Process Features: The KANA coating liquid protects the printed patterns, extending the service life of the patterns by more than 3 years. It eliminates cracking issues, features excellent ductility and flexibility, and can be folded repeatedly without breaking. It delivers outstanding friction resistance and damage resistance, great yellowing resistance, rainproof and mildewproof performance, high temperature resistance, low temperature resistance, and strong aging resistance. The formed protective layer effectively isolates oxidation and blocks direct ultraviolet radiation. It can improve the weather resistance of printing inks by more than 3 years — for example, when using original EFI/Canon inks, the color fading and chromatic aberration performance remains excellent after 5 years. It has obvious cost advantages, is convenient for installation and construction, and the pattern surface is bright, smooth and easy to clean.
