Physical Properties for Lexan* MR10 Sheet

Lexan* MR10 Sheet
Description
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.
