What is the important direction of optical film research? Source: protective film factory direct sales Release time: 2019-06-13 Click: 1366 Optical film substrates are generally flat and flawless, with high gloss and light transmittance, low haze, and coating Good performance and so on. However, if the surface of the substrate is flat and defect-free, there are fewer active points in contact between the coating and the surface of the film substrate, which makes it difficult for the coating liquid to penetrate and form adsorption with it; if the substrate gloss and light transmittance are high , The surface roughness of the substrate is low, resulting in fewer bonding points between the coating liquid and the surface of the film substrate. At the same time, the PET polyester film has its own characteristics, such as the highly oriented crystals on the surface of the PET film, which makes it difficult for the coating molecules to penetrate into the PET film, and it is also difficult to form a good interface adhesion with the coating. Therefore, when preparing PET optical films, solving the problem of interface bonding between the substrate film and the coating has become another important direction of optical film research. 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!
