Only 1 passed the rigorous audit! This domestic paint, won the core of high-speed rail exclusive supply rights.

This procurement project finally adopts the direct procurement mode. The core reason is that only one supplier of Xiangjiang coating products meets all the technical and supply standards. The EMU bogie, as the key steel structure to vehicle load-bearing and traction braking transmission, has stringent operating conditions. At a maximum speed of 350 km/h, it can face multiple erosion such as gravel impact, continuous vibration, high and low temperature alternation, rain corrosion, ultraviolet exposure and so on to a long time, which sets high standards to coating products protection and mechanical performance. Therefore, while the protection of general solvent-based products-based coatings in the sector is stable, however the high VOCs releases do not meet the direction of environmentally friendly manufacturing transformation of rail transit, and most aqueous items are difficult to take into account the thorough indicators such as anti-stone impact, high adhesion, prolonged anti-corrosion and so on.

Relying on independent formula research and research, the core performance of Xiangjiang coating products aqueous track coating products is better than the sector's general standards, in full compliance with the Q/CR546.4-2016 EMU bogie coating products official specifications. The product has outstanding performance in key tests such as salt spray resistance, pull-off adhesion and gravel impact resistance of steel substrates, and can completely replace traditional solvent-based products-based coatings. At the environmental level, the low VOCs aqueous system reduces pollutant releases from the source, which is in line with the national dual-carbon policy and the general direction of environmentally friendly upgrading of rail transit equipment, and is suitable to the outdoor service needs of high-speed rail vehicles throughout their life cycle.

After 76 years of deep cultivation in the paint sector, Xiangjiang Paint was established in 1950 and has grown from a small regional paint factory to one of the world's top 100 paint benchmarking companies. Its product layout covers 18 major paint categories such as automobiles, rail transit, heavy corrosion protection, wind power and military sector. It has three core brands of Xiangjiang, Shuangta and HKP, and four modern production bases in Hunan and Henan, with greater than 2000 employees. The company has set up a perfect sector-university-research innovation system, jointly built a joint research and research base with Hunan University and other universities, and jointly built a joint laboratory with leading companies of construction machinery, rail transit and military sector. Holding multi-level R & D and testing platforms such as national aging resistance testing center, post-doctoral cooperative R & D center and provincial engineering methodology research center, the company has built an integrated innovation chain of basic research on raw materials, customized research and finished product performance testing.

The new material of the bidding party is a listed first-class subsidiary of CRRC's A- share company. It started in 1984 relying on the rubber laboratory of the former Zhuzhou Institute of the Ministry of Railways, focusing on the industrialization of polymer materials. Its business covers rail transit, wind power, automobiles and other fields. It has research and research and production bases in many overseas countries, with an internationalization index exceeding 40% and a revenue exceeding 21.4 billion yuan in 2025. It is the core supplier of vibration damping and protective materials to domestic rail transit.
