  • Pass FMVSS302, CAN/CSA C22.2 #017-92, and UL 94 HF1 for flammability
  • Resist acids, alkali, ozone, and oxidation

P8100 Series Neoprene / EPDM / SBR Closed Cell Foam Tapes are general application tapes recommended for sealing roof curbs to A/C units, as well as sealing out rain, moisture, and dust. These watertight tapes also conform to irregular surfaces and are ideal for gasketing and weatherproofing windows and doors.

Application Notes

Ensure bonding surfaces are well unified, clean, dry and free of dirt and oils. Apply firm and even pressure to improve adhesive-to-surface contact. Allow proper temperature and time to enhance bond strength as adhesive flows onto the surface.

  • Release Liner: Brown Kraft Paper
  • Custom die-cut shapes
  • Also available with acrylic pressure sensitive adhesive on one-side (minimums may apply)
