Product Description
Our Low Refractive Index UV-Curable Anti-Reflection Coating Liquid. It boasts excellent adhesion and stability on plastic substrates including PET, with little change in physical properties after aging tests. It can deliver film surfaces with good slipperiness and high water contact angle. Custom product development is available upon customer requests.
