  • Respirator, welding helmet, or face shield that has low surface energy hard-coat lens
    Patent number: 8015970
    Abstract: A personal safety protective device that includes a lens and a support structure onto which the lens is secured. The lens includes a substrate and a hard-coat layer located on the substrate of the lens. The hard-coat layer has a low surface energy outer surface that is derived from a) an additive that includes at least one of i) a perfluoropolyether urethane that includes hydrolysable silane groups, and ii) an acrylate polymer that includes at least one perfluoropolyether moiety and at least one hydrolysable silane group, and b) a silsesquioxane-based hard-coat composition. The provision of such a lens on a personal safety protective device enables the lens to be durable to abrasion and to be easily cleaned without use of solvents that could shorten the service life of the lens.
