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.
L'invention concerne une composition de revêtement anticorrosion destinée à être appliquée sur une surface métallique, qui contient des microcapsules cassables qui se rompent et libèrent un fluide lors d'un choc ou d'une autre contrainte susceptible d'endommager le revêtement. Le fluide provenant des microcapsules contient un constituant formateur de film qui sert à couvrir la zone endommagée du revêtement, ainsi qu'un inhibiteur de corrosion utile pour la surface métallique.
