A novel fusion bonded epoxy (FBE) coating based on brominated epoxy resin with a high glass transition temperature (Tg) was developed for pipeline protection. Properties of this FBE coating related to high temperature service are described in this paper. The new FBE coating has a glass transition temperature greater than 150°C as determined by differential scanning calorimetry (DSC). It performs significantly better in cathodic disbondment (CD) and water soak tests than conventional FBE coatings when tested at 95°C for 28 days. With brominated epoxy resin as the main binder, the new FBE coating has improved UV resistance. The new FBE should be used where superior cathodic disbondment performance at high temperature is needed.
