The goal of this study was to find improved coating systems and techniques to facilitate corrosion control of topside systems for the U.S. Navy. Topside combat systems, especially antennas and other communication equipment, are exposed to the most severe marine environment. Topside systems are often exposed to high temperatures, intermittent seawater spray and exhaust gases, in addition to the marine atmosphere. Such equipment needs to be protected from these corrosive and destructive conditions. The Navy spends millions of dollars to impede or eliminate corrosion of its topside structures. The tiltable antenna experiences more severe conditions than most systems due to its location on the fantail of naval vessels. Because it is so close to the waterline, the tiltable antenna is exposed to constant seawater spray and intermittent seawater immersion with the movement of the vessel. In addition, the antenna is exposed to stack gases, high temperatures, oils, lubricants, and solvents. Occasionally, grit and dirt may fall on the antenna from sanding and grinding of adjacent equipment. As a result, tremendous man-hours and manpower are utilized to keep this system operational.

During the last two years, 18 coatings systems were tested to identify top performers which are environmentally compliant and provide corrosion protection as well as cosmetic appearance.

U.S. Navy tests found that PPG’s inorganic zinc primer with polysiloxa outperformed every other paint system in the world in reducing corrosion, while maintaining environmental compliance and cosmetic appearance. This product is currently in use for Naval topside systems and continues to perform every day. We’re proud to offer PPG paints and coatings at our various locations in Texas.
