Janssen Preservation and Material Protection announced that an Econea-containing antifoulant coating is being used by the U.S. Navy and the U.S. Coast Guard to protect military seacraft. Developed by Janssen PMP, Econea is a metal-free antifouling agent that protects vessels against aquatic growth without a potential negative impact on the marine environment compared to traditional, copper-based antifoulants. The coating was recently used to coat the 560-ft nuclear submarine USS Nevada. It is also being applied to U.S. Coast Guard aluminum hull crafts, eliminating the risk of galvanic corrosion that can occur when copper-based paints are applied to aluminum.
