Premium dual-adhesive industrial tape for silicone bonding with acrylic and silicone adhesives, ideal for gasketing, filters, and foam applications with exceptional temperature and chemical resistance.
3M™ Double Coated Tape 9731 is a premium industrial adhesive tape specifically engineered for demanding applications requiring bonding of silicone materials to various substrates. This tape features a unique dual-adhesive system with high-performance acrylic adhesive (3M™ Adhesive 350) on the face side and silicone adhesive on the liner side, making it ideal for specialized applications such as silicone gasketing, keypad attachment, and printer toner cartridge refurbishing. The tape is constructed with a 1 mil clear polyester film (PET) carrier that provides exceptional dimensional stability and ease of die-cutting and lamination.
Designed for industrial and occupational use, this double coated tape combines silicone-based and rubber-based adhesives on a flexible, strong polyester carrier to deliver excellent performance across a wide range of applications. The 3M™ Adhesive 350 on the face side provides very high adhesion to a wide variety of materials, while the silicone adhesive on the back side bonds exceptionally well to silicone rubber and elastomers. The tape operates effectively across temperature ranges from -40°F to 250°F (-40°C to 121°C), offering superior temperature and chemical resistance suitable for aerospace, automotive, electronics, and general industrial applications.
The double-linered construction features a 58# polycoated kraft paper (PCK) liner (4.2 mil) on the primary side and a 3 mil polyester film (PET) liner on the secondary side, both providing reliable performance for industrial applications including die-cutting and automated dispensers. This configuration helps reduce edge curl and protects the tape from humidity extremes. With 72 rolls per case, each roll measuring 1/2 inch wide by 36 yards long at 5.5 mil total thickness, this product is ideal for gasketing, filters, and silicone foam and rubber applications where instant adhesion and quick application are essential.
