At 9 am on October 24, the Hong Kong-Zhuhai-Macao Bridge was officially opened to traffic.
This super-large cross-sea transportation project jointly built by Guangdong, Hong Kong and Macao for the first time, with a total length of about 55 kilometers, is currently the world's longest cross-sea bridge and has the world's longest immersed tube submarine tunnel.
The construction of the bridge includes infrastructure, anti-rust, anti-corrosion, waterproof, and typhoon resistance.
Petrochemical products such as asphalt, paint, and waterproof materials have played a huge role in it.
The Hong Kong-Zhuhai-Macao Bridge is expected to have a service life of up to 120 years, which is 20 years longer than the current general life of the world's sea-crossing bridges.
This means that the bridge has a higher level of waterproof, rust-proof and anti-corrosion.
The anti-corrosion project of the Hong Kong-Zhuhai-Macao Bridge adopted the paint of COSCO Kansai Paint & Chemical Co.
, Ltd.
The anti-corrosion protection of the bridge concrete and internal steel bars uses Garboli's silane impregnating paint.
This paint is a high-purity undiluted isobutyl triethoxy silane, which can effectively prevent the substrate from corroding, loosening, peeling, and mildew due to water seepage, sunlight, acid rain and seawater erosion, and improve the service life of the bridge.

The submarine tunnel of the Hong Kong-Zhuhai-Macao Bridge is 6.
7 kilometers long.
It is the world's longest highway immersed tube tunnel and the only deep-buried immersed tube tunnel.
It is also my country's first offshore immersed tube tunnel.
The wall painting of the immersed tube tunnel uses Sankeshu engineering paint, which adopts a new generation of dairy technology, which can greatly improve the three functions of stain resistance, weather resistance and color retention.

In terms of waterproofing of the bridge, Dongfang Yuhong customized a waterproof system solution, and Supper Chemical was responsible for the polyurea waterproofing project of the immersed tunnel.

The Hong Kong-Zhuhai-Macao Bridge project spans the living water area of the Chinese White Dolphin, a national natural protected animal, and the marine hydrology and flood control sensitive area, which puts forward higher-level requirements for the quality, efficiency and environmental protection of production and construction.
As far as paint is concerned, it must be an environmentally friendly product and cannot cause any pollution to the environment and water bodies.
As the main paint supplier for the project, Jotun provides lead-free mercury-free, low-VOC paint products that fully meet the environmental protection requirements of the Hong Kong-Zhuhai-Macao Bridge.
