Publication number: 20210147648Abstract: Articles and intermediates are described comprising an organic polymeric base member and a hardcoat layer disposed on the organic polymeric base member, wherein the hardcoat layer can be stretched 25-75% without cracking. A siliceous layer is disposed on the hardcoat layer. The siliceous layer has a porosity of no greater than 10% and a thickness no greater than 1 micron. In some embodiments, the article further comprises a surface layer comprising a zwitterionic compound bonded to the siliceous layer.Type: ApplicationFiled: August 14, 2019Publication date: May 20, 2021Inventors: Richard J.

Publication number: 20210114361Abstract: Various embodiments disclosed relate to a surfacing film. The surfacing film includes a base layer. The base layer includes a thermoplastic polyurethane film comprising a reaction product of a reaction mixture of a diisocyanate, a polyester polyol having a melting temperature of at least about 30° C.; and a diol chain extender. There are many reasons to use the surfacing film including easier and more cost effective manufacturing of the surfacing film by directly extruding the base layer by mixing the reaction mixture in an extruder. Another reason to use the surfacing film is that the film has improved resistance to discoloration. Another reason to use the film is that the film shows good toughness.Type: ApplicationFiled: August 6, 2019Publication date: April 22, 2021Inventors: Charlie Chia-Tie HO, Yongshang LU, John J. JAROS, Jay M. JENNEN, Ryan M. BRAUN, Sean P. ADDISON, Trevor A. LARSON, Richard J. POKORNY, Joan M. NOYOLA, Zachary J. MALMBERG, Thomas P. KLUN, Moses M. DAVID, Jun MA, Cordell M. HARDY
