Abstract
A process for preparing a hardcoated polycarbonate sheet involves (i) ultraviolet radiation curing an acrylic coating onto one surface of a flexible polycarbonate film via a drum casting technique to yield a flexible, abrasion and chemical resistant hardcoated film; and (ii) laminating the hardcoated film onto a thick rigid polycarbonate substrate by an on-line ultraviolet radiation lamination method. The process is fast, requires minimal labor and provides high optical quality hardcoats for polycarbonate sheet.
