The anti-corrosion coating project for the embankments along the Suzhou River and the Huangpu River—a landmark infrastructure project of the Shanghai World Expo—has recently completed its 10-year performance monitoring. Monitoring data confirms that the surface coating on these embankments, which are subjected to daily tidal fluctuations, high levels of salt spray and a hot, humid environment, has retained its original performance to this day, setting a new global benchmark for ‘permanent protection’ in hydraulic engineering.

In 2021, the Shanghai Sino-Finnish Thermal Power Plant set out a clear requirement: it would no longer accept solutions that ‘last a year with a single coat’, but instead sought to establish a concrete repair system capable of ‘withstanding corrosion reactions over the long term, with the inner layers of the structure able to self-seal micro-cracks’. This represented not only a head-to-head challenge in materials technology, but also a redefinition of industry standards.

In 2019, a sulphur tank operating at high temperatures within the Storage and Transportation Department of Shanghai Petrochemical suffered severe corrosion and damage. With the tank operating year-round at temperatures as high as 135–165°C, the traditional protective coating had peeled away over large areas, putting the tank’s protective system at risk of failure. To prevent safety incidents and ensure uninterrupted production, the client initiated an emergency repair project and, for the first time, adopted the Keeper Materials nano-repair material system.

Developing a Synergistic Protection Technology Model Integrating Concrete, Coatings and Structures Promoting a shift in high-speed rail infrastructure maintenance philosophy from ‘repairing damage’ to ‘preventing potential hazards and extending service life’

The efficient execution of this emergency repair ensured the production continuity of Sinopec Shanghai Petrochemical Co., Ltd.'s Refining Division, earning high recognition from the client.

Keeper utilizes the latest acid-free rust conversion technology and concrete nano-repair technology to restore the condensation system, significantly extending its service life.
