3M 8672 Polyurethane Tape
3M 8672 Polyurethane Tape is a lightweight, 8 mil UV-resistant protective film designed for aerospace leading edge erosion protection and surface shielding.
3M 8672 Polyurethane Tape is engineered for applications where erosion protection is required without adding unnecessary weight. Its thin polyurethane elastomer film provides reliable resistance to rain, sand, and surface abrasion on exposed aircraft components.
The tape uses a pressure-sensitive acrylic adhesive that bonds effectively to aluminum, painted surfaces, and selected plastics. This construction supports stable adhesion in both indoor and outdoor aerospace environments.
With a total thickness of 0.008 inch, 3M 8672 is well suited for propellers, stabilizers, and other leading edges where conformability and weight control are critical. Transparent and glossy black color options support both visual inspection and aesthetic requirements.
Frequently Asked Questions
What makes 3M 8672 different from thicker leading edge tapes?
3M 8672 provides erosion protection in a thinner, lighter construction, making it suitable where weight and aerodynamic profile are priorities.
Is 3M 8672 suitable for outdoor aerospace exposure?
Yes. The tape is UV-resistant and designed to withstand rain and sand erosion in outdoor aerospace environments.
What color options are available?
3M 8672 is available in transparent and glossy black to support inspection needs or visual concealment.
