Epoxy high-temperature anticorrosion coating

I. Product Introduction: Epoxy high-temperature anticorrosion paint is a special paint designed for high-temperature and highly corrosive environments. It utilizes the excellent properties of organosilicon resin and epoxy resin, combined with specific curing agents and additives, to form a tough, heat-resistant protective layer that effectively resists the erosion of external corrosive media. Its main characteristics include excellent heat resistance, corrosion resistance, wear resistance, strong adhesion, and good mechanical properties. It can maintain its protective effect for a long time under harsh conditions such as high temperature, high humidity, and strong corrosion, and is widely used in equipment protection in the petroleum, chemical, power, and metallurgical industries. II. Main Components and Their Functions: The main components of epoxy high-temperature anticorrosion paint are based on organosilicon resin and epoxy resin, combined with special curing agents, pigments, and fillers, etc. Through careful design and preparation, a unique anticorrosion system has been formed. The main function of this paint is to provide long-term and effective protection for various substrates under harsh conditions such as high temperature and strong corrosion. Organosilicon resin: As the main film-forming substance of the paint, it can form a protective film on the surface of the substrate, which has good high-temperature resistance and can effectively prevent the oxidation and corrosion of the substrate in high-temperature environments. At the same time, organosilicon resin also has good adhesion and wear resistance, which can enhance the stability and durability of the coating. Epoxy resin: As the main film-forming substance of the paint, it provides good adhesion and corrosion resistance. Curing agent: Reacts chemically with the epoxy resin to form a strong protective layer on the surface of the substrate. Pigments and fillers: Give the paint color and texture, while enhancing the weather resistance and corrosion resistance of the coating. Additives: Such as leveling agents, defoamers, and anti-settling agents, are used to adjust the application performance and storage stability of the paint. III. Product Features: Excellent heat resistance: It can work for a long time in environments up to hundreds of degrees Celsius without failure, ensuring the long-term stability and safety of the substrate. Excellent anticorrosion performance: By forming a dense protective film, it effectively isolates the corrosive medium from the substrate, greatly extending the service life of the substrate. Good chemical stability: It can resist the erosion of various chemical substances such as acids, alkalis, and salts, maintaining the integrity and functionality of the coating. IV. Application Range: Epoxy high-temperature anticorrosion paint is widely used in the petroleum, chemical, power, metallurgy, and aerospace industries. For example, in the petroleum and chemical industry, it is often used for the protection of equipment such as storage tanks, oil pipelines, and reactors; in the power industry, it can be used for high-temperature corrosion protection of equipment such as boilers, steam turbines, and generators. It can also be used for chimneys, flues, high-temperature hot gas pipelines, heat exchangers, and other metal surfaces requiring high-temperature corrosion protection. Through the analysis of practical application cases, we can find that epoxy high-temperature anticorrosion paint has shown excellent anticorrosion effect and service life in these fields. V.

Construction Reference 1. Before construction, the metal surface should be degreased, derusted, and cleaned of dirt to improve the adhesion of the coating (preferably after sandblasting); 2. Construction ratio [5 kg paint: 1 kg curing agent: about 3 kg thinner] 3. Xylene can be used as a thinner. Air spraying is preferred, but brushing can also be used, but it is not easy to dry; 4. If sedimentation is found during storage, stir well before use; 5. Poor gasoline resistance, pay attention during construction.   VII. Transportation and Storage 1. The product should be waterproof and sun-proof during transportation, avoid collisions, and comply with the relevant regulations of the transportation department; 2. The product should be stored in a cool and ventilated place, away from direct sunlight, and isolated from fire sources and heat sources;   VIII. Safety Protection The construction site should have good ventilation equipment, and operators should wear protective equipment such as glasses and gloves to avoid skin contact and inhalation of paint.
