Research status of PET optical thin film coating technology-technical knowledge

Current research status of PET optical film coating technology Source: Protective film factory direct sales Release time: 2019-10-26 Click: 1481 The coating technology of PET optical film is the key technology of optical film. According to Coating Online, coatings can be divided into three categories according to their role, namely 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, increase 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 a liquid crystal display. The internal scattering caused by the difference in refractive index of the particles can prevent the effect of tailing of the picture and so on. The technologies related to coating mainly include coating formulation technology, coating curing technology and coating process technology. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 20 years of experience. It can produce PET film with various 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, optical PET film, etc. Interested parties welcome to inquire!
