Fluorocarbon coatings are PVDF resins, mainly referring to vinylidene fluoride homopolymers or copolymers of vinylidene fluoride and other small amounts of fluorine-containing vinyl monomers.
The chemical structure of the hydrofluoric acid base material is bonded by fluorine/carbon bonds. The stability and firmness of this chemical structure make the physical properties of fluorocarbon coatings different from ordinary coatings. In addition to the abrasion resistance and impact resistance in terms of mechanical properties, it has excellent performance, especially in harsh climates and environments, it shows long-term fading resistance and UV resistance. After high-temperature baking to form a film, the molecular structure of the coating is tight and has super weather resistance. Fluorocarbon coatings can be divided into traditional fluorocarbon coatings and nano-fluorocarbon coatings according to the surface film formation structure.
In 1965, Pennwalt Chemical Company of the United States first used fluorocarbon coatings to meet the needs of coating indoor and outdoor aluminum materials in high-end buildings. The wide choice of colors, the solemn appearance of the United States, and its durability have added luster to many magnificent curtain wall buildings around the world. Coating manufacturers guarantee the service life of coatings starting from 10 years, 15 years to more than 20 years. American research institutions have tested and compared fluorocarbon coatings, super coatings, and general coatings. The samples of the respective coatings were exposed to hot sunlight in Florida, USA, and exposed to the harsh environment of humid and salty air for 12 years. In 2010, it was actually proved that the stability and durability of fluorocarbon coatings were 30 E 80 percent higher than the other two coatings, and fluorocarbon coatings ensured the use in various harsh environments.
Color-coated aluminum coils are especially suitable for the decoration and display of indoor and outdoor decoration in public places, commercial chains, exhibition advertisements, eccetera.
