Professional-grade double coated tape with dual adhesive system for bonding silicone materials, featuring acrylic and silicone adhesives with exceptional temperature and chemical resistance for industrial applications.
3M™ Double Coated Tape 9731 is a high-performance industrial adhesive tape specifically engineered for bonding silicone rubber elastomers, foams, and specialized gasketing applications. This professional-grade tape features a unique dual-adhesive system with 3M™ Adhesive 350 (acrylic-based) on the face side and silicone adhesive on the liner side, mounted on a 1 mil clear polyester film (PET) carrier. The combination of these specialized adhesives provides exceptional temperature and chemical resistance, making it ideal for demanding industrial applications where silicone materials must be securely bonded to various substrates.
The tape measures 2 inches in width and 36 yards in length with a total thickness of 5.5 mil, and comes in a convenient 24-roll case for industrial use. It features a double-lined construction with a 58# polycoated kraft paper (PCK) primary liner (4.2 mil) and a 3 mil polyester film secondary liner, both of which help reduce edge curl and protect the tape from humidity extremes. The thin polyester carrier provides excellent dimensional stability, improved handling characteristics, and ease of die-cutting and lamination for automated dispensing systems.
This industrial tape is specifically designed for applications including air and liquid filters, fluid handling equipment, heat exchangers, silicone keypad attachment, and printer toner cartridge refurbishing. It operates effectively across a wide temperature range from -40°F to 250°F (-40°C to 121°C) and demonstrates very good holding power, excellent UV resistance, and strong solvent resistance. The silicone adhesive on the back side provides superior bonding to silicone rubber and various silicone surfaces, while the acrylic adhesive on the face side ensures high adhesion to a wide variety of materials, making this tape an excellent choice for gasketing and other specialized bonding applications in aerospace, automotive, electronics, and general industrial markets.
