Fire Protection Effect Of Intumescent Steel Structure Fireproof Coating On Steel Barrier function. The high-expansion carbonized layer can effectively isolate the protected steel structure from air and heat sources, thereby effectively reducing the surface temperature of the steel structure and prolonging the support time of the steel structure in a fire. The heat absorption, softening, melting and expansion of the polymer coating, the physical change of the…

Bio based flame retardants In addition to inorganic fire retardants, certain plants have developed a defense mechanism against fire invasions due to their specific molecular structure. Bio based compounds in these plants owe their intrinsic fire retardancy to the formation of a thermally stable char layer when exposed to fire. A review of bio based flame retardants has been previously published by Costes …
