Major Release! The Technical Specification for Wear-Resistant Superhydrophobic Coatings for Wind Power Systems Supports High-Quality Development of the Wind Power Industry.

Aug 05,2025

With the rapid growth in global demand for clean energy, wind power—作为一种 crucial form of renewable energy—is experiencing unprecedented development opportunities. However, wind power systems, which are exposed long-term to complex and ever-changing natural environments, face multiple challenges including windblown sand erosion, rain, snow, and freezing conditions, as well as ultraviolet aging. These factors place higher demands on the durability and operational efficiency of the equipment.
To address these challenges, the China Inspection and Testing Society has officially released the "Technical Specification for Wear-Resistant Superhydrophobic Coatings for Wind Power Systems" (T/CITS 420—2025). The issuance of this standard fills a gap in the technical requirements for wear-resistant superhydrophobic coatings in wind power systems, providing the industry with a unified technical basis and helping to enhance the performance of wind power equipment and promote its standardized development.

01 Standard Highlights
🔹 Comprehensive coverage of performance metrics

The standard specifies various technical requirements for wear-resistant, superhydrophobic coatings used in wind power systems, including 12 key indicators such as initial water contact angle (≥150°), rolling angle (≤10°), abrasion resistance, anti-icing performance, and adhesion. These requirements ensure that the coating maintains excellent performance even under extreme environmental conditions.
🔹 Rigorous testing methods
The standard provides detailed test methods for various performance characteristics—for example, the abrasion resistance test is conducted according to GB/T 1768-2006, and the anti-icing performance is evaluated by recording the delay in ice formation using a high-speed camera, ensuring that the test results are scientifically sound and reliable.
🔹 Environmental protection and safety are equally important.
The standard explicitly requires that the production and application of coatings comply with the limits on hazardous substances specified in GB 30981, thereby ensuring safety for humans, living organisms, and the environment.
🔹 Clearly defined scope of application
The standard applies to the production, design, and inspection of coatings for critical components such as wind turbine blades, providing clear technical guidance for wind equipment manufacturers and coating companies.

02 Standard Significance
As a national-level high-tech enterprise, Hissen-Mech leverages its state-level laboratory and a research and development team of over 100 members to transform more than a decade of accumulated expertise in wind power materials into industry-wide consensus. This standard establishes specifications based on key parameters such as water contact angle, rolling angle, coating thickness, wear resistance testing methods, ice adhesion strength, acid resistance, and alkali resistance, thereby promoting the standardization and industrialization of protective technologies for wind power equipment.
🔹 Enhancing Equipment Durability: By standardizing the technical requirements for wear-resistant, ultra-hydrophobic coatings, we can significantly extend the service life of wind power equipment in harsh environments and reduce maintenance costs.
🔹 Promoting Industry Standardization: The release of standards addresses the issue of inconsistent technical standards within the industry, thereby fostering the standardization and high-quality development of coating technologies.
🔹 Supporting the development of clean energy: Providing technical assurance for the reliable operation of wind power systems and further promoting the widespread adoption and application of clean energy worldwide.
