UltraTNT PSA Tape is a waterproof seam repair tape with Ultra™ fiber. Constructed with two laters of 0.25 mil polyester film with light grey Ultra yarn inserted in the warp and bias. The backing is a pressure sensitive, high-tack, non-yellowing adhesive. Designed to be applied to the film side of fabrics to reinforce and waterproof seams. The tape is very stretch-resistant along the length of the roll, where there are straight parallel Ultra yarns inserted to control stretch. The Ultra CrossPly™ yarn helps control bias stretch and adds to the tear-resistance of the tape. Compared to stitching alone, using a quality seam sealing tape makes your finished product stronger (i.e. it lasts longer) and also more waterproof. For some laminated fabrics, it's a must-have to prevent issues like stitch elongation. Construction: - 2 layers of .25 mil
