FUSION BONDED EPOXY COATING ON REBARS


(MYSTERY AND CHEMISTRY)

Mysteries behind the conventional problem:



The most basic and inexpensive form of rebar consists of steel bars. While effective at boosting internal strength, steel rebar often falls prey to corrosive forces as times goes on. As rust forms on outside of the embedded rebar, it creates an increasing amount of pressure on the surrounding concrete.

Such internal pressure can cause the concrete slab to spontaneously crack, while also making the concrete must more vulnerable to damage caused by blows and compressive forces. The surface of the concrete may develop rough patches, unattractive areas as the concrete chips and flakes away.

Steel rebars are prone to corrosion due to chloride permeability.


Chemistry with its innovative solution:

Reinforcement bars are essential materials in concrete structures, providing tensile strength and structural support. Epoxy coating serves as a safeguard, reducing the risk of corrosion and increasing the lifespan of reinforced concrete structures. By enhancing durability and diminishing maintenance needs. FBE coating hinders chloride permeability thus increases the corrosion resistance.

The epoxy is applied to shotblasted preheated steel bars as a dry powder which melts and cures to a uniform coating thickness. This bonding process provides excellent adhesion and coverage on concrete reinforcing steel bar and other steel members of any size or shape. This coating is resistant to corrosive agents such as de-icing salts, airborne salt spray, sea water, harsh chemicals, acid rain, carbonation, contaminated aggregate and concrete additives.
