Datasheets(X)
The pressure lock tape is made of black polypropylene with a modified acrylic adhesive on the back and is suitable for a wide range of indoor and outdoor applications, such as for doors, flexible solar cell panels, skylights, access panels, signage, display components and much more.
Suitable for bonding to metal (aluminium, stainless steel), glass, plastics with high surface energy (acrylic, polycarbonate, ABS) and painted surfaces. Unlike conventional fastening systems, such as screws or rivets, no holes that impair the optical appearance of the surface are required. The acrylic adhesive with high temperature resistance is suitable for different surfaces, e.g. high- and low-energy plastics, metals and powder coatings.
