In this paper, we will investigate the influence of Al(OH)3 and nanoclay on the fire performance of epoxy-based intumescent retardant coatings. The fire protection properties of the intumescent retardant coatings were characterized by a scanning electric microscope (SEM), Energy dispersive X-ray spectroscopy (EDS), Fourier transformation infrared spectroscopy (FTIR), and Thermal gravimetric analysis (TGA). The results showed that, the sample added 5% Al(OH)3 decreased the plate’s backside temperature of 98-degree celsius compared to the control sample. Besides, char expansion and char residue of the sample added Al(OH)3 have values of 21 times and 17.42% respectively while these values of the control sample have 10 times and 12.61%. Therefore, Al(OH)3 is the most suitable candidate for improving the fire performance of the epoxy-based intumescent retardant coating for steel application in case of fire.
