The use of fluorocarbon coating as the finishing layer, the surface layer of the tetrafluorocarbon paint base contains the largest fluorocarbon bond in all compounds, with amazing chemical inertness, experimental data and more than 30 years of application practice has proved that whether it is ultraviolet rays, harsh climate, complex environment and other situations, there is no need to worry about the deterioration of the coating film, therefore, fluorocarbon coating has a very excellent ultra-long weather resistance; fluorocarbon coating surface energy is very low, the friction coefficient is very small, dust is extremely difficult to adhere, even if it is attached, it is only on the surface of the base layer, It does not form chemical or physical bonds, is easy to clean, and has a recognized self-cleaning function; Fluorocarbon coating has good impact resistance, scratch resistance, abrasion resistance, scrub resistance, and has a strong resistance to the penetration of oxygen, moisture and corrosive ions, and fluorocarbon coating is not eroded by most chemicals, including seawater and salt spray corrosion. Through automatic spraying or mixing of special equipment in the factory, the coating is uniform, the color is consistent, and it can exude a metallic texture effect, which is the best solution to replace aluminum curtain wall and aluminum-plastic panel curtain wall.
