What Is Fusion Bonding?
FBE coating is a thermosetting resin applied in the form of a dry powder onto the heated surface of steel pipe. The most frequently used powders are those based on epoxy resins, applied at thicknesses of 400-600 microns.
What Are Its Advantages?
The coating application system consists of numerous electrostatic spray guns that uniformly deposit the epoxy powder onto the blast cleaned, chemically treated and preheated surface of the pipe.
The correct surface temperature allows the fusion of the powder and assures the polymerization process, which is completed with a final cooling stage. Once applied and cured, the epoxy powder achieves an extremely hard surface with excellent adhesion to the steel surface.
Manufacturing Process
The process of applying fusion-bonded epoxy coating to steel reinforcement involves four major steps: surface preparation, heating, powder application and curing.
Epoxy coatings are environmentally friendly materials. Unlike many paints, the fusion-bonded epoxy coatings used for steel reinforcement do not contain appreciable solvents or other environmentally hazardous substances. Systems used to apply the coating are very efficient, resulting in little material loss to the atmosphere and little waste disposal.
3M Scotchkote™ 134
3M Scotchkote™ 134 Fusion Bonded Epoxy Coating is a one-part, heat curable, thermosetting epoxy coating designed for corrosion protection of metal. The epoxy is applied to preheated steel as a dry powder which melts and cures to a uniform coating thickness.
This bonding process provides excellent adhesion and coverage on applications such as valves, pumps, pipe drains, hydrants and porous castings. 3M Scotchkote™ 134 coating is resistant to wastewater, corrosive soils, hydrocarbons, harsh chemicals, and sea water. Powder properties allow easy manual or automatic application by electrostatic or air-spray equipment.
3M™ Scotchkote™ 206N
3M™ Scotchkote™ 206N, has been a pipe coating standard since 1974. It is available in a wide variety of gel/cure time ranges for automatic or manual application to external and internal surfaces of pipe, associated appurtenances and field joints. The coating exceeds all industry pipe-coating standards and meets NSF 61 for drinking water.
