Epoxy Coated Rebar acts as a barrier system intended to prevent moisture and chlorides from eroding the surface of the reinforcing bar. It rebars corrosion performance. Epoxy Coated Rebar is used to provide additional protection in environments where reinforcements are subjected to accelerated corrosion. The use of these bars is significantly increasing as the concrete use is becoming more diverse in corrosion-prone areas.
These types of bars are coated with Fusion Bond. These coatings are in the form of dry powder at normal atmospheric temperature. The powder is applied electrostatically to the surface of cleaned hot steel bars and cured to form a protective film after undergoing various chemical processes. The epoxy-coated rebars last longer due to the protective film and thereby contribute to the quality of construction. A good quality Epoxy Coated TMT Bar must have a uniform coating, Chemically stable and adhere to a high pH environment.
