VUEGUARD® 912 coating treatment is available as Water-Clear (WC) for plastic
sheets and molded articles, offering superior resistance to ultraviolet degradation and abrasion. While Vueguard 912® has been designed primarily for acrylic
(polymethylmethacrylate) substrates, other plastics may benefit from its application.
