Dalian Kedun Anti-fouling Materials Co.,Ltd, located in Yingchengzi Subdistrict, Ganjingzi District, Dalian City, Liaoning Province, is a national high-tech enterprise specializing in research and development of metal corrosion protection technologies, manufacturing of anti-corrosion materials, and engineering applications. Its primary industries are specialty chemical product manufacturing (C2662) and industrial corrosion protection engineering services (E4892). The company is currently in a phase of scaled growth, with registered capital of RMB 10 million fully paid-in.  

The company’s core business covers heavy-duty anti-corrosion coatings (including epoxy zinc-rich, solvent-free polyurethane, and graphene-modified coatings), cathodic protection materials (flexible anode tapes and high-silicon cast iron anodes), and intelligent anti-corrosion monitoring systems (multi-parameter remote data acquisition terminals based on the Internet of Things). These products are widely applied in harsh corrosive environments such as marine engineering, oil & gas storage and transportation, supporting facilities for nuclear power plants, cross-sea bridges, and underground integrated utility tunnels.  

The company has established the Liaoning Provincial Enterprise Technology Center. Over the past three years, its R&D expenditure has averaged 7.3% of annual revenue. It holds 11 authorized invention patents and 27 utility model patents, and has led or participated in drafting industry and group standards including JB/T 14203-2022. Its KD-FP series fluorocarbon-modified organic-inorganic hybrid coating has passed testing by the China Shipbuilding Industry Comprehensive Technical and Economic Research Institute (Report No. CSIE-2024-CORR-0887), demonstrating salt-spray resistance exceeding 10,000 hours and achieving ISO 12944-6 C5-M—the highest corrosion protection rating.  

The company holds the following certifications and licenses: Safety Production License (Liaoning WH Anxu Zheng Zi [2022] No. 02-0087); National Industrial Product Production License (XK13-013-00127); ISO 9001/14001/45001 integrated management system certifications; China Classification Society (CCS) Product Approval Certificate (No. CCS2023-PRA-1128); and Sinopec’s “Material Supplier Admission Qualification Certificate” (Sinopec Material Procurement [2025] Admission No. 092).  

Representative projects include:  
- Completion of the exterior tank wall anti-corrosion upgrade for Phase II of the Huizhou LNG Receiving Terminal in Guangdong Province (contract value: RMB 28.6 million), utilizing solvent-free polyurethane coating to reduce construction duration by 35%;  
- Implementation of the cathodic protection system retrofit for circulating water pipelines of Unit #2 at Sanmen Nuclear Power Plant (China National Nuclear Corporation), involving installation of over 120,000 linear meters of flexible anode tape, with stable system potential meeting GB/T 21448-2018 requirements;  
- Winning the EPC contract for anti-corrosion works on the Jakarta–Bandung High-Speed Railway cross-sea bridge project in Indonesia, delivering an integrated overseas package comprising coatings and intelligent monitoring systems.  

Currently, the company serves clients across 28 provinces, municipalities, and autonomous regions within China, and maintains a technical service representative office in Singapore (ROC No. 202418765K). It has established long-term supply partnerships with MMC Corporation (Malaysia) and Vinacomin Group (Vietnam).
