Bio-based epoxy resin coatings for liquid ammonia carrier ballast tanks 2025-07-09 12:41:37 On July 7, 2025, China Coatings Corporation and Mitsui Chemicals Corporation announced that the bio-based epoxy resin coating CMP NOVA 2000 (Bio), developed by China Coatings Corporation, has obtained ISCC PLUS certification and has been selected by Keikyu Shipyard Corporation for use in the ballast tanks of liquid ammonia carriers under construction. This bio-based epoxy resin coating, CMP NOVA 2000 (Bio), uses bio-based epoxy resin raw materials produced by Mitsui Chemicals Corporation; this resin has obtained ISCC PLUS certification and is designed to reduce carbon dioxide emissions. Research by China Coatings Co., Ltd. indicates that this will be the world’s first commercial application of bio-based epoxy resin coatings in the shipbuilding industry. In addition, the bottom of this cargo ship will also be coated with the efficient anti-fouling paint SEA PREMIER 2000 PLUS, developed by China Coatings Co., Ltd.; this is expected to significantly reduce carbon emissions during the ship’s operation. The combined use of these two high-value-added coatings will enable carbon emission reduction throughout the entire life cycle of ships, from the production stage to their operational period. This liquid ammonia carrier is scheduled to be delivered in May 2026. CMP NOVA 2000 (Bio) is a bio-based epoxy resin coating for ballast tanks. It has obtained ISCC PLUS certification and is made from bio-based epoxy resins produced by Mitsui Chemicals using the mass balance method. While maintaining the same quality and coating performance as petroleum-based products, this new coating reduces carbon dioxide emissions by approximately 660 kg per ton of coating compared to the existing CMP NOVA 2000 (provisional figure). SEA PREMIER 2000 PLUS high-efficiency anti-fouling paint: As ammonia gains attention as a new generation of low-carbon energy source, shipbuilders are actively choosing high-performance, environmentally friendly products for new ships. Compared to traditional anti-fouling coatings, SEA PREMIER 2000 PLUS is expected to improve fuel efficiency by 5%-8%, thereby effectively reducing carbon emissions during ship operation.
