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. For the use of γ-glycidoxypropyltrimethoxysilane (KH-560, industrial grade), ethyl orthosilicate (TEOS, CP grade) and diethanolamine as the main raw materials to prepare silicone anti-fog and wear-resistant coatings , And conduct performance research. The results show that the obtained coating has excellent haze, abrasion resistance, transparency, adhesion and crack resistance. The surface is uniform and flat, the pencil hardness can reach 3H~4H, and the contact angle with water is about 10°. A hard coat layer containing fluorine-siloxane graft polymer and ultraviolet curable resin is coated on the transparent film substrate. The weight ratio of fluorine-siloxane graft polymer and ultraviolet curable resin is preferably 0.05:100 ~5.00:100, and alkali saponification of the hard coating. After performance test, the pencil hardness can reach 2H~8H. When high refractive index siloxane is used for the coating, it can be used as the base coating of the anti-reflection film. Add nitric acid to the composition of sodium acetate, tetraethoxysilane, methyltriethoxysilane, isopropanol and ethanol, and carry out a catalytic reaction for 2h to obtain silica sol, which can be used as a wear-resistant and scratch-resistant coating . 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.
