Scope of application: not only for the coating of roll substrates such as solar cell OPV and perovskite solar cell PVK but also for the coating of polyimide slurry formula developed in the laboratory,OLED coating,optical film (brightness enhancement film,hard coat,polarizing film,diffusion film,etc.) are also applied to discontinuous substrates such as LCD glass substrate photoresist coating.
Applicable to low-viscosity to high-viscosity coating lines; the use of cemented carbide dies can resist damage to the dies by foreign objects; the thickness of the coating can be 1~30um and above; the substrate size can be coated from 0.3~5mm; There is a buffer tank with adjustable equal pressure and flow.
