Hello, Welcome To ZINDN!

The third Belt and Road Forum for International Cooperation Press release

During the first briefing of the third "Belt and Road" Forum for International Cooperation on October 16 the Ministry of Natural Resources' International Cooperation Department and relevant unit leaders presented an overview of China's marine international cooperation with countries participating in the "Belt and Road" initiative. interconnected blue planet is not fragmented by oceans but united as a community with a shared future, where people from all nations share both prosperity and challenges. China's proposal to build a maritime community with a shared future emphasizes the global consensus on promoting harmonious coexistence between humanity and our oceans.

Corrosion hazards in high salinity and high humidity marine environments

Seawater, being highly conductive electrolyte solution abundant in chlorides and represents one of nature's most corrosive mediums that can cause severe corrosion in marine environments. Combined with mechanical agitation caused by sea winds, waves, and strongvection currents, it generally believed that seawater becomes saturated with hydrogen unless under special circumstances ordinary steel materials are prone to degradation due to spoilage occurrence; however, such spoilage often remains concealed making it detect through regular preventive measures. This undoubtedly poses to the safe operation of large steel structures like land wharfs, offshore platforms bridges, port machinery readiness etc., leading to incalcul economic losses. Therefore, given the current scenario characterized by extensive port project construction activities taking place globally today,it address anticorros measures for steel structures within marine environments so as to proactively prevent potential issues before they arise.

A Two Component High Solids High Build Paint, Excellent Resistant To Seawater, Chemicals, Wear And Cathodic Disbandment

2K high build epoxy barrier coating and low VOC.

Long-term protection is provided by single layer. Glass flakes contained in the paint film can provide better anti-corrosion protection performance.



Excellent adhesion & anti corrosion performance, excellent cathodic disbandment resistance.
Excellent abrasion resistance.

Outstanding water immersion resistance; good chemical resistance.

Excellent mechanical properties.

Marine heavy anti-corrosion coatings, like all other epoxy paints, maybe chalk and fade for long time exposure in the ambient atmosphere. However, this phenomenon does not affect the anti-corrosion performance.

DFT 1000-1200um could be reached by single layer, it will not affect adhesion and anti-corrosion performance. This will simplify application procedures and improve efficiency.

For general use, film thickness suggested is between 500-1000 um.


Recommended use

To protect steel structures in heavy corrosive environments, such as underwater areas of offshore structures, pile structures, outer wall protection of buried pipelines, and steel structure protection in environments such as storage tanks, chemical plants, and paper mills.

Adding suitable non-slip aggregate can be used as a non-slip deck coating system.

Single coating can reach to a dry film thickness of more than 1000 microns, which greatly simplifies the application procedures.


Surface Treatment

Sandblasting to clean the surface to Sa2.5 (ISO 8501-1:2007) level or SSPC-SP10, surface roughness 40-70 microns (2-3 mils) is recommended. Surface defects exposed through the sandblasting should be sanded, filled in or treated in a suitable way.

The approved primer surface must be clean, dry, and free of soluble salts and any other surface contaminants. Unapproved primers must be completely cleaned to Sa2.5 level (ISO 8501-1:2007) by sandblasting.


Touch up:

It is suitable for coating on some firm and complete aging layer. But a small area test and evaluation is required before application.
