Intumescent coating is used in buildings as a passive fire resistance measure. Most commonly, the coatings are thin films used as fireproofing materials for steel structures that support a building. The main feature of intumescent coating is that it expands and carbonizes when exposed to fire. This expansion provides an insulating layer that delays the effects of heat on the structure during a fire event.
