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.

FBE Coating Process

The process of FBE coating comprises of essential components viz,


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 biphenyl A and epichlorohydrin. However, other types of resins (for example biphenyl (F type) is 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. With various types of curing agents used in FBEC process, the curing agent determines the nature of the final FBE product with 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, color, 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.


Its excellent adhesion to steel, provides a longer corrosion resistance and protection to Sub-Sea production structures (esp. Pipelines)

Its superior adhesion properties, provide excellent resistance to cathodic disbandment.

It complies to the highest industry standards of quality control.

It can be meet unique project specifications and performance requirements.

It can be applied as a dual layer coat, provides tough physical properties and minimizes the damage during handling and operation.

It has been designed for good chemical resistance under most soil conditions.


FBE coating is widely used for underground pipelines for coating of steel pipes, pipe fittings, pumps and valves used for the transmission of oil, gas, slurry, and water. It is also being used for the coating of steel reinforcement bars used in bridge, road, and building construction to help prevent corrosion when embedded in concrete.
