UltraTNT PSA Tape 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. 30mm wide and can be trimmed or patch-worked to suit. 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. UltraTNT™ PSA Tape has an excellent bond to the film side of Ultra™ and EPLX™ fabrics. We recommend this process to create the best bond: Work in a room temperature of at least 21° C. Fabric should be clean and dry; if not, clean fabric surface with Isopropyl alcohol and allow to dry. Peel back release paper and apply tape evenly over seam, a working say 5 – 10 centimeters at a time. Go back over the tape, applying even pressure with rubber seam roller (or firmly by hand, if no roller available). Let cure for 24 hours for best adhesion.
