Excellent adhesion, including adhesion tests across all possible operating temperature ranges of the equipment. It is divided into normal temperature, alternating cold and heat phases, and high-temperature operation phases. 2. It exhibits excellent mechanical properties under various temperature conditions, such as high temperatures, alternating hot and cold environments, and normal temperatures; its hardness, toughness, adhesion strength, etc., meet the required standards. 3. Corrosion resistance. The corrosion factors are determined based on the surrounding environment, such as industrial environments, buried conditions, and high-humidity river or marine environments, etc. Selection of high-temperature resistant anti-corrosion paint for industrial pipelines: 1. The inorganic zinc-rich primer is suitable as an anti-corrosion coating for the outer surfaces of pipelines at temperatures below 400°C; it can be used in combination with silicone-based high-temperature resistant topcoats. 2. Epoxy phenolic paint is used as a primer and topcoat for the anti-corrosion protection of the outer surfaces of carbon steel, cast iron, and stainless steel pipes at temperatures below 200°C; it is recommended for use on pipes with insulation layers. 3. The high-temperature resistant anti-corrosion paint for industrial pipelines is suitable for protecting the outer walls of pipelines operating at temperatures between 200 and 800°C; it can be used whether the pipelines have insulation layers or not
