Fluorocarbon resin contains fluoropolymer and, in comparison with other polymers, has lower surface energy. Therefore when the fluorine-containing monomer or polymer is copolymerized or mixed with other monomers or polymers, the fluoropolymer will accumulate on the surface of the resulting polymer coating. It has superior properties (such as: high weather resistance, chemical resistance and solvent resistance). After decades of rapid development, the fluorine coating has been widely used in various fields such as construction, chemical industry, solar energy backsheet, electrical and electronic industry, machinery industry, aerospace industry and household goods.
