3M™ Polyurethane Protective Tape 8663 is an erosion protection tape and primarily used on aircraft leading edges such as vertical stabilizers. It is constructed of a polyurethane backing coated with a long-aging, solvent-resistant, pressure sensitive adhesive that is protected with a transparent easy-release liner.


Erosion Protection
3M™ Polyurethane Protective Tape 8663 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. A polyethylene liner helps protect the adhesive from contamination prior to bonding. 3M™ Polyurethane Protective Tape 8663 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.
