  • Volumetric effect glass fiber wallcoverings
    Patent number: 6974602
    Abstract: A glass fiber wall covering is made by sequential application of aqueous dispersion and an image coating to selectively create an image for painted effects. The image pattern is based on a spatial expansion of second image coating upon heating during the drying process.
    Type: Grant
    Filed: December 29, 2003
    Date of Patent: December 13, 2005
    Assignee: Johns Manville
    Inventor: Per Edlund
  • Strippable glass fiber wall covering
    Patent number: 6939818
    Abstract: An improved strippable glass fiber wall covering and process for its formation are provided. Initially, both sides of a glass fiber fabric are coated with a first coating applied from an aqueous dispersion of starch binder and polymeric latex binder. In a preferred embodiment a cross-linking agent and pigment also are present in the first aqueous dispersion. Following the drying of such dispersion to form a first coating on both surfaces, a second dried coating is provided on one side only that serves as a separation layer. The second coating is applied from an aqueous dispersion comprising paraffin and a rheology modifier. When applied to the wall in conventional manner, the separation layer facilitates the removal of the wall covering with ease when its time of usefulness is concluded.
