Premium black polyethylene preservation sealing tape with rubber adhesive for long-term outdoor storage and equipment protection. Offers excellent weatherability, stain resistance, and clean removal after up to two years of weather exposure. Ideal for industrial, military, and marine applications.
3M™ Preservation Sealing Tape 481 is a premium black polyethylene tape engineered with a unique rubber adhesive formulation designed for long-term preservation and sealing applications. This industrial-grade preservation tape delivers exceptional weatherability and stain resistance, making it ideal for protecting equipment and vehicles during extended outdoor storage periods of at least two years. The tape features excellent conformability to irregular surfaces and contours, thanks to its flexible polyethylene backing, while maintaining superior adhesion strength and clean removal properties even after prolonged weather exposure.
This versatile sealing tape is specifically engineered for demanding industrial and military applications where reliable protection and easy removal are critical. The rubber adhesive provides excellent adhesion to a wide selection of materials including metals, composites, and coated surfaces, while resisting common lubricants and strippable coatings. With a service temperature range from -7°C to 77°C (20°F to 170°F), the tape maintains consistent performance across diverse climate conditions. The black backing seamlessly blends with protective film coverings for a professional appearance, and the tape can be certified to Military Specification SAE AMS-T-22085 for aerospace and defense applications.
The 3-inch wide format provides efficient coverage for sealing, patching, and splicing operations in construction, transportation, and marine industries. Each case contains 12 rolls of 36-yard length tape, offering substantial coverage for comprehensive preservation projects. The pressure-sensitive rubber adhesive requires minimal effort to remove, reducing labor costs and surface damage during decommissioning. This tape is formulated for industrial and occupational use only, meeting stringent performance standards for professional applications.
