Detailed explanation of PET-type optical film coating formulation technology-film supplier

Organosilicon coating organosilicon materials are generally composed of silicon-oxygen chain links as the basic structural unit. The side chain can be connected to various other organic groups through silicon atoms. Therefore, the structure contains both 'organic groups' and 'inorganic groups'. StructureOrganic silicon coatings are often used as transparent wear-resistant coating materials due to their good light transmittance. This kind of coating has sufficient flexibility and good bonding performance with the matrix material; there is no double bond in the main chain, so it is not easy to be decomposed by ultraviolet light and ozone, even if it is exposed to the outdoors for a long time or in an environment with high ozone concentration. Cracks and viscous creep will not occur, and physical and electrical properties are basically unchanged; resin-based silicone coating materials will not yellow even under strong ultraviolet radiation, and their color can remain unchanged for many years. Many scientific and technological workers have carried out research in this area. It is understood that if a variety of nanoparticles are introduced as reinforcements in the coating, the wear resistance and compactness of the coating can be further improved. Polyurethane coatings. In addition to a considerable number of polyurethane bonds, the polyurethane coating molecules also contain urea bonds, ether bonds, ester bonds, and allophanate bonds. The cured coating film has good wear resistance. It is a kind of coating material with excellent performance and wide application. Diffusion film can be prepared by coating a layer of resin coating on PET film and other substrates. It has the properties of good adhesion, fine and smooth hand feeling, strong scratch resistance and excellent corrosion resistance. By adding different particles to the coating, a diffusion film or a brightening film can be prepared.
