What is the water-based coating liquid for optical polyester film? Source: Protective film factory direct sales Release time: 2019-10-31 Hits: 2369 A water-based coating solution for optical polyester film is used on the PET polyester film. The water-based coating solution contains 1.5%wt of polyester. Resin, 1.0%wt melamine resin, 5.0%wt acrylic resin and a small amount of surfactant. After coating, the obtained polyester film has high transparency, low haze, excellent adhesion and slipperiness, and is suitable for substrates for optical applications such as diffusion films and brightness enhancement films. Coating the PET polyester film with a coating solution containing acrylic adhesive, silicon-containing wetting agent, colloidal silica, and melamine hardener, the PET film and the post-processing layer have excellent adhesion strength , More suitable for optical film use. According to Coating Online, there are many factors that affect the bonding strength of the interface, such as interface residual stress, coating thickness, curing temperature, curing time, and post-curing.
