3M™ Polyurethane Protective Tape 8658DL (dual liner) is a transparent, flame-retardant tape made from an
exceptionally tough polyurethane elastomer that resists puncture, tearing, and abrasion. This product is uniquely
formulated to pass the burn resistance requirements of FAR 25.853 when tested as a free standing tape. Applied as a
seam sealing tape to aircraft floor panels, this product establishes an excellent barrier to fluids and helps prevent
liquids from causing corrosion of the floor system. 3M 8658DL Tape incorporates a specially formulated, pressure
sensitive adhesive for fast and easy application, and can be applied over 3M uncured polysulfide sealant, such as AC770. This product is supplied in a dual liner configuration consisting of a polyethylene adhesive liner and a polyester
top liner used as an aid for application. These liners are removed after installation.
