Heavy-duty anti-corrosion paint series for the inner wall of water-based petroleum storage tanks
Matching performance
Good anti-corrosion ability to meet the protection requirements of the entire coating;
No toxic and harmful substances are produced in the dispersion medium, construction process and coating film forming process, which meets the requirements of environmental protection; dual composition, good hardness, good adhesion, resistance to various oils, and excellent chemical resistance;
The matching is good, the coating film is firmly attached to the metal substrate, which can enhance the adhesion of the upper coating film; the construction in the tank can appropriately increase the lighting voltage without fire hazards and ensure the construction quality.
Application range
Non-conductive products are suitable for coating protection of parts that do not require static electricity, such as crude oil tanks and floating roofs.
Coating protection of the inner wall of cans, etc. Conductive products are suitable for the inner wall of finished oil storage tanks (diesel, kerosene, volatile oil, various gasoline, etc.) and other coating protection with anti-static requirements
Surface treatment
All surfaces to be coated should be free of oil and dust and should be kept clean, dry and free from contamination and all surfaces should be evaluated and treated according to ISO8504:1992. It is required to reach the Sa2.5 level, and the primer should be applied within 6 hours after sandblasting.
Construction Description
High pressure airless spraying is recommended to obtain a uniform and good film.
Mix evenly according to the proportion. If the viscosity is too thick, it can be diluted with water to the construction viscosity. In order to ensure the quality of the paint film, we recommend that the dilution amount is 0%-5% of the original paint weight. The relative humidity is less than 85%, and the construction surface temperature is greater than 10°C and greater than the dew point temperature by 3°C.
