Abstract
A corrosion inhibiting composition includes one or more of a plurality of carriers, each having a carrier body and an organic corrosion inhibitor, such that the carrier body encapsulates the organic corrosion inhibitor, and the carrier body is formed of a degradable material. Coatings and methods for inhibiting corrosion on a metal substrate are also described herein.
