  • Patent number: 11254104
    Abstract: A multilayer fluoropolymer film comprising, in order: a first layer comprising a first polymer, the first polymer comprising at least 35 mol percent tetrafluoroethylene comonomer, at least 15 mole percent vinylidene fluoride comonomer, and at least 5 mol percent hexafluoropropylene comonomer, based on the total mol percent of the first polymer; a second layer comprising a second polymer, the second polymer comprising at least 50 mol percent vinylidene fluoride comonomer, based on the total mol percent of the second polymer; and a third layer comprising a third polymer, the third polymer comprising at least 50 mol percent methylmethacrylate comonomer, based on the total mol percent of the third polymer. The multilayer fluoroplymer films are useful for example, in multi-layer film applications (e.g., traffic sign protection, commercial graphic protection, paint protection, windows, windshields, building exteriors, and photo voltaics).

  • Publication number: 20200319384
    Abstract: The present disclosure generally relates to retroreflective sheeting including a topcoat and to methods of making such sheeting. In some embodiments, the retroreflective sheeting includes (1) a first major surface that is a structured surface having a structure imparted by a plurality of prismatic cube corner elements; (2) a second major surface opposite the first major surface, the second major surface being substantially planar and including a polycarbonate; and (3) a topcoat adjacent to at least a portion of the second major surface and the topcoat including a solvent-based composition.

  • Publication number: 20040213945
    Abstract: The present invention relates to articles comprising a substrate, a release liner and an adhesive layer sandwiched between the substrate and release liner and methods of manufacturing such articles. The release liner has a relatively high coefficient of friction and has shrinkage properties that are substantially the same as or greater than the substrate. The article exhibits good roll stability, being substantially free of defects when supplied in a roll form.
