fire propagation performance of intumescent fire protective

Intumescent fire retardant coating (IFRC) is applied on the surface of material requiring fire protection. In this research work, IFRC’s were developed using ammonium polyphosphate, expandable graphite, melamine, boric acid, zinc borate, mica, magnesium oxide, and bisphenol A BE-188 with polyamide polyamine H-4014 as curing agent.


Intumescent paints are specially formulated reactive coatings designed to swell or expand into thick foamed char upon exposure to heat, protecting the substrates against fire by insulation and providing a protective barrier to heat and mass transfer.

2016-10-24 · BS 476 Hydrocarbon Fire/NPD Heating Regime Intumescent coatings have been used to protect the steelwork in buildings and other structures from fire for approximately 40 years. These coatings work by swelling up in the event of fire and physically creating a barrier between the steel and the fire for up three hours.


2021-1-28 · The aim of this study was to evaluate the performance of intumescent coatings based on chemically modified tannin in passive fire protection. For this purpose, chemical modification of tannins was carried out with phosphorus pentoxide or phytic acid. Following this, a set of paints were formulated, each of which contained one of the tannins in combination with expandable graphite and ammonium ...

Intumescent fire-resistive coatings accomplish this by forming an intumescent char layer that insulates the structural steel from the heat of the fire. The author describes the roles of the resin components of the coating and considers how performance is evaluated.


The fire protection provided by intumescent coatings occurs by three reaction processes: (i) the coating material decomposes, (ii) inert gases evolved from the decomposition reaction are produced at a rate high enough to drive back hot convective air currents, and (iii) the coating expands into a highly porous char layer with a high resistance to heat conduction from the flame into the underlying steel substrate …


The failure time of polyvinylchloride (PVC) insulated power cables was studied using an infrared radiation heating furnace and insulation resistance measurements. The temperature-time curve inside the furnace was similar to that of the ISO 834 standard. Two popular fire protection methods were employed for the cables; one method applied fire-retardant coatings directly on the cable surface ...
