Engineered for Safety, Reliability, and Performance
Anti-Friction Coatings for Lifetime, Maintenance-Free Lubrication
DOAH Co., Ltd., a company specializing in Anti-Friction Coatings (AFC), provides customized solutions for customers through close collaboration at every stage — from product design and tailored formulation to performance validation. This ensures long-term lubrication performance and consistent quality of components.
We continuously develop coating products that enable friction control, wear prevention, and corrosion inhibition, ensuring reliable operation even in extreme environments. To keep pace with rapidly changing market demands and technological advancements, we invest consistently in product innovation. Through these efforts, we transform our customers’ complex requirements into high-performance, cost-effective solutions, ultimately enhancing component durability and system reliability.
In the field of Anti-Friction Coatings (AFC), DOAH Co., Ltd. is more than just a manufacturer supplying products — we are a strategic partner who works hand-in-hand with our customers to solve their technical challenges.
We conduct a thorough analysis of the unique friction conditions, load characteristics, and environmental constraints of each industry and component, then design tailor-made formulations based on these insights. Rather than simply recommending a product, we quantify performance, validate results with data, and help our customers secure predictable quality and reliability.
Our capabilities include ensuring coating compatibility across a wide range of materials (metals, plastics, elastomers), evaluating stability under extreme conditions such as low/high temperatures, vacuum, and corrosive environments, and systematically managing key tribological indicators such as friction coefficient, stick-slip behavior, and wear resistance.
Thanks to this technical depth, our customers gain more than just a coating solution — they achieve extended component life, optimized maintenance intervals, and enhanced system reliability.
In addition, we proactively respond to global regulatory changes and emerging industry trends, investing in forward-looking innovations such as eco-friendly processes and advanced functional additives. As a result, our customers are equipped with sustainable solutions that meet evolving market demands and strengthen their competitive edge.
