Abstract: A heat-treated titanium nitride film including a polymeric substrate and at least one titanium nitride layer is disclosed. The titanium nitride layer of the film is characterized by microscopic uniform generally parallel surface cracking in the machine direction of the film. The film is particularly useful as a solar control film suitable for application to a contoured transparent substrate with reduced or eliminated ghosting. A method for treating a titanium nitride film prior to application to a transparent contoured substrate and a method for applying a titanium nitride film to a transparent contoured substrate are also described.

Abstract: A packaged flexible film is described. The packaged flexible film includes (i) a cylindrical core having an outer surface; (ii) a supply of flexible film wound about the core with a leading edge adjacent the outer surface and forming a connection ridge along the outer surface; and (iii) a cover strip comprising a compressed compressible cover material covering said connection ridge. Also described are a packaging system for flexible film and a multilayer flexible film packaging tape.

Abstract: A coreless flexible film packaging system is disclosed. The system includes: (i) a containment cylinder including a cylindrical wall defining first and second cylinder end apertures and an interior film containment area; (ii) a film feed slot in the cylindrical wall extending longitudinally along the containment cylinder; and (iii) a supply of flexible film wound about itself to form a film roll having a central cylindrical cavity, said roll including a leading end and a terminal end and contained within the interior film containment area. A coreless containment package and a method for packaging a flexible film are also described.

Abstract: A vapor deposition device and a method for depositing a coating on a substrate are disclosed. The device includes a heating chamber for containing plasma and an evaporant chamber for containing an evaporant source. Evaporant is generated by heating of the evaporant source by the plasma. The heating chamber is both separated from the evaporant chamber and in thermally conductive connectivity with the evaporant chamber. The method includes supplying plasma to a heating chamber; heating an evaporant source by transfer of heat from the plasma to in an amount sufficient to generate evaporant from the evaporant source; and condensing the evaporant or a reaction product thereof on a surface of the substrate to form a coating thereon. The plasma is maintained in isolation from the evaporant source and the evaporant.

Abstract: An environmentally acceptable catalyst, coating system, and methods for thermal cure silicone release coatings that utilize bismuth (“Bi”) catalyst to retain properties of tin (“Sn”)-catalyzed systems but do not have the toxicity and environmental hazards associated therewith. The coating systems and methods also provide a laminate that shows reduced orange peel distortion over time compared with tin (“Sn”)-catalyzed systems and methods.

Abstract: An optical product for use in products such as window films and electronic displays is disclosed. The optical product includes a polymeric substrate and a hardcoat and has an abrasion resistance at the hardcoat surface as measured by haze increase of no more than 4.5% when measured according to Taber abrasion testing based on ASTM D1044 and a difference in water vapor transmission rate when compared to said polymeric substrate alone of no more than 5 grams/m2/day.

Abstract: A transparent exterior window film composite comprising a base sheet material having an outer PET (polyethylene terephthalate) film layer which has been surface treated to elevate adhesion thereto and which is impregnated with an ultra violet light absorber (UVA), the treated surface being coated with a UV stabilized acrylic polymer or co-polymer undercoat having a UV stabilized hard coat layer thereon formed from at least one aliphatic urethane acrylate oligomer and at least one multifunctional acrylate monomer, the undercoat layer having a thickness which is at least as thick as the hard coat.

Abstract: A low emissivity and EMI shielding transparent composite film typically for use in association with window glazing and comprising a transparent film substrate having on one side thereof an underlayer of abrasion resistant hardcoat material with at least one infrared reflective layer covering the underlayer, typically a metallic layer which may be encased in metal oxide layers, which is then covered with a thin external protective top coat of a cured fluorinated resin.

Abstract: A modified silicone release coating suitable for use with clear, polymer films that shows reduced adherence when the resultant liner is wound up into large rolls and the smooth soft surfaces are placed into contact with each other. The adherence is reduced by providing a release layer which has a sub micro-rough top surface produced through the inclusion of a relatively small number of relatively large particles.

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.
