Evaluation of Flame-Sprayed Polymer Coatings for Civil Works Navigation Structures

Abstract

Provisions of the Clean Air Act Amendments of 1990 will further restrict the use of high solvent-content paints beginning in 1996, requiring the U.S. Army Corps of Engineers to replace some of the coatings now used to protect steel from corrosion in atmospheric and immersion exposures. To address this problem, the U.S. Army Construction Engineering Research Laboratories (USACERL) has experimented with several low-and zero-volatile emissions coating technologies. This report documents laboratory and field tests to evaluate the performance of flame-sprayed polymer coatings for potential use on Corps of Engineers navigation structures. Laboratory tests included salt and fresh water immersion, water resistance, atmospheric weathering, and ultraviolet (UV) condensation. Exposed test panels were evaluated for blistering, surface rust, adhesion, gloss retention, and rust undercutting. Plastic coatings were also evaluated for impact resistance. Standard Corps of Engineers coating formulations were used as experimental controls. Because of their relatively poor performance in these tests compared to the standard coating systems, flame- sprayed polymer coatings are not recommended at this time.
