Fluorocarbon coating is a kind of high-performance coating. Its main components are fluororesin and carbon pigment, and it has excellent characteristics such as weather resistance, chemical corrosion resistance and abrasion resistance. Fluorocarbon coatings are suitable for surface coating of various buildings, industrial facilities, vehicles, etc., such as airport terminals, large industrial equipment, automobiles, aircraft, etc., and can provide excellent anti-corrosion, anti-rust, anti-pollution effects, etc., and have a long service life and maintenance cycle.
