The fluorine content is a critical factor affecting the corrosion resistance of fluorocarbon coatings. Currently, these coatings are primarily used in heavy-duty anti-corrosion projects and for steel structures and building facades, where high corrosion protection standards are required.
Fluorocarbon paint is a coating synthesized using fluorinated olefins as the primary monomer. Its fluorine content directly determines the coating's weather resistance, corrosion resistance, and self-cleaning properties. Typically, the fluorine content ranges from 18% to 22%, though it may vary by manufacturer and product model.
Regarding the national standard for fluorine content in fluorocarbon paint, China currently implements HG/T 3792-2014 "Fluororesin Coatings." This standard specifies clear requirements for indicators such as fluorine content, weather resistance, and acid-alkali resistance of fluorocarbon paint. Specifically, it mandates that the fluorine content must be no less than 18%, which is a fundamental requirement to ensure the performance of fluorocarbon paint.
The fluorine content significantly impacts the performance of fluorocarbon coatings in several ways: higher fluorine content improves weather resistance and extends service life; enhances corrosion resistance, offering better protection against chemical media such as acids, bases, and salts; and boosts self-cleaning properties, preventing dust and pollutants from adhering to the surface.
When selecting fluorocarbon coatings, consider overall performance metrics beyond fluorine content, such as adhesion, hardness, and gloss. The construction process and supporting system also significantly impact the final result.
The CASUL Fluorocarbon Topcoat in the Steel Structure Coatings Series uses high-quality fluororesin with a fluorine content meeting national standards to provide ultra-long-term weather protection for steel structures.
