Abstract: Systems and methods are described herein for manufacturing and using roofing membranes that are faster and easier to install than conventional adhesive-only membrane materials. In some embodiments, membrane materials are surface treated using a plasma flow, e.g., a blown-arc plasma flow, atmospheric plasma, corona plasma, or from portable plasma units, generated by passing a compressed plasma-generating gas through an electrical current to form the plasma-treated roofing membrane. The plasma treatments described herein may be applied as part of the manufacturing process, or in-situ at the site of roof installation. In some embodiments, membrane materials have surface chemistries, roughnesses and other surface characteristics that yield desired adhesion properties.

Abstract: A film structure with protection against manipulation includes a top film, a laser-inscribable layer which is arranged on the bottom side of the top film, and also a bottom film and a connecting layer for connecting the bottom film to the top film and the laser-inscribable layer. The connecting layer is arranged between the laser-inscribable layer and the bottom film. The film structure has an inscribed region and an uninscribed region. The top film is fused with the bottom film in the inscribed region of the film structure. As a result, it is virtually impossible to separate the top film with the inscribed layer from the bottom film without destruction in the event of a manipulation attempt.

Abstract: Dual-sided adhesive articles include a first crosslinked pressure sensitive adhesive layer with a first major surface and a second major surface, a second siloxane-based pressure sensitive adhesive layer with a first major surface and a second major surface, such that the first major surface of the second siloxane-based pressure sensitive adhesive layer is in contact with the second major surface of the first crosslinked pressure sensitive adhesive layer. The articles also include a release liner having a microstructured surface with an array of microstructures, where the microstructured surface is in contact with the second major surface of the second siloxane-based pressure sensitive adhesive layer. The microstructures of the microstructured surface of the second siloxane-based pressure sensitive adhesive layer are unstable when not in contact with the microstructured release liner, and disappear over time when in contact with a substrate.
