Paint markings on runways and taxiways are damaged from ultraviolet rays, stained by aircraft fuel, and discolored. Glass coatings, used as a sealant for the paint, have shown promise as a possible solution to these problems. The research effort described in this report investigates the effectiveness of an Anchored Dendritic Silicate Interactive Linkages (Adsil) Ambient Temperature Cure glass coating material in protecting the color and retro-reflectivity of the paint markings. The paint markings in this study included two types of beads for better visual acquisition. Testing was conducted at the Jacksonville Naval Air Station and Whitehouse Outlying Landing Field. The tests measured resistance to abrasion, mildew, rust staining, oil staining, and ultraviolet weathering. The results of the tests showed Adsil glass coating reduced retro-reflectivity. |
