Erosion Protection
3M™ Polyurethane Protective Tape 8663DL is a transparent 18 mil, polyurethane elastomer tape designed to protect leading edges such as vertical stabilizers against rain and sand. Our tough polyurethane backing is scratch, tear, erosion, puncture and impact resistant. The transparent tape can be painted or applied over painted surfaces. This tape has excellent environmental resistance properties and has been used to isolate and protect substrates from environmental damage and erosive elements. The bottom 3 mil polyethylene liner protects the adhesive from contamination prior to application. The top liner is imprinted with black lines at four inch intervals aids in precise installation. 3M™ Polyurethane Protective Tape 8663DL is qualified to leading aircraft manufacturer specifications for protection from sand and rain erosion.

Adhere with Acrylic
This tape features a pressure sensitive acrylic adhesive that adheres effectively to a variety of substrates. Once bonded this adhesive will provide high, secure adhesion for extended periods. This acrylic adhesive maintains its bond strength through a range of climate and temperature changes. When needed, this tape removes easily.
