Abstract
Embodiments provide a self-healing coating formulation comprised of a one component waterborne epoxy-amine adduct resin system and a microencapsulated healing agent. The self-healing coating formulation hardens to a protective material upon application to a substrate. Components in the protective material and microencapsulated healing agent are uniquely synergistic with each other such that, upon degradation of the protective material, microcapsule rupture causes release of the healing agent, whereby components of the healing agent react with components of the protective material to increase adhesion maintenance and corrosion resistance of the protective coating.
