Advanced 2K and 1K Topside Coatings for the U.S. Navy

The Naval Research Laboratory has recently developed advanced two-component (2K) and single-component (1K) coatings to replace the traditional and often problematic silicone alkyd topside coatings on U.S. Navy ships.  The two-component systems are based on a unique formulation of commercially available siloxane-based materials that together provide color stable and gloss retentive coatings with superior performance to silicone alkyds.  The single-component systems are based on a novel and proprietary resin that provides even greater exterior durability than the aforementioned two-component siloxanes, while also engendering formulations that is low in VOCs, non-toxic, curable over a wide range of conditions, and designed for use by ship’s force. Both systems can be applied over primed or bare steel surfaces in a conventional manner (spray, brush or roll).
