    Abstract: Transparent edge sealed window films substantially minimize (if not eliminate entirely) degradative effects on the window film, particularly solar-reflecting metals and/or oxides associated with multilayer window films, caused by ambient conditions (e.g., commercial window cleaners, salt and the like). The edges of window films are preferably sealed by a liquid solvated polymeric material which, upon curing, provides a solid transparent seal which significantly minimizes the degradative effects of the ambient environment. Most preferably, the window film whose edges are sealed will include a transparent thermoplastic (e.g., a polyester) film layer and a solar-reflecting metal and/or oxide applied onto a surface of the film layer. The sealant for such a preferred window film will be a polyester-type sealant which has silane end-group functionality and substantially no free isocyanate groups.

    Abstract translation: 透明边缘密封窗膜基本上最小化(如果不是完全消除)对由环境条件(例如,商业窗户清洁剂,盐等)引起的窗膜,特别是与多层窗膜相关的太阳能反射金属和/或氧化物的降解作用 )。 窗膜的边缘优选通过液体溶剂化聚合材料密封,其在固化时提供固体透明密封,其显着地最小化周围环境的降解作用。 最优选地,其边缘被密封的窗膜将包括施加到膜层表面上的透明热塑性(例如聚酯)膜层和太阳能反射金属和/或氧化物。 用于这种优选窗膜的密封剂将是具有硅烷端基官能团并且基本上不含游离异氰酸酯基团的聚酯型密封剂。

    Abstract: This invention relates to film composites with a single coating of hard coat material which have a significant improved adhesion together with improved weather resistance while also increasing resistance to abrasion and cracking. In one embodiment, this film composite is comprised of a transparent base sheet having on one side thereof a weather resistant hard coat comprised of: at least one multifunctional acrylate monomer or oligomer; a dual-curable resin comprising an aliphatic urethane acrylate resin having isocyanate functional groups and an aliphatic urethane acrylate having hydroxyl functional groups; an ultraviolet (UV) stabilizer; and a photoinitiator.
