High-performance 3M double-coated industrial adhesive tape with acrylic and silicone adhesives, 48 in x 36 yd roll, ideal for silicone bonding and gasket assembly applications.
3M™ Double Coated Tape 9731-050 is a high-performance industrial adhesive tape specifically engineered for demanding bonding applications involving silicone materials. This specialized tape features a unique dual-adhesive construction with a high-performance acrylic adhesive on the face side and a silicone adhesive on the liner side, bonded to a 1 mil clear polyester film carrier. The 48-inch width and 36-yard length roll provides substantial coverage for large-scale manufacturing and assembly operations. This tape is ideal for attaching silicone rubber elastomers and foam substrates, making it essential for gasket assembly, sealing applications, and specialized industrial bonding tasks. The transparent polyester backing ensures clean, professional results without visible adhesive residue on finished products.
Developed for military, government, and advanced manufacturing applications, this tape delivers exceptional temperature and chemical resistance through its proprietary Adhesive 350 formulation on the face side. The combination of acrylic and silicone adhesives creates a versatile bonding solution that works across multiple substrate types while maintaining superior holding power in extreme environments. With a maximum operating temperature of 250°F (121°C) and minimum operating temperature of -40°F (-40°C), this tape maintains its adhesive properties across a wide thermal range. The 18-month shelf life ensures reliable performance throughout extended storage periods, while the primary liner of 58# polycoated kraft paper protects the adhesive during handling and storage.
This industrial-grade tape is available in a single roll per case configuration, making it suitable for high-volume production environments and original equipment manufacturers. The 2 mil total tape thickness without liner provides optimal balance between conformability and structural strength. 3M's rigorous quality standards ensure consistent performance across every roll, meeting the demanding requirements of aerospace, automotive, electronics, and specialty manufacturing industries. For industrial and occupational use only, this product is not intended for consumer applications and must be used in compliance with applicable health and safety regulations.
