Abstract
A laminate tape that has a bottom layer of aggressive adhesive formulated to have sufficient adhesion to construction materials to as low as 20 degrees F. The adhesive is applied in a layer of about 2 to 5 mils. A second layer that is about 10 to 60 mils thick is made of rubberized asphalt, which provides self-sealing capabilities. In one embodiment, the first layer has strips of adhesive and sections of rubberized asphalt. The third layer is a film, which can be a thin, contiguous polymer, fabric or particulate. The laminate can be used where a strong adhesive is needed that will adhere to construction materials at or near 20 degrees Fahrenheit, while still retaining self-sealing characteristics.
