ABSTRACT:
A composition is provided which, when applied to a metal surface, forms a corrosion-inhibiting film thereon. The composition comprises an epoxy resin, an effective amount of a curing agent for the epoxy resin, an onium salt, and a hydrocarbon diluent. The composition optionally further contains an alcohol. The onium salt can be, for example, a quaternary ammonium salt. The composition is applied by contacting the metal surface with the composition. The composition is useful in the treatment of downhole metal surfaces in oil and gas wells to inhibit corrosion of the metal.
