Alla scoperta dei sistemi di fissaggio richiudibili

Adhesives make countless tasks much easier. Think about how handy it is to have a roll of duct tape for quick fixes, or how convenient it is to protect surfaces from paint using masking tapes. In industrial settings, structural adhesives and high-performance double-sided tapes often prove more efficient than rivets, screws, or welding. In fact, adhesives—whether in the form of tapes or liquids—can revolutionize many processes, making them simpler, faster, safer, cleaner, and more aesthetically pleasing. It’s worth noting that the range of adhesive solutions is so vast that it's hard to know them all. For example, not many people are familiar with the features and benefits of the latest generation of reusable fastening systems.

What Are Reusable Fastening Systems?

Some fastenings are meant to last forever, and they are typically done with welding, structural adhesives, or rivets. Others, however, are designed to be temporary or allow for easy opening and closing without replacing the components involved. In such cases, you might use velcro buttons, screws, bolts, removable rivets, or similar methods. But there's a much more convenient solution that often outperforms traditional methods: adhesive reusable fastening systems. These are special adhesive tapes that have a backing with adhesive on one side to stick firmly to the chosen surface, while the other side has hook-like protrusions that can latch onto another tape of the same type, ensuring a secure yet removable connection. This system is commonly referred to as hook and loop. These tapes are usually covered with mushroom-shaped heads that provide a strong hold while allowing easy removal, without the need for drilling, additional tools, or damaging the overall design.

In What Situations Can You Use Hook and Loop Tapes?

The applications for hook and loop tapes are incredibly diverse, especially since leading manufacturers offer tapes specifically designed for different materials—such as metal, glass, plastic, and more. A typical example of their use is in the transportation industry, where these fasteners replace traditional screws used to attach panels to ceilings or walls. This makes installation and removal much easier, simplifying maintenance tasks. They’re also very practical for setting up and taking down trade show displays, securing commercial signs, or even organizing cables and tools. In all these cases, you get a secure but non-permanent fastening that requires no additional work beyond applying the two hook and loop tapes together.

Types of Reusable Fastening Systems

As is often the case with industrial adhesives, 3M is a key reference point, especially when it comes to reusable fastening systems. What sets apart the various 3M hook and loop tapes? The differences start with the material they're intended for—some are designed for transparent surfaces, others for metals and plastics, and some for flexible or powder-coated surfaces. The holding power and thickness also vary: some tapes are very thin, only occupying 2.5 mm when closed, while others are thicker, reaching around 6 mm. Some are suitable for indoor use, while others are durable enough for outdoor conditions. Additionally, the number of times the fastener can be opened and closed varies—some can handle over 1,000 or 5,000 cycles.

For instance, the 3Mâ„¢ Dual Lockâ„¢ SJ3560 system is ideal for fastening metal, glass, plastic, and powder-coated surfaces, and it can withstand up to 1,000 open-close cycles with a total thickness of 5.7 mm. Each square centimeter of this tape contains 40 hooks, ensuring a strong and reliable grip. Whether you're working on automotive parts, electronics, or construction projects, these advanced fastening systems offer a smart, versatile, and long-lasting alternative to traditional methods.
