High-performance double coated tape with acrylic and silicone adhesives for silicone material bonding, gasketing, and industrial applications with exceptional temperature resistance and chemical stability.
3M™ Double Coated Tape 9731 is a high-performance industrial adhesive tape specifically engineered for demanding applications requiring silicone material bonding. This specialized tape features a unique combination of acrylic and silicone adhesives on a thin 1 mil clear polyester film carrier, making it ideal for applications where silicone elastomers and foam must be securely attached to various substrates. The tape delivers exceptional temperature and chemical resistance, with operating temperatures ranging from -40°F to 250°F, ensuring reliable performance in extreme conditions.
The tape's dual adhesive system includes 3M™ Adhesive 350 on the face side, providing superior adhesion to a wide range of materials, and a specialized silicone adhesive on the liner side that bonds exceptionally well to silicone substrates. This differential adhesive configuration makes it perfect for gasketing applications, silicone keypad attachment, and printer toner cartridge refurbishing. The double-linered design features a 58# polycoated kraft paper primary liner and a 3 mil PET secondary liner, both providing reliable performance for industrial applications including die-cutting and automated dispensers.
With its 24-inch width and 108-yard length on a 6-inch core, this roll offers substantial coverage for production environments. The thin polyester carrier provides excellent dimensional stability and improved handling characteristics, with ease of die-cutting and lamination. The tape's formulation delivers very good holding power, excellent UV resistance, and superior solvent resistance, making it an essential solution for aerospace, automotive, electronics, medical device manufacturing, and general industrial applications requiring premium adhesive performance.
