Take you to understand the research status of PET-type optical film coating technology. Source: Protective film factory direct sales Release time: 2019-06-12 Click: 1849 The coating technology of PET-type optical film is the key technology of optical film. According to Coating Online, coatings can be divided into three categories according to the role they play: protective coatings, decorative coatings and functional coatings. Coating different coatings on PET polyester film can produce films with different functions. For example, the surface of PET polyester film is coated with anti-scratch and antistatic (106~108Ω) coating to make a screen protection film, which is used to protect the surface of mobile phone or computer screen; on PET polyester film, the coating contains The coating of optical particles or glass beads can be made into an optical diffusion film, which can be used in LCD panel backlight modules, which can effectively eliminate the phenomenon of light and dark interlacing or dots, improve the brightness of the light, and soften the light emitted by the light guide plate. The LCD panel provides a uniform surface light source; the surface of the PET polyester film is coated with a particle-based resin system, which can be made into an anti-glare film, which can be used in liquid crystal displays. The internal scattering caused by the difference in refractive index of the particles prevents the effect of tailing of the picture and so on. Coating-related technologies mainly include coating formulation technology, coating curing technology and coating process technology. Foshan Bowei Environmental Protection Material Co., Ltd. is a supplier of electronic materials with 10 experiences. It can produce PET film with multiple functions, such as: sub-(matte) 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!
