The key technology of PET optical film-coating technology-technical knowledge

The key technology of PET optical film-coating technology source: protective film factory direct release time: 2019-11-02 click: 1537 According to the online understanding of coating, according to the role of the coating, the coating can be divided into three Types, 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 coating to make a screen protection film, which can be used to protect the surface of mobile phone or computer screen; on the PET polyester film, coating containing optical particles or glass micro The coating of the 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 light brightness, soften the light emitted by the light guide plate, and provide uniformity for the LCD panel. Surface light source; coating a resin system with particles on the surface of the PET polyester film, which can be made into an anti-glare film, which can be used for liquid crystal display screens. The generated internal scattering to prevent the effect of screen tailing 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.
