Intumescent fire retardant coatings are the most common type of fire retardant coatings for steel. When exposed to high temperatures or flames, these coatings expand rapidly to form a thick, foam-like, thermally insulating protective layer. This protective layer not only effectively blocks the conduction of heat, but also prevents the flame from directly contacting the steel, thereby maintaining the structural strength of the steel for a period of time.
