FBEs are available as stand-alone coatings as well as a part in multi-layers. Today, various types of FBE coatings, which are tailor-made to meet various requirements are available. Since their introduction as a protective coating in early 1960s, FBE coating formulations had gone through vast improvements and developments. Application of further heating will not “melt” the coating and thus it is known as a “ thermoset” coating. ![]() Once the curing takes place, the coating cannot be returned to its original form by any means. The chemical cross-linking reaction taking place in this case is irreversible. This process is known as “fusion bonding”. 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. At typical coating application temperatures, usually in the range of 180 to 250 ☌ (356 to 482 ☏), the contents of the powder melt and transform to a liquid form. The resin and hardener components in the dry powder FBE stock remain unreacted at normal storage conditions. ![]() In 2020 the market size was quoted at 12 billion dollars. The name fusion-bond epoxy is due to resigning cross-link and the application method, which is different from a conventional paint. They come under the category of protective coatings in paints and coating nomenclature. FBE coatings are thermoset polymer coatings. It is also commonly used to protect reinforcing bars (though being phased out as of 2005 ) and on a wide variety of piping connections, valves etc. JSTOR ( January 2021) ( Learn how and when to remove this template message)įusion bonded epoxy coating, also known as fusion-bond epoxy powder coating and commonly referred to as FBE coating, is an epoxy-based powder coating that is widely used to protect steel pipe used in pipeline construction from corrosion.Unsourced material may be challenged and removed.įind sources: "Fusion bonded epoxy coating" – news ![]() Please help improve this article by adding citations to reliable sources.
