921XL
***Discontinued*** Adhesive Transfer Tape
Discontinued A 1.0 mil. transfer tape with A-70 acrylic adhesive primarily used for mounting and joining applications. A-70 is a soft pressure-sensitive acrylic adhesive system. If also features low initial adhesion to paper and many other materials with minimal bond build up. 921XL also consists of an extended liner (XL), that extends beyond the width of the adhesive to provide easy liner starting and removal. The liner extension provides a dry edge on each side of the tape for easy removal, however, this decreases the adhesive coating by 1/8in. overall. The liner is printed with the message, "Remove to Expose Adhesive".
