The VueGuard® 801 anti-glare superhard coating treatment is available as Water-Clear (WC) for plastic sheets and molded articles, offering superior resistance to scratching and abrasion. While VueGuard® 801 has been designed primarily for acrylic (polymethylmethacrylate) and polycarbonate substrates, other plastics may benefit from its application.
