The Science of Superiority – Unpacking Fusion Bonded Epoxy (FBE) Technology
At the core of Center Enamel’s high-performance FBE tanks lies the sophisticated application of Fusion Bonded Epoxy (FBE) technology. Unlike traditional liquid paint applications, FBE is a thermosetting epoxy polymer coating applied as a dry powder. The process begins with meticulous preparation of the steel panels, ensuring a perfectly clean and profiled surface – typically achieved through abrasive blasting to a near-white metal finish. This crucial step enhances the mechanical adhesion of the subsequent coating.
Once prepared, the preheated steel panels are introduced into a specialized chamber where the finely ground epoxy powder, electrically charged, is electrostatically sprayed onto their surfaces. The heat of the steel causes the powder to melt, flow, and chemically fuse, or "bond," to the substrate. This fusion bonding creates a continuous, uniform, and incredibly adherent film that becomes an integral part of the steel itself. As the panels cool, the epoxy cures, forming a tough, impenetrable barrier that is exceptionally resistant to corrosion, abrasion, and chemical degradation. This chemical bond is a critical differentiator, providing superior adhesion and long-term protection compared to mere physical adhesion offered by many conventional liquid coatings.
The integrity and performance of our FBE tanks are further elevated by our exclusive partnership with AkzoNobel, a global leader in coating technology. We utilize their industry-leading products: Resicoat® R4-ES for internal tank surfaces and INTERPON D2015 for external surfaces, each specifically chosen and tested for optimal performance in their respective roles.
