3M™ Polyurethane Protective Tape 8663/8663DL (dual liner) is made from an exceptionally tough abrasion resistant polyurethane elastomer that resists punctures, tearing, abrasion and erosion. It is formulated for resistance to ultraviolet light. 3M 8663 Tape provides a simple, easy method of protecting a surface from corrosion, abrasion and minor impact damage. 3M 8663 Tape and 3M 8663DL Tape are constructed with a long-aging, solvent-resistant, pressure-sensitive acrylic adhesive that is protected with an easy-release plastic liner. 3M 8663 Tape is a transparent tape available in three liner configurations: • Single polypropylene liner on the adhesive side. • Single skip-slit polypropylene liner on the adhesive side. • Dual liners, one on each side of the tape.
