Not Available Painted coatings are not perfect and their integrity is constantly challenged. During everyday use, scratches or scribes are often introduced into a coating. Where this occurs, the underlying metal is exposed directly to the environment and this favors accelerated corrosion. Thus, there is a need for so-called smart coatings that can spontaneously heal themselves wherever they are damaged. Incorporation of microcapsules loaded with a multifunctional corrosion inhibitor into a coating formulation offers this possibility. Wherever such a coating is scratched or scribed, the microcapsules are designed to rupture and release their corrosion inhibitor contents to cover the damaged area thereby providing corrosion protection to this area. The overall goal of the proposed program is to develop an effective corrosion inhibiting coating system for outdoor use on steel enclosed appliances and equipment. The coating system will be based upon a primer that contains a microencapsulated corrosion- inhibiting liquid formulation. Variables associated with microcapsule parameters and coating parameters will be investigated. Salt spray and electrochemical characterization of coatings will be conducted to assess the efficacy of the self-healing coatings. BENEFITS: The US Army estimates that the cost for painting/depainting operations is $2 billion per year. In addition, Navy and Air Force coating requirements for steel and aluminum are significant dollar volume. In the consumer area, a
