Premium black polyethylene preservation tape with rubber adhesive for long-term equipment protection. Resists weathering, stains, and maintains integrity for 2+ years. Military-spec certified, 72 rolls per case.
3M™ Preservation Sealing Tape 481 is a premium black polyethylene tape engineered for long-term equipment and vehicle preservation. This industrial-grade sealing tape features a unique rubber adhesive formulation that provides exceptional weatherability and stain resistance, making it ideal for outdoor applications in both hot and cold weather conditions. The tape maintains its protective properties for at least two years of continuous outdoor exposure while still allowing quick and clean removal when your preservation project is complete.
Designed for demanding industrial and military applications, this preservation tape excels in protecting equipment during extended storage and transportation. The polyethylene backing conforms easily to irregular surfaces and contours, ensuring complete seal coverage on complex geometries. With a service temperature range of -7°C to 77°C (20°F to 170°F), this tape performs reliably across diverse climate conditions. The black polyethylene backing not only provides excellent durability but also blends seamlessly with black film coverings for a professional appearance. This product can be certified to Military Specification SAE AMS-T-22085, meeting the stringent requirements of military and government applications.
Each case contains 72 rolls, making it economical for large-scale industrial operations. The tape's superior adhesion strength of 25 oz/in combined with its 500% elongation at break ensures secure bonding and flexibility on curved surfaces. Whether you're preserving marine equipment, aerospace components, or general industrial machinery, 3M Preservation Sealing Tape 481 delivers dependable performance and professional results. The rubber adhesive requires significantly less effort to remove compared to competing products, even after extended weather exposure, reducing labor costs and equipment damage during decommissioning.
