polyva takes you to understand that different coatings have different characteristics. Source: protective film factory direct sales Release time: 2019-06-15 Hits: 1464 Coating a layer of fluorosiloxane graft polymer and ultraviolet rays on a transparent film substrate The hard coat layer of the resin is cured, and the hard coat layer is subjected to an alkali saponification treatment. After performance test, its pencil hardness can reach 2H~8H. When high refractive index siloxane is used for the coating, it can be used as the base coating of the anti-reflection film. Add nitric acid to the composition of sodium acetate, tetraethoxysilane, methyltriethoxysilane, isopropanol and ethanol, and carry out a catalytic reaction for 2h to obtain silica sol, which can be used as a wear-resistant and scratch-resistant coating . Methacryloxypropyltrimethoxysilane, hydrolyzed polymer product is used as the main film-forming material, and TEOS hydrolyzed silica sol is introduced as an inorganic reinforcement to adjust the pH value of the two mixed solutions. The copolycondensation reaction between the two hydroxyl groups is used to prepare an organic/inorganic composite transparent wear-resistant coating on the surface of the substrate. For the use of γ-glycidoxypropyltrimethoxysilane (KH-560, industrial grade), ethyl orthosilicate (TEOS, CP grade) and diethanolamine as the main raw materials to prepare silicone anti-fog and wear-resistant coatings , And conduct performance research. The results show that the obtained coating has excellent haze, abrasion resistance, transparency, adhesion and crack resistance. The surface is uniform and flat. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 10 years of experience. It can produce PET film with multiple functions, such as: sub-(mist) surface PET film, flame-retardant (fire-resistant) PET film , Inkjet printing film, anti-static PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, etc. Interested parties welcome to inquire!
