The key technology of PET optical film--coating technology

According to coating online understanding, according to the role of the coating, the coating can be divided into three categories, namely protective coating, decorative coating and functional coating.
Films with different functions can be prepared by coating different coatings on the PET polyester film. For example, the anti-scratch and anti-static coating is coated on the surface of PET polyester film to make a screen protective film, which is used to protect the surface of mobile phone or computer screen;
On the PET polyester film, coated with a coating containing optical particles or glass beads, it can be made into an optical diffusion film, which can be used in the backlight module of the LCD panel, which can effectively eliminate the phenomenon of light and dark interlacing or dots, improve the brightness of the light, and make the The light emitted by the light guide plate is softened and diffused to provide a uniform surface light source for the LCD panel;
Coating a resin system with particle components on the surface of PET polyester film can be made into an anti-glare film, which is used for liquid crystal display screens, and has the internal reflection caused by the scattering of reflected light and the difference in refractive index between the hard-coated resin and the particles. Scattering to prevent the effect of picture smearing and so on.
Coating-related technologies mainly include coating formulation technology, coating curing technology and coating process technology.
