Mar/UV-resistant Lexan™ MR10 sheet combines the impact strength of Lexan™ polycarbonate sheet with proprietary abrasion/UV resistant surface that approaches glass in performance. Lexan™ MR10 Sheet with Margard coating backed by a ten-year limited warranty against yellowing, abrasion resistance, breakage, loss of light transmission, and coating failure£.) Lexan™ MR10 sheets unique coating is graffiti-resistant enabling restoration to a like-new condition. In addition, Lexan™ MR10 sheets offer improved resistance to weathering as well as forced-entry protection. It is an excellent candidate for use in stores, public buildings, schools, bus shelters, and other high traffic areas. Lexan™ MR10 sheet is for transparent applications only. Because of its high mar-resistant surface, paint, adhesive, and other materials will not adhere to its surface. The coating is applied to both sides, therefore helps eliminate second-surface decoration. Also due to its mar-resistant coating, Lexan™ MR10 sheet cannot be cold formed.
