ABSTRACT
The aim of this study is to investigate the influence of fibreglass addition into the
basic intumescent coating formulation towards the enhancement of its thermal
insulation properties. The intumescent coating were formulated from expandable
graphite (EG), ammonium polyphosphate (APP), melamine (MEL), boric acid (BA),
bisphenol A epoxy resin BE-188 (BPA), ACR Hardener H-2310 polyamide amine
and fiberglass (FG) of length 3.0mm. Eight different intumescent formulations were
developed and the samples were tested for their fire performance by burning them at
450 ºC, 650 ºC and 850 ºC in the furnace for two hours. The effects of each fire test
at different temperatures; low and high temperature were evaluated. Scanning
Electron Microscope (SEM), X-Ray Diffraction technique (XRD) and
Thermogravimetric Analysis (TGA) were conducted on the samples to study the char
morphology, the crystalline material structure and chemical components and the
thermal analysis of the coatings. The FG08 and FG07 formulations with 7.0 grams
and 6.0 grams fiberglass provide better results with the enhanced thermal insulation
properties of the coatings.
