The Air Force Research Laboratory (AFRL) and its contractors, SAIC and Battelle, have completed a two-year effort to determine the durability and cleanability of new aircraft coatings submitted by coatings vendors. The Air Force prepared a detailed list of performance requirements that emphasize cleanability and weatherability, based upon user input. AFRL solicited coatings manufacturers, researchers, and formulators for innovative coatings that meet the prescribed requirements. These vendors submitted wet samples and coated aluminum panels for testing. The submitted samples underwent two phases of extensive testing: The first phase determined a coating baseline compared to a standard coating; the second phase allowed coatings vendors to reformulate based on first phase test results. The test protocol was selected to determine general performance properties such as water and solvent resistance, flexibility, adhesion, surface hardness, abrasion resistance, environmental exposure, and cure characteristics. In addition, the test regimen examined the effects on the performance properties of multiple stresses from temperature extremes, cyclic loads, rapid decompression, and UV exposures. This paper presents the results of the two phases of testing as well as conclusions regarding the most promising formulations for current aircraft painting needs.
