Premium industrial double-coated tape with acrylic and silicone adhesives for specialized silicone material bonding, gasketing, and high-temperature applications with exceptional chemical resistance.
3M™ Double Coated Tape 9731 is a premium industrial-grade adhesive tape engineered for demanding applications requiring bonding of silicone materials to various substrates. This innovative tape combines a high-performance acrylic adhesive (3M™ Adhesive 350) on the face side with a specialized silicone adhesive on the liner side, creating a versatile solution for complex assembly and gasketing applications. The tape features a clear 1 mil polyester film (PET) carrier that provides excellent dimensional stability, superior handling characteristics, and ease of die-cutting and lamination.
The unique differential adhesive design makes this tape ideal for specialized applications including silicone gasketing, keypad attachment, and printer toner cartridge refurbishing. The 3M™ Adhesive 350 on the face side delivers exceptional temperature and chemical resistance, while the silicone adhesive on the back side bonds exceptionally well to silicone substrates and rubber materials. With a total thickness of 5.5 mil and dimensions of 12 inches wide by 108 yards long, this single-roll case product is perfect for industrial converters and manufacturers seeking reliable, high-performance bonding solutions.
The double-lined construction features both a 58# polycoated kraft paper (PCK) liner (4.2 mil) and a polyester film liner (2.9 mil), providing reliable performance for die-cutting, automated dispensing, and manual application methods. The tape maintains excellent performance across a wide temperature range from -40°C to 121°C (-40°F to 250°F), making it suitable for both indoor and outdoor industrial applications. This professional-grade tape is specifically designed for industrial and occupational use only, meeting the stringent requirements of aerospace, automotive, electronics, medical device, and general industrial manufacturing sectors.
