Patent AT-E400620-T1: [Translated] ANTIFOULING PAINT FOR SHIP HULLS AND METHOD FOR APPLYING SAME

Published by National Center for Biotechnology Information (NCBI) | U.S. Department of Health & Human Services | Metadata Last Checked: September 07, 2025 | Last Modified: 2025-09-06
A marine anti-bio-fouling coating 10, for application onto the surface of a marine article 12. The coating 10 comprises a self-levelling, self-curing epoxy resin primer adhesive 14, an adhesive modified epoxy resin binder adhesive 16 and granulated Copper Nickel alloy 18. When a coated marine article 12 is immersed in water a chemical reaction occurs between the water and the Copper Nickel alloy 18 which causes a film of a complex metal oxide 20 to form on the exterior surface of the layer of Copper Nickel alloy granules 18. The oxide film 20 forms an inhospitable environment to aquatic organisms and aquatic borers, thereby preventing bio-fouling occurring on the coated marine article. A method of applying the coating 10 to a marine article 12 is also provided.
