1, can be used under harsh conditions, and has a long-lasting anti-corrosion life, heavy anti-corrosion coatings in chemical atmosphere and marine environment, generally can be used for 10 years or more, even in acid, alkali, salt and solvent media, and It can also be used for more than 5 years under certain temperature conditions.
2, thick film is an important symbol of heavy anti-corrosion coatings. Generally, the dry film thickness of the coating of the anticorrosive coating is about 100 μm or 150 μm, while the dry film thickness of the heavy anticorrosive coating is 200 μm or more, and 500 μm to 1000 μm, or even as high as 2000 μm.
According to the US NACE standard [PR-01-76 (1983) modified version of Iten No.53105, the corrosion resistance performance of ZS-711 coating was evaluated. As a result, the test of 4000h salt spray test and 4000h damp heat test was successfully passed. The coating has excellent weather resistance, anti-aging, anti-radiation, abrasion resistance, impact resistance, high temperature resistance (400 ° C ~ 600 ° C), low temperature (-60 ° C), stable conductivity; its electrical resistivity can meet anti-static requirements, It also guarantees a long life of the coating.
3. Strong adhesion: the coating has strong binding force to the substrate. The coating composition contains hydroxyl group (-OH). The metal matrix provides positive ions, which can form chemical bond. With the help of coupling agent in the coating, even realize covalent The combination of chains. In the space network structure, the metal, metal oxide nanomaterials and rare earth oxide ultrafine powder contained in the coating composition help the coating form a dense interfacial transition layer, and its comprehensive thermodynamic properties match the matrix. .
4, efficient and convenient: simple construction, realizing the self-curing of inorganic coatings at room temperature, when the ambient temperature is 20 ° C, the relative humidity is less than 85%, the surface is dry for 15 min, and the drying is 2 h, which can ensure high-efficiency construction and achieve excellent salt spray resistance. , resistant to aging. The coating is self-healing, and the local scratches caused by external force can still be protected. The coating is not damaged by cutting and welding, and the coated welding does not affect the welding quality.
5. Flexible use:
Inorganic polymer anti-corrosion coating can be used alone or as an anti-corrosion low-layer coating in combination with organic paint. Single-layer inorganic polymer anti-corrosion coating can be used as epoxy primer, acrylic, polyurethane or chlorinated rubber. It is used in combination with topcoats such as asphalt and has strong adhesion.
