2273 specifications

3M 2273 is a high-performance double-sided tape that is engineered for a variety of demanding applications in both industrial and household settings. This tape is particularly well-regarded for its versatility and strong bonding capabilities, making it a popular choice among professionals and DIY enthusiasts alike.

One of the standout features of 3M 2273 is its robust adhesive technology. It utilizes a proprietary acrylic adhesive that provides excellent bonding strength on a wide range of surfaces, including metals, plastics, glass, and painted materials. This versatility allows users to apply the tape in different scenarios, whether it’s for mounting, joining, or attaching parts. The ability to adhere to challenging substrates without the need for additional primers or surface treatment simplifies the application process.

The tape is designed with a unique combination of a thick carrier film and a high-quality adhesive layer, which contributes to its durability and reliability. The thick backing provides excellent conformability, allowing the tape to maintain its adhesion even on irregular or textured surfaces. This feature is particularly valuable in automotive, aerospace, and construction industries, where the integrity of bonds is crucial.

Another key characteristic of 3M 2273 is its temperature resistance. This tape can perform effectively in a wide temperature range, making it suitable for applications exposed to heat or cold environments. Whether it’s used in manufacturing processes or for outdoor projects, the tape maintains its bonding properties, ensuring long-lasting performance.

The transparency of 3M 2273 adds to its appeal, particularly for applications where aesthetics are important. The discreet appearance allows for clean finishes, making it ideal for use in electronic devices, graphics, and signage where visible seams could compromise visual appeal.

Furthermore, 3M 2273 is easy to manipulate, allowing for quick and efficient application. The tape is available in various widths and lengths, catering to the diverse needs of users. It also boasts excellent shear strength, which helps it resist slippage and provides a secure hold over time.

In summary, 3M 2273 stands out in the realm of double-sided tapes due to its exceptional bonding capabilities, temperature resistance, and versatility across a variety of substrates. Its reliable performance and user-friendly design make it an essential tool in both industrial settings and everyday applications, ensuring that it meets the rigorous demands of users worldwide.
