  • Publication number: 20230020860
    Abstract: An air and water barrier article comprised of multiple layers. The layers include a porous layer, a polymeric layer disposed on a front side of the porous layer, and a pressure sensitive adhesive disposed on a second side of the porous layer. In certain embodiments, a top polymeric layer having hydrophobic and UV resistant properties will be provided on a surface of the first polymeric layer opposite the adhesive layer. Each of the polymeric layers and the porous layer can be formed of a material(s) having a Tg between ?40° C. and 20° C. The top layer, if present, can have a Tg between ?5 and 30° C. The barrier article can provide nail seal ability and have a weight of less than 30 ounces per square yard.

  • Publication number: 20220403218
    Abstract: An acrylic adhesive formulation that can be used for various building envelope applications. The adhesive can be coated onto various substrates such as flashing, vapor permeable membranes, vapor impermeable membranes and roofing underlayment's to make them self-adhering. The adhesive can be applied in cold temperatures from 0 degrees Fahrenheit (?18 degrees Celsius) but will maintain integrity at high temperatures without sacrificing the bonding to common construction/fenestration surfaces. The adhesive can include a blend of a plasticizer and an ultra-violet (UV) curable acrylic base polymer, which can be crosslinked upon exposure to a narrow wavelength range of ultra-violet light.

  • Publication number: 20210130652
    Abstract: According to one embodiment, a process for applying an adhesive material onto a barrier sheet substrate is provided. The process includes providing an adhesive material having viscosity of at least about 10,000 centipoise at 250° F. The adhesive material is applied to a multitude of cavities on a surface of a first tool with a coater unit in close proximity to the surface. The adhesive material is transferred from the surface of the first tool to the substrate supported on a surface of a second tool and pressed against the surface of the first tool.
