Review of heat exposure equipment and in-situ characterisation techniques for intumescent coatings

The performance of commercial intumescent coatings is assessed by industrial norms and standards with clearly defined experimental conditions. In contrast, academic research on much more diverse there are no clear guidelines how such should be characterised. Some researchers transfer the conditions in to laboratory-scale setups while others rely cone calorimeters or Bunsen burners. This might not an issue when comparing different coating formulations within one study. However, it significantly complicates comparison characterised approaches usually provides little insight into under fire test review article gives overview over reported literature for evaluation coatings. heating these groups setups, ranging from furnaces ovens radiative heaters impinging flames, elaborated a tutorial style fashion. Besides sample heating, in-situ characterisation techniques, as measurements char expansion, temperature, mechanical strength will discussed. aim aid evaluating reports well stimulate development new optimisation existing approaches.
