The coating has the characteristics of aging resistance, good hydrophobicity, oil stain resistance and light release, and meanwhile, the hardness of the coating reaches 2H.

Description

technical field [0001] The invention relates to the technical field of fluorine material coatings, in particular to a hydrophobic light release fluorine material coating. Background technique [0002] With the rapid development of social economy, the requirements for various functional films are getting higher and higher. Fluorine-containing material coatings can not only be used in various home decoration, daily necessities, display and other industries; at the same time, they are also very useful in the adhesive tape industry. ; But at present, fluoroplastic materials are mainly imported; the price is high and the technical bottleneck is large; [0003] Therefore, it is imminent to develop a fluorine-containing coating with independent intellectual property rights. Contents of the invention [0004] The purpose of the present invention is to provide a hydrophobic light release fluorine material coating. [0005] For reaching this purpose, the present invention adopts f...
