New corrosion protection paint for steel: Building a ‘green Great Wall’ for steel structures

2025 07/26

Driven by the dual challenges of severe industrial corrosion and global ‘dual carbon’ goals, the field of material protection has achieved breakthrough progress. The National Materials Research Institute's Joint Innovation Team has recently successfully developed a new generation of high-performance nano-composite anti-corrosion coatings, establishing a ‘green Great Wall’ for the long-term protection of steel infrastructure.

Green Transition: Balancing Environmental Protection and Performance

The research team adopted an advanced water-based acrylic system, reducing volatile organic compound (VOC) emissions at the source and nearly eliminating harmful heavy metal content. This not only aligns with increasingly stringent environmental regulations but also provides higher safety guarantees for construction personnel and the surrounding environment. Project leader Professor Li Hua emphasized: ‘We are committed to finding the optimal balance between “stronger protection” and “less pollution,” which is the future direction of coating technology.’

The emergence of this new coating marks a significant technological leap toward self-reliance in China's high-end corrosion-resistant materials sector. It serves not only as a protective barrier for steel but also as a critical safeguard for the safe operation and sustainable development of infrastructure. In the future, as the material formulation continues to be optimised and application scenarios expanded, this ‘green Great Wall’ will extend to more major projects vital to national economy and people's livelihood, injecting enduring vitality into industrial equipment and urban resilience.
