Its core components include polymers, nanomaterials and special additives. These components work together to form a dense protective film to effectively isolate corrosive media. Self-crusting pinhole eliminators have excellent anti-permeability, wear resistance and weather resistance, and can maintain stable performance in extreme marine environments for a long time.

The main characteristics of self-skin pinhole eliminator include the following aspects: First, its self-skin characteristic enables the material to automatically form a uniform protective layer during construction, without the need for complex construction processes, greatly improving construction efficiency. Secondly, the pinhole elimination function can effectively fill the tiny pores on the surface of the material and prevent corrosive media from penetrating, thereby significantly improving corrosion resistance. In addition, the self-crusting pinhole eliminator also has good adhesion and flexibility, which can adapt to the thermal expansion and contraction of different substrates, and reduce the cracking and fall of coatings caused by stress changes.

The mechanism of action of self-crusting pinhole eliminator mainly includes two aspects: physical barrier and chemical protection. In terms of physical barriers, self-crusting pinhole eliminator effectively isolates corrosion media such as seawater, oxygen and salt spray by forming a dense protective film, thereby delaying the corrosion process. In terms of chemical protection, the active ingredients in the self-crusting pinhole eliminator can be combined with goldChemical reaction occurs on the surface to form a stable passivation layer, further improving corrosion resistance.

Specifically, during the construction process, the self-skin pinhole eliminator first forms a uniform protective layer through the self-skin characteristics. This process mainly relies on the self-assembly capability of polymers, allowing the material to automatically spread on the surface of the substrate and form a continuous protective film. Subsequently, the pinhole elimination function plays a role, and through the synergy between nanomaterials and special additives, tiny pores on the surface of the material are filled to form a defect-free protective layer. This process not only improves the denseness of the coating, but also significantly enhances its anti-permeability.

During long-term use, the self-crusting pinhole eliminator continuously protects marine engineering structures from corrosion through dual physical and chemical protection mechanisms. The physical barrier effectively isolates corrosive media, while chemical protection further delays the corrosion process by forming a stable passivation layer. This dual protection mechanism allows self-crusting pinhole eliminators to exhibit excellent corrosion resistance in extreme marine environments.

The weather resistance test of self-crusting pinhole eliminator uses QUV accelerated aging test. The test results show that after 2000 hours of QUV test, the coating has no obvious discoloration, powdering and cracking, and has excellent weather resistance.

  5. Flexibility: Flexibility is an indicator to measure the coating’s ability to adapt to thermal expansion and contraction of substrates. The flexibility test of the self-crusting pinhole eliminator adopts a bending test. The test results show that after the coating is bent for 180 degrees on a shaft rod with a diameter of 1mm, there is no crack or peeling phenomenon, and it has good flexibility.
