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.
