  • Publication number: 20070264471
    Abstract: There is provided a roofing membrane with factory applied non-tacky primer used as a primer in splicing adjacent panels of membrane together as well as roofing accessories and laminates using tape adhesive without the need to field prime the membrane. In addition, the primer is used to bond membrane that has been factory coated with a primer to substrates so only field adhesive applied on the substrate to receive membrane is required, without the need to field coat the membrane with adhesive.

  • Publication number: 20070137777
    Abstract: A method of forming a building material with a pre-applied adhesive may include providing a first and second membrane positioned in the same planar orientation and having a gap between them. The first membrane may include an adjacent edge, and the second membrane may include an adjacent edge. The adjacent edges may face each other. A first adhesive tape may be applied to a top planar surface of the first membrane and a second adhesive tape may be applied to the top planar surface of the second membrane. The first and second adhesive tapes extend into the gap.
