Accelerated aging at high temperature coupled with extrapolation is typically employed to predict the
service life of fusion bonded epoxy (FBE) coatings. This approach assumes that the aging mechanism
at high temperatures is the same as it is at the actual service temperature of the coating, which is
unlikely to be the case. Our proposed approach for determining the service life of FBE coatings is to
accelerate aging using increased oxygen concentration allowing data collection in a reasonable time at
different temperature set points. This could prove to be a more valid method to predict service life of
FBE coatings.
