FEVE fluorocarbon paint

The fluorocarbon coating developed by the company is a new type of thermosetting coating for precoated coil based on Japanese Daikin's polytetrafluoroethylene as the main film forming substance. It is far more than other film forming substances in the coating weather resistance, hardness, stain resistance, acid and alkali resistance, which is the king of modern outdoor building decoration materials; The excellent performance of FEVE fluorocarbon coating is due to the special chemical structure of the product. Due to the strong bond energy of carbon-fluorine bond (485KJ/mol), only a small proportion of ultraviolet light in sunlight (≤220nm ultraviolet wavelength) can destroy C-F bond. The sunlight almost has no effect on the fluoropolymer, so the fluoropolymer has ultra-high weather resistance.
