Approximately 4 by 4 Inch, UltraTNT PSA Repair PatchUltraTNT™ PSA Tape is constructed with two layers of 0.25mil polyester film with light grey Ultra™ yarn inserted in the warp and bias. The backing is Pressure Sensitive, high tack, non-yellowing Adhesive.
UltraTNT™ PSA Tape has an excellent bond to the film side of Ultra™ and EPLX™ fabrics. Challenge recommends this process to create the best bond:
- Work in a room temperature of at least 70° F.
- Fabric should be clean and dry; if not, clean fabric surface with rubbing alcohol.
- Peel back release paper and apply tape evenly over tear or hole, a few inches at a time. If repairing a hole, you may want to apply a patch on both sides.
- Go back over the tape, applying even pressure with rubber seam roller (or by hand, if no roller available).
- Let cure for 24 hours for best adhesion.
