The coating presented in this research article was based on expandable graphite, ammonium polyphosphate, melamine, and boric acid. Bisphenol A epoxy resin BE-188 was used as a binder with ACR hardener H-2310 polyamide amine. Different formulations were developed to study the effect of expansion and heat shielding after fire testing. The coating was tested at 950°C for 1 h. The results show that the coating was stable and well bonded with the substrate. The coating was characterized with thermogravimetric analysis (TGA, Parkin Elmer, Norwalk, CT, 06859, USA), Fourier transform infrared (FTIR, Nicolet 400 D Shimadzu spectrometer) spectroscopy, X-ray diffraction (XRD, Bruker D8 advance Diffracto meter, Bruker Germany), and scanning electron microscopy (SEM, Carl Zeiss Leo 1430VP, UK). The morphology of char was studied by SEM on the coating after fire testing. XRD and FTIR spectroscopy showed the presence of graphite, boron phosphate, boron oxide, and sassolite in the residual char. TGA (Pyris 1, manufactured by Parkin Elmer, Norwalk, CT, 06859, USA) and differential thermal gravimetric analysis (DTGA) showed that boric acid enhanced the residual weight of the intumescent fire-retardant coating. © 2012 Wiley Periodicals, Inc. date: 2013 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84874935597&doi=10.1002%2fapp.38318&partnerID=40&md5=0fc7200f6edbb421a75f58c4c5a625a2 id_number: 10.1002/app.38318 full_text_status: none publication: Journal of Applied Polymer Science volume: 128 number: 5 pagerange: 2983-2993 refereed: TRUE issn: 00218995 citation: Ullah, S. and Ahmad, F. and Yusoff, P.S.M.M.
