Huaren Chemical Industry Co., Ltd. has been a trusted name in the chemical industry since 1994. Specializing in the production of various resins and industrial paints, we are proud to supply high-quality products at competitive prices.

Anti-corrosion primers can be divided into the following types according to their composition, function and application occasions: 1. Epoxy anti-corrosion primer 2. Polyurethane anti-corrosion primer 3. Zinc powder anti-corrosion primer 4. Alkyd anti-corrosion primer 5. Water-based anti-corrosion primer

Based on the above classification, we can clearly say that epoxy primer is indeed a type of anticorrosive paint. Epoxy primer not only has the adhesion enhancement effect of general primers, but more importantly, it plays a vital protective role in the anticorrosion system.

Main types of steel anti-corrosion coatings： 1. Epoxy anti-corrosion coatings 2. Polyurethane anti-corrosion coatings 3. Zinc-rich anti-corrosion coatings 4. Inorganic zinc silicate coatings 5. Asphalt-based anti-corrosion coatings 6. Polyurea anti-corrosion coatings 7. Acrylic anti-corrosion coatings

Anti-corrosion coating is a type of coating specially used to protect the surface of materials from corrosion. It is mainly used for the protection of materials such as metals, concrete, and wood. Epoxy anti-corrosion coatings are anti-corrosion coatings made of epoxy resin as the main film-forming substance, with excellent mechanical properties, adhesion and chemical stability.

If the budget is sufficient and long-term protection is required, zinc primer is the best choice. Otherwise, for some projects with medium protection requirements, oxidation primer is also a good economic choice.

● Leisure yachts: Usually used in freshwater or coastal waters, antifouling paint can effectively keep the bottom of the ship clean and improve navigation efficiency. ● Commercial ships and fishing boats: Long-term sailing at sea, antifouling paint is a necessity, which can significantly reduce maintenance costs and fuel consumption. ● Sailing and rowing boats: The speed requirement is high. Antifouling paint can reduce the resistance of the bottom of the ship and increase the speed.

In some industrial environments, chemicals such as acids, alkalis, and chemical solvents can corrode metals. If the primer does not have sufficient chemical corrosion resistance, the chemicals may penetrate through the coating to the metal surface, causing rust.

Zinc-rich primer prevents steel corrosion through the anodic protection of zinc, which is an electrochemical protection. The epoxy primer forms a dense shielding layer to isolate moisture and oxygen and prevent the oxidation of the substrate, which is a physical shielding protection.

Metal protective paint is a coating specially used to protect metal surfaces from external factors such as oxidation, corrosion, and wear. It forms a dense protective film on the metal surface to isolate air, moisture, and other corrosive media, thereby extending the service life of metal materials.
