Scholarcy highlights

  • Properties and microstructure of particulate-filled epoxy-based coating under UV exposure
  • To minimise the UV degradation, epoxy polymers are being applied as protective coatings to composite materials to retain properties during their design service life
  • The polymer coating contains up to 60% by volume of hydrated alumina powder fire retardant and fillers such as an industrial waste like fly ash and is exposed to simulated UV conditions either 1000 h or 2000 h
  • No reduction in the flexural strength was observed for polymer coating containing at least 40% fillers, indicating that the FR and FA retained the structural performance of the coating
  • From the results of this study, a coating thickness of at least 11 mm is required for epoxy based polymer coating with 60% by volume fillers, which is 5 times thinner than neat epoxy resin, to provide 100 years of UV resistance
