  • Coated wallboard employing unbleached face paper comprising a coating containing soy protein
    Patent number: 5945198
    Abstract: A coating for providing a cover sheet used in the manufacture of wallboard with a light colored finish without the use of manila top plies is disclosed. The coating has a porosity adapted to allow evaporation of moisture from the wallboard core through the cover sheet, and maintain a desired smooth appearance. A high pigment-to-binder ratio is used to provide porosity, with soy protein being added to further enhance the porosity of the coating. The coating may be applied through various conventional methods of coating paper such as roll, spray, curtain, rod and vacuum.
