|Abstract:||Abstract: This project demonstrated the following cost-effective paint maintenance procedures: utilization of smart coatings containing fluorescing compounds, self-healing microcapsules, and purpose-formulated surface tolerant coatings to overcoat existing paints. Smart coatings incorporate microcapsules, and fluorescing compounds which are mixed into paint at the time of application. Microcapsules instill the coating with self-healing, corrosion resistance, and passive sensing capabilities. Fluorescing compounds improve the coating service life by faster and better inspections, early identification of problems, and timely repairs. The overcoating process does not require extensive surface preparation, and can be significantly less expensive than other maintenance practices, particularly when the existing coating contains lead or other hazardous materials. The smart coatings were demonstrated on pipes used in a water-handling system for a central vehicle wash facility. The overcoating procedure was demonstrated on two types of structures: steel tanks and corrugated steel hangars. It is recommended that these technologies be implemented as standard practice for coating of steel structures for the Army and DoD.|
