Foam Tapes

Pres-On P8400 Series Vinyl Neoprene Foam Tapes offer a uniform, closed cell structure that resist the absorption of water, chemicals and other fluids. These tapes also provide good load bearing qualities, and help maintain a permanent, positive seal with the ability to fill larger gaps to seal out water and air. Fire-rated (UL, FM).

Application Notes

Thoroughly clean contact surface before use. Once tape has been applied, it cannot be removed and reused. Therefore, position tape carefully, assuring that it is in contact with all surfaces. If tape is misaligned, remove used unit, discard and repeat application with new unit. Test product for system compatibility as individual application conditions can impact results.
