High-performance double coated tape with acrylic and silicone adhesives for specialized silicone bonding applications, offering exceptional temperature and chemical resistance.
3M™ Double Coated Tape 9731 is a high-performance adhesive tape specifically engineered for demanding applications involving silicone materials and specialized bonding requirements. This innovative tape features a unique combination of acrylic adhesive on the face side and silicone adhesive on the liner side, mounted on a 1 mil clear polyester film (PET) carrier. The tape is ideal for attaching silicone rubber elastomers, foam, and other specialized applications such as silicone gasketing, where exceptional temperature and chemical resistance are critical.
The tape's dual-adhesive system provides exceptional versatility for industrial applications. The face side features 3M™ Adhesive 350, a high-performance acrylic adhesive that delivers exceptional temperature and chemical resistance, while the back side features a 3 mil silicone adhesive that bonds exceptionally well to silicone substrates. This differential adhesive design makes it perfect for applications including silicone keypad attachment and printer toner cartridge refurbishing. The double-linered construction includes a 58# polycoated kraft paper (PCK) liner on one side and a 3 mil polyester film (PET) liner on the other, providing reliable performance for industrial applications such as die-cutting and automated dispensers.
With dimensions of 2 inches wide by 108 yards long and a total thickness of 5.5 mil, each case contains 6 rolls for convenient bulk purchasing. The tape operates effectively across a temperature range of -40°C to 121°C (-40°F to 250°F) and provides excellent UV resistance, very good holding power, and good solvent resistance. Ideal for gasketing, filters, silicone foams, and rubber applications, this industrial-grade tape can be pre-applied to gasketing material and die-cut for precision parts, offering instant adhesion for quick and efficient assembly processes.
