Description

Technical Field

[0001] The utility model relates to the field of coatings, in particular to a corrosion-resistant alkyd topcoat coating. Background Art

[0002] After the oil-based paint is applied to the surface of the protected object and solidifies, a paint layer will be formed. In order to enhance the performance of the coating and increase its practicality, we generally apply several layers of paint on the surface of the protected object to form a paint layer structure to meet the needs of users. The existing ordinary industrial anti-corrosion paints have poor corrosion resistance in oil, acid and alkali, and salt spray environments during use, and have poor wear and impact resistance and water and penetration resistance. They are easy to fall off after long-term use. Therefore, it is urgent to develop a corrosion-resistant alkyd topcoat coating that has excellent penetration resistance, mildew resistance, moisture resistance, and medium corrosion resistance, as well as good wear and impact resistance.
