Premium industrial double coated tape with acrylic adhesive, polyester carrier, and exceptional temperature resistance from -12°C to 219°C for high-performance bonding applications.
3M™ Double Coated Tape 9740 is a premium industrial bonding solution that delivers excellent continuous performance across a broad temperature range from -12°C to 219°C. This high-performance tape features an acrylic adhesive that bonds exceptionally well to most substrates, including low surface energy plastics, metals, and foam materials. The thin polyester film carrier provides superior dimensional stability and improved handling during die-cutting and slitting operations, making it ideal for automated dispensing and laminating applications.
Designed for demanding industrial applications, this tape combines high initial adhesion with excellent shear holding power, making it a razor-thin alternative to traditional fastening methods like glue, screws, and rivets. The robust 55 lb. densified kraft paper liner protects against humidity while enabling superior conformability to both irregular and flat surfaces. With its exceptional peel, tack, and shear properties, this tape is specifically engineered for high-temperature splicing applications in corrugators and other industrial settings where heat resistance and durability are critical.
The 3M Double Coated Tape 9740 is ideal for attachment to irregular surfaces, bonding decorative trim, high-speed flying splices, and applications requiring adhesion to low surface energy substrates. Its acrylic adhesive formulation ensures superior bonding performance while maintaining excellent temperature resistance, making it the preferred choice for manufacturers seeking reliable, efficient bonding solutions that reduce production time and improve product quality.
