Abstract: Compositions and coatings for thin films designed to protect surfaces and windows from environmental abrasion (e.g., sand, dust, and rubbing) that are transparent in visual and infrared wavelengths are disclosed. The compositions comprise thiol-containing copolymers comprising: (1) 10-(3-butyl-2-hexyl-6-(9-mercaptononyl)cyclohexyl) decane-1-thiol; and (2) a multifunctional terminally unsaturated hydrocarbon monomer; wherein (1) and (2) are combined to form a UV curable crosslinked thermoset polymer network and no particulate fillers are added to the composition. The films exhibit a specular transmission of greater than 70% in the visual spectrum at about 400-700 nm, and IR wavelengths at about 4-5 ?m, and about 7.5-12 ?m when applied to a surface of a substrate in a coating thickness of about 1-500 ?m. A method for making the films involving an UV initiated thiol-ene curing mechanism is also provided.

Abstract: A mirror is shaped using a shaping apparatus including a crossbar and a horizontal array of members (wheels in some embodiments) attached to a bottom of the crossbar. The height of the array of members is adjusted to form a predetermined shape. The shaping apparatus is positioned over a mirror such that the members contact the mirror. The shaping apparatus is moved along a length of the mirror such that the members remain in contact with the mirror. A frame is attached to the mirror such that when the shaping apparatus is removed from the mirror, the mirror substantially retains the predetermined shape.
