VueGuard 801® WC —— Superhard Water-Clear Coating

This VueGuard® 801 superhard water-clear coating treatment is available 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.
