%X Intumescent fire retarding coatings are designed to insulate the substrate under the action of fire. In this research to study the effect of Aluminium Trihydrate (ATH) and Fumed Silica (FS) on Expandable Graphite (EG) Intumescent Fire Retardant Coating (IFRC). The IFRC was based on EG, Ammonium Poly Phosphate (APP) as a acid source, melamine (MEL) as a blowing agent, Boric Acid (BA) as additive, ATH, FS as inorganic fillers and bisphenol. A epoxy resin BE-188 (BPA) was used as a binder with Hardener H-2310 polyamide amine. A range of different formulations were developed to study the char expansion, morphology of char and thermal properties of the IFRC. The formation of the final charring layer and their morphological structures was studied by Scanning Electron Microscopy (SEM). Char composition was determined by X-Ray Diffraction (XRD) technique. Thermogravimetric Analysis (TGA) was used to study the thermal stability of coating. Shear test was used to determine the bonding strength. IFRC with ATH give a better performance than fumed silica with 4 wt. of ATH gives the best performance than others formulation in term of char expansion heat shielding, char residual weight and boding strength. © 2012 Asian Network for Scientific Information.
