| Abstract: | Abstract: The objective of this research was to demonstrate and implement cost-effective paint maintenance procedures for steel structures, including overcoating existing coatings with surface tolerant, self-healing, and extremely durable coatings. Maintenance painting of this type 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. Candidate steel and galvanized steel structures requiring maintenance painting at Fort Campbell were assessed to determine the suitability of various paint maintenance procedures, prior to overcoating. Air dry fluoropolymer coatings, implemented for the flight control tower, have emerged as a premium recoat product for factory installed polyvinylidene fluoride coatings as well as for use in coating other weathered coatings. Moisture cured polyurethanes (MCU), which are tolerant of relatively poor application conditions and generally can be applied at very high humidity and low temperatures, were successfully implemented as overcoatings for deluge tanks and aircraft hangars. Self-healing smart coatings, which incorporate microcapsules mixed into paint as a dry powder at the time of application, were also implemented for critical areas of deluge tanks. |
