Abstract
The effectiveness of innovative polymeric coatings, polyurea and Poly aspartic polyurea, to protect structural steel from corrosion was investigated through standard laboratory tests. the coating evaluation tests included salt fog test, QUV weathering test, adhesion test, and freeze-thaw stability test. These tests were used to assess the long-term performance of coating technologies compared to the conventional polyurethane type coatings, i.e. coating systems with inorganic zinc primer, epoxy intermediate coat and polyurethane topcoat. This paper presents part of results in the aforementioned evaluation tests. the results illustrate that Poly aspartic coating systems are very promising for corrosion mitigation and can provide long-term adhesion strength for transportation steel structures. in addition, compared with the coating systems currently used by Department of Transportation's (DOT's), the polyaspatic coating systems performed equally well with even higher bond strength. © 2011 ASCE.
