%X Intumescent coating is a method of passive fireproofing that is applied to structural members of building and helps prevent the fire heat from reaching the structure. The issue with fibre reinforced intumescent coating was that the fibre tend to coagulate when the coating was applied to the structure because they did not have a good dispersion. In the current study, a coating was prepared with basic components of ammonium polyphosphate (APP), expandable graphite, and melamine (MEL) in an epoxy resin base with boric acid as additive. Basalt fibres were used as reinforcements with BYK-9920 as the dispersing agent and their effects on thermal properties were investigated. The coating was applied by brushing onto steel substrates of 100 cm2 and 25 cm2 area. The effects of different weight percentage of the reinforcements were studied by performing fire test and furnace test for heat shielding effect and char expansion. Further analysis was performed by thermogravimetric analysis (TGA) for residual weight and thermal stability. From the TGA, the formulations showed increase in final residual weight. The coatings were able to expand up to 635 and reduce the substrate temperature from 1000°C to 180°C. © 2018 Author(s).
