10 January report: corrosion is a worldwide problem. The source reports annual global losses of USD 700 billion, equivalent to 2-4% of global GDP and six times the losses from earthquakes, typhoons, floods and other natural disasters. It states that corrosion-related steel scrap equals approximately 25-30% of annual global production, and that serious accidents from corrosion impede economic development.Pending confirmation

Anti-corrosion coatings are important in industry, transport, energy and marine engineering. A protective film can improve resistance to mould, rust and heat. The source describes growing corrosion problems in petrochemicals, energy, power, metallurgy and aerospace, including severe corrosion, and states that higher national standards encourage coating research and production.

Compared with conventional paint, self-healing anti-corrosion coatings can repair damage to the coating and prevent corrosion from spreading.

The source describes Shandong Gewu New Materials developing Jufudun and passing technical inspections at the Chinese Academy of Sciences Institute of Metal Research and other institutions. It reports self-healing anti-corrosion performance and a planned 10-tonne-scale production line in April of the article's year.Pending confirmation

The source describes Shandong Gewu New Materials Technology Co., Ltd. as a specialist developer and seller of self-healing anti-corrosion coatings that entered the Weifang military-civilian intelligent equipment industrial park in August 2017. It reports cooperation with the Chinese Academy of Sciences Institute of Process Engineering in a coating laboratory and development of the Jufudun self-healing anti-corrosion paint additive.Pending confirmation

The source describes Jufudun as a green, non-toxic microcapsule self-healing anti-corrosion paint additive inspired by biological repair. When a coating cracks or suffers mechanical damage, capsules break and release a repair agent, forming a new protective layer. It claims rapid restoration of coating and interface protection, corrosion resistance under complex conditions and extended material life.

A Shandong Gewu representative states that Jufudun was developed with environmental performance as a priority. Non-toxic self-healing particles replace additives such as hexavalent chromium salts. The source describes compatibility with water-based paint to improve corrosion resistance while retaining environmental benefits and reducing risks to people and the environment.

The source describes substantial corrosion losses in marine engineering, transport, machinery and energy. It claims that Jufudun can extend metal equipment life and maintenance intervals, control repair costs and economic losses, and reduce corrosion-related accidents.

Self-healing additives influence anti-corrosion coating protection and life. The source anticipates that Jufudun development could support further advances in industrial corrosion protection.
