Aerospace-grade polyurethane protective tape offering 60x protection of paint with UV stability and erosion resistance for aircraft composite parts
3M™ Polyurethane Protective Tape 8734NA is an aerospace-grade protective film engineered specifically for composite aircraft parts. This revolutionary erosion-resistant tape provides a permanent, durable barrier against impact, erosion, sand, dust, and rain damage. The co-curable film is designed to be integrated into composite structures during manufacturing via autoclave or vacuum bag processing, creating a tough, protective surface that dramatically reduces maintenance costs and aircraft downtime.
This innovative surface protection solution offers 60 times the protection of conventional paint, making it an ideal choice for aircraft requiring superior performance in harsh environmental conditions. The UV-stable polyurethane film is conformable to most surfaces and can be layered or stacked to provide extra protection where needed. With a 6 mil thickness and maximum operating temperature of 250°F (121°C), this tape maintains its protective qualities across the full performance envelope of modern aircraft. The tape is resistant to abrasion, erosion, scratches, punctures, and impact, while remaining easily repairable with 3M™ Scotch-Weld™ Repair Paste 2110.
The 8734NA tape measures 24 inches wide by 36 yards long and comes in one roll per case. It is uniquely formulated for use with 3M structural adhesive films and offers resistance to most aviation fluids. This aerospace solution combines performance and convenience, enabling composites to be used in applications subjected to adverse environmental conditions while reducing overall composite assembly and repair costs.
