    Abstract: A method for improving adhesion of nonfogging film coatings comprising a block copolymer containing alternating blocks of polyurethane and a hydrophilic polyacrylic, to a polymeric substrate by subjecting the substrate to a controlled exposure to UV irradiation. Exposure may be prior to or following casting the nonfogging coating in place on the substrate. By varying the weight ratio of polyurethane/polyacrylic it is possible to vary the flexibility of the coating and hence to widen the range of substrates to which the coating may be applied, e.g., from flexible wrapping material to rigid mirrors.

    Abstract: An IOL injector that includes one or more polymeric portions that include a hydrophilic coating component that is effective to facilitate the passage of the IOL through the injector, particularly an injector tip. The IOL injector is prepared by a process that includes irradiating at least a portion of a polymeric, IOL injector with UV light in an environment comprising oxygen to provide a positive percent change in the atomic oxygen content of the polymer material at the surface as determined by X-ray Photoelectron Spectroscopy (XPS). A portion or the entire irradiated portion is then contacted with a solution comprising a hydrophilic coating component. The hydrophilic coating component is selected from a hydrophilic polymer, a hydrophilic copolymer or any one mixture thereof to provide a solution coated portion. The solution coated portion is then heated at a temperature to provide portions of the IOL injector with a shelf-stable, lubricious hydrophilic coating to facilitate delivery of an IOL from the injector.

    Abstract: The present invention provides a method of increasing the surface energy of an article having a polymeric surface increasing the relative amount of nitrogen atoms or oxygen atoms within a portion of the surface to form a nitrogen or oxygen enriched surface layer. The method of the invention is advantageously applied to a vehicle body frame to facilitate adhesion of a windshield. In another embodiment of the invention a method for inhibiting sealer redeposition is provided in which a plastic component in an automobile is treated prior to being subjected to the various paint preprocessing baths.
