In recent years, smart phones, tablet computers and wearable electronic products have become quite popular, and have developed into People's Daily necessities and travel necessities. However, how to make the touch screen of mobile phones, computers and other electronic products anti-fouling fingerprint, sweat stains or oil pollution, has become an urgent problem to be solved.


Fingerprint components generally consist of sweat, sebum (triglycerides, monoesters), a small amount of dead skin cells and dust. Therefore, to prevent fingerprints, the processed touch screen must be both water-resistant and oil-resistant.


The touch screen treated with perfluoroalkyl silane, perfluoropolyetheryl silane, fluoroalkyl silicone resin, fluoroalkyl substituted polysiloxane, perfluoroalkyl polyacrylate, perfluoroalkyl polyacrylate-polyurethane copolymer and so on can be given anti-fouling and anti-fingerprint properties. Among them, perfluoroalkyl polyacrylate and perfluoroalkyl polyacrylate - polyurethane copolymer are mainly used for anti-fingerprint of galvanized sheet of home appliances, back plate of mobile phone and computer, etc., while fluorosilane and fluorosilicone resin are mostly used for processing of glass substrate such as touch screen due to their high hardness and good transparency.


In addition, fluorosilane, fluorosilicone resin, etc., can be used to construct a hydrophobic film similar to the effect of lotus leaf, and further improve the anti-fouling and anti-fingerprint effect. If the fluorine containing acrylic/silicone resin or epoxy fluorine silicone resin, fluorine containing siloxane oligomer and nano pigment, nano SiO2 composite nano-coating, spraying on the surface of the substrate such as household appliances, curing can not only obtain a high degree of finish, transparent film, and the film can show good anti-fouling and anti-fingerprint effect.






Containing fluorine silicone oil refers to methyl silicone oil side group replaced by fluoride group of silicone oil products, such as three fluorine propyl, it combines the dual nature of the organic silicon and fluorine, has excellent weather resistance, high and low temperature resistance, chemical stability and waterproof paint, can be used as lubricant, defoaming agent, surface treatment agent, release agent and additives, etc., Used in aircraft, automobile, machinery, chemical industry, textile and other fields.
