  • Surface roughening of polymer films
    Patent number: 10836150
    Abstract: The surface roughness of a polymer film laminated to a metal substrate can be improved through the use of sufficient heating after application of a wax layer to the polymer film. In some cases, a thin liquid film or layer of a waterborne wax dispersion can be applied to the surface of a metal substrate laminated with a polymer film. After heating the polymer film and wax layer to a point at which the polymer film and wax layer begin to become molten, the surface roughness of the polymer film can become improved due to the presence of the wax.
    Type: Grant
    Filed: March 29, 2018
    Date of Patent: November 17, 2020
    Assignee: NOVELIS INC.
