Alla scoperta dei sistemi di fissaggio richiudibili

Adhesives make countless tasks much easier. Imagine how convenient it is to have a roll of duct tape on hand for quick fixes, or how useful it is to protect surfaces from paint using masking tapes. When looking at industrial processes, adhesives often prove more efficient than rivets, screws, or welding. High-performance double-sided tapes and structural adhesives can revolutionize many procedures, making them simpler, faster, safer, and cleaner, while delivering better aesthetic results. It’s worth noting that the range of adhesive solutions is so vast that it's hard to know them all—many people, for example, aren't 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 buttons, screws, bolts, or removable rivets. But there's a much more convenient option that often replaces traditional methods effectively: reusable adhesive fastening systems. These are special adhesive tapes that have a backing with adhesive on one side to stick securely to a chosen surface, and on the other side, they feature hooks that can latch onto the hooks of another similar tape, ensuring a secure closure. This type of system is commonly referred to as hook and loop fasteners. They usually have mushroom-shaped heads that provide a strong grip while allowing for easy opening, without the need for drilling, additional tools, or compromising the overall design.

In What Situations Can You Use Hook and Loop Fastening Tapes?

The applications for hook and loop adhesive tapes are incredibly diverse, thanks to the fact that leading manufacturers offer tapes designed for different materials—such as metal, glass, plastic, and more. A typical example is in the transportation industry, where these fasteners replace screws used to mount panels on ceilings and walls. Applying and removing panels becomes much easier, making maintenance more straightforward. They are also highly practical for setting up and taking down trade show displays, or for securing commercial signs. 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, especially when it comes to reusable fastening systems. What sets apart the various hook and loop tapes from this American brand? The differences start with the material they're intended for—some are designed for translucent surfaces, others for metals and plastics, while some are suitable for flexible substrates or powder-coated surfaces. The holding power and thickness also vary; some tapes are very thin, measuring just 2.5 millimeters when closed, while others can be up to 6 millimeters thick. Some are meant for indoor use only, while others perform well outdoors. Additionally, the number of times you can open and close the system varies, with some capable of over 1,000 or even 5,000 cycles.

For example, the 3Mâ„¢ Dual Lockâ„¢ SJ3560 is designed for metal, glass, plastic, and powder-coated surfaces, and can withstand up to 1,000 openings and closings with a total thickness of 5.7 millimeters. Each square centimeter of this tape contains 40 hooks, ensuring a strong and reliable grip.
