High-performance dual adhesive double-coated tape with acrylic and silicone adhesives for bonding silicone materials, gasketing, and specialized industrial applications with exceptional temperature and chemical resistance.
3M™ Double Coated Tape 9731 is a high-performance adhesive tape specifically engineered for demanding applications where silicone materials must be bonded to various substrates. This innovative tape features a unique combination of acrylic and silicone adhesives applied to both sides of a thin, clear polyester film (PET) carrier. The face side is coated with 3M™ Adhesive 350, a high-performance acrylic adhesive that provides exceptional temperature and chemical resistance, while the liner side features a specialized silicone adhesive that bonds exceptionally well to silicone substrates. This differential adhesive design makes it ideal for applications including gasketing, filters, silicone foams, rubber components, and specialized industrial bonding tasks.
The tape measures 12 inches in width and 36 yards in length with an overall thickness of 5.5 mil, providing excellent dimensional stability and ease of handling. It features a dual-liner system with a 58# polycoated kraft paper (PCK) primary liner and a 3 mil polyester film secondary liner, both of which help reduce edge curl and protect the tape from humidity extremes. The thin 1 mil clear polyester carrier provides superior dimensional stability while enabling easy die-cutting and lamination for automated dispensing systems. Operating temperature range extends from -40°C to 121°C (-40°F to 250°F), making it suitable for both indoor and outdoor applications across multiple industries.
This specialized double-coated tape is particularly valuable for pre-applying to gasketing materials for die-cutting, instant adhesion to keep manufacturing processes moving forward, and replacing gaskets or bonding and sealing simultaneously. The silicone adhesive on the back side is specifically designed for silicone keypad attachment and printer toner cartridge refurbishing, while the acrylic adhesive on the face side ensures very high adhesion to a wide variety of materials. With excellent UV resistance, strong holding power, and good solvent resistance, 3M™ Double Coated Tape 9731 delivers reliable performance for aerospace, automotive, electronics, medical devices, and general industrial applications.
