Abstract
A corrosion protective coating composition, applied over a metal surface, contains frangible microcapsules which rupture and release fluid upon impact or other stress likely to damage the coating. The fluid, from the microcapsules, contains a film forming component to cover the damaged area of the coating and a corrosion inhibitor for the metal surface.
