What is the difference between epoxy and FBE?
Epoxy resin and FBE (fusion bonded epoxy powder coating) are two different materials that are mainly used in the field of coatings and anti-corrosion. The following are the main differences between them:
Composition and structure:
Epoxy resin: Epoxy resin is a high molecular polymer formed by the polycondensation of epoxy resin chloropropane and bisphenol A or polyol, and has more than two epoxy groups. These epoxy groups are highly chemically reactive and can form a cross-linked network structure by reacting with compounds containing active hydrogen, thereby providing excellent mechanical properties and chemical stability.
FBE: FBE is the abbreviation of fusion bonded epoxy powder coating. It is an anti-corrosion coating applied by fusion bonding and is usually used on the inner and outer walls of steel pipes. FBE coating is mainly composed of epoxy resin, curing agent, pigment and filler. It is applied to the surface after heating and melting, and quickly solidifies to form a strong coating.
Construction method:
Epoxy resin: It is usually used to make coatings, adhesives, etc., and can be applied by brushing, spraying or dipping.
FBE: FBE is a powder coating constructed by a sintering process. During construction, the powder is melted by heating and then quickly applied to the metal surface to form a solid coating.
Features and applications:
Epoxy resin: It has good adhesion, chemical resistance and mechanical strength, and is widely used in coatings, packaging of electronic devices, etc.
FBE: It is mainly used for anti-corrosion coating of steel pipes, especially buried pipes. FBE coating has excellent corrosion resistance and wear resistance, and the construction is relatively simple and can be carried out on site.
