One-Coat Systems Applicable to Steel Bridges

The Coatings and Corrosion Laboratory at Turner-Fairbank Highway Research Center of Federal Highway Administration has been evaluating eight one-coat systems plus two control systems; a 3-coat and a 2-coat. Test materials were applied over near-white steel test panels (SSPC-SP10). This study was launched in November 2006, as part of a congressionally mandated high performance steel research program, and will be completed in December 2008. A total of 168 test panels were prepared and tested through accelerated laboratory testing and outdoor weathering testing at two exposure sites. Performance of the coating systems has been evaluated using Electrochemical Impedance Spectrosocpy (EIS), surface failure characterizations, rust creepage at intentional scribes, pull-off adhesion, and changes of color and gloss.
