UltraTNT PSA Tape is a waterproof seam repair tape with Ultra™ fiber. Constructed with two layers 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 Polyester film

- Light grey Ultra yarn inserted in the warp and bias

- Pressure Sensitive adhesive backing

Note - This seam seal tape will work with all of our tapeable fabrics ( X series X-pac, ECOPAK EPLX, Challenge Ultra, Dyneema Composite Fabric, Venom, etc).

Sold in 1 yd sections. Please note that all sections are pre-cut and cannot be sent continuous. For example, buying a qty of "2" will result in two separate 1 yd sections. If you need longer pieces, it's perfectly fine to join multiple 1 yd sections together when taping your seams.
