Pressure Sensitive Adhesive for Robust Bond
3M™ Polyurethane Protective Tape 8658DL features an acrylic, pressure sensitive adhesive for a firm, lasting bond. We use acrylic, pressure sensitive adhesive for its ability to wet out the surface and its ability to form a strong bond to aircraft floor panels. Our tape is solvent resistant and adheres well to composite materials. The adhesive maintains its bond strength through a range of climate and temperature changes. Our dual liner features a 3 mil polyethylene protective liner over the adhesive and a top liner imprinted with black lines at four inch intervals to aid in precise installation.
