What are the characteristics of anti-corrosion coating materials?

1. Anticorrosion
It can be used in harsh conditions and has a long anti-corrosion life. Heavy-duty anti-corrosion coatings can generally be used for more than 10 years or 15 years in chemical atmospheres and marine environments, and can be used for more than 5 years at a certain temperature even in acid, alkali, salt and solvent media. Thick film is an important sign of heavy-duty anti-corrosion coatings. Generally, the dry film thickness of anti-corrosion coatings is 100 μm or 150 μm.
According to the American NACE standard [PR-01-76 (1983) revised edition Iten No.53105, the corrosion resistance of ZS-711 to the coating was successfully passed 4000h salt spray test and 4000h damp heat test test. The coating has weather resistance, aging resistance, radiation resistance, chemical resistance, impact resistance, high temperature resistance (400 ℃ ~ 600 ℃), low temperature (-60 ℃), and stable electrical conductivity; its resistance can meet the anti-static requirements and ensure the safety of the coating. Life.


2. Strong adhesion
The coating has a strong bond with the substrate, the coating composition contains hydroxyl groups (-OH), and the metal matrix provides positive ions, which can form chemical bond combinations with the help of the coupling agent in the coating, and even realize the combination of covalent chains. Under the maintenance of the space network structure, the metals, metal oxide nanomaterials and rare earth oxide ultrafine powders contained in the coating composition help the coating to form a dense interfacial transition layer, so that its comprehensive thermodynamic properties match the matrix.


3. Convenience
When the ambient temperature is low, the construction is simple, and the normal temperature self-curing of inorganic coatings can truly achieve 20 °C. When the relative humidity is less than 85%, the surface dry for 15 minutes and the hard dry for 2 hours can ensure construction and achieve excellent resistance to salt spray and aging. The coating is self-healing, the local scratches caused by external force can still be protected, the coating is not damaged by cutting and welding, and the welding of the coating does not affect the welding quality.


4. Flexible use
Inorganic polymer anti-corrosion coatings can be used alone or as low-layer anti-corrosion coatings and organic coatings, and single-layer inorganic polymer anti-corrosion coatings can be used as epoxy, acrylic, and polyurethane primers.
①Excellent anti-corrosion performance: good adhesion, good anti-corrosion performance and long service life.
②Excellent construction performance: It can be fully cured at room temperature, such as traditional anti-corrosion coatings, the construction is simple, and it can be operated even if you are not skilled (the main reason why chlorinated rubber heavy-duty anti-corrosion coatings can be widely used).
③Excellent environmental performance: the solid content of traditional solvent-based anti-corrosion coatings can only reach 50~60%, while the solid content of high-solid heavy-duty anti-corrosion coatings can reach 70%~80%, or even 90%~*, and the solvent is reduced by nearly half , showing good environmental performance.
