpainted parti cle board specimens has been carried out. Experiments based mainly on the measurements of piloted ignition delay, mass loss rate and temperature profile have been performed using a radiative heat flux equal to 2.4 W/cm ² . Thermo gravimetric analysis has complemented these measurements. It has been shown that thermal degradation of paints produces a solid residue which strongly affects exchange phenomena at the wood surface and consequently the thermal behavior of wood.
