Fusion bonded epoxy powder coating which is commonly referred to as FBE coating, is an epoxy-based powder coating that is widely used to protect steel pipe used in pipeline construction, concrete reinforcing bars and on a wide variety of piping connections, valves etc from corrosion. FBE coatings are thermoset polymer coatings. The coating application temperatures, usually in the range of 180 to 250 C (356 to 482 F), the contents of the powder melt and transform to a liquid form. The liquid FBE film wets and flows onto the steel surface on which it is applied, and soon becomes a solid coating by chemical cross-linking, assisted by heat. The chemical cross-linking reaction taking place in this case is irreversible. Once the curing takes place, the coating cannot be returned to its original form by any means.


The process of FBE coating comprises of essential components viz,

  • Resin
  • Hardener or curing agent
  • Fillers and extenders
  • Colour pigments

The resin and hardener part together is known as the "Binder". As the name indicates, in Fusion bonded epoxy coatings the resin part is an "epoxy" type resin. The most commonly used FBE resins are derivatives of bisphenol A and epichlorohydrin. However, other types of resins (for example bisphenol F type) are also commonly used in FBE formulations to achieve various properties, combinations or additions. Resins are also available in various molecular lengths, to provide unique properties to the final coating.

The other part of FBE coatings is the curing agent or hardener. Curing agents react either with the epoxy ring or with the hydroxyl groups, along the epoxy molecular chain. Various types of curing agents, used in FBE manufacture, include dicyandiamide, aromatic amines, aliphatic diamines, etc. The selected curing agent determines the nature of the final FBE product its cross linking density, chemical resistance, brittleness, flexibility etc. The ratio of epoxy resins and curing agents in a formulation is determined by their relative equivalent weights. Apart the above two major components, FBE coatings include fillers, pigments, extenders and various additives, to provide desired properties. These components control characteristics such as permeability, hardness, colour, thickness, gouge resistance etc. All of these components are normally dry solids, even though small quantities of liquid additives may be used in some FBE formulations. If used, these liquid components are sprayed into the formulation mix during pre-blending in the manufacturing process.

  • Oil & Gas Pipeline
  • Large & Small Diameter Pipeline
  • Waterworks pipeline
  • FBEs excellent adhesion to steel provides superior long term corrosion resistance and protection to pipelines and other subsea production structures
  • Superior adhesion properties provide excellent resistance to cathodic disbandment which reduces the total cost of cathodic protection during the operation of the pipeline.
  • Our FBE custom coatings are applied in fixed facilities that comply to the highest industry standards of quality control
  • It can be applied in a wide range of thicknesses to cost effectively meet unique project specifications and performance requirements
  • Good flexibility of the FBE custom coating systems over a wide temperature range accommodates the strains seen during installation
  • FBE can be applied as a dual layer product which provides tough physical properties that minimize damage during handling, transportation, installation and operation.
  • FBE has been designed for good chemical resistance under most soil conditions.
  • The same grade of FBE powder can be applied on the line pipe, field joints, and other custom fabricated subsea production structures, providing continuous corrosion protection along the entire length of the pipeline
