3M 8671 Polyurethane Tape
3M 8671 Polyurethane Tape is a 14 mil, UV-resistant polyurethane protective film engineered for aerospace leading edge erosion protection in indoor and outdoor environments.
3M 8671 Polyurethane Tape is designed for aerospace applications requiring a balance of erosion resistance, conformability, and controlled weight. Its abrasion-resistant polyurethane elastomer film protects aircraft surfaces from rain, sand, and impact damage.
The tape uses a long-aging, solvent-resistant, pressure-sensitive acrylic adhesive that provides reliable bonding to aluminum, composite structures, primers, and painted finishes commonly found in aerospace manufacturing and maintenance.
With a total thickness of 0.014 inch, 3M 8671 delivers durable protection for leading edges, propellers, rotor blades, and stabilizers. The UV-stable formulation supports both indoor and outdoor service where environmental exposure is expected.
