The PET optical film coatings used in the LCD field are classified according to the main resin used, mainly including silicone coatings, polyurethane coatings and acrylic coatings or their modified derivatives. Organic silicon 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 structures'. The special composition and molecular structure make it have the characteristics of organic matter and the function of inorganic matter. The organic silicon coating is often used as a material for transparent wear-resistant coatings due to its good light transmittance. This kind of coating has sufficient flexibility and good bonding performance with the base 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 the physical and electrical properties are basically unchanged; the resin-based silicone coating material will not yellow even under strong ultraviolet radiation, and its color can remain unchanged for many years. Many scientific and technological workers have carried out research in this area. According to Coating Online, if a variety of nanoparticles are introduced as reinforcements in the coating, the wear resistance and compactness of the coating can be further improved. Using methacryloxypropyltrimethoxysilane (KH570) hydrolysis polymerization product as the main film-forming material, introducing TEOS hydrolysis product silica sol as an inorganic reinforcement to adjust the pH of the two mixed solutions Value, the organic/inorganic composite transparent wear-resistant coating is prepared on the surface of the substrate by the copolycondensation reaction between the two hydroxyl groups. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service.
