Adhesive properties and mechanical performance

The 3M™ SJ3572 Hook Tape is based on a high-performance acrylic adhesive that ensures immediate and lasting adhesion to most smooth or slightly textured surfaces.

The back of the tape is equipped with polypropylene hooks designed to engage precisely with the loops of the counterpart. This system guarantees a repeatable opening and closing cycle without significant performance loss.

Resistance to tensile and shear stress

The SJ3572 offers high tensile strength, suitable for industrial applications subject to vibration or continuous mechanical stress.

Shear resistance is also optimized to hold horizontal or inclined assemblies without gradual sliding, even under prolonged static load.

Key mechanical characteristics:

• Tensile strength: firm hold, compatible with repeated loads
• Shear resistance: stable hold under static stress
• Opening/closing cycles: designed for repeated use in industrial settings
• Acrylic adhesive: bonds to metal, plastic, painted wood, and composite surfaces
• Service temperature: range compatible with standard industrial environments

Compared to the 3M™ SJ3541 range (finer hooks, light office use), the SJ3572 targets applications with higher mechanical demands, featuring a more robust hook profile and reinforced adhesive.

Application areas and relevant industrial sectors

The 3M™ SJ3572 Hook Tape is designed for demanding environments where traditional fasteners reach their limits. Its nylon hook side withstands repeated fastening/unfastening cycles without losing effectiveness.

In the automotive industry, it secures trim panels, cables, and interior protections. It supports vibrations and temperature fluctuations without peeling.

In the electronics and electrical engineering sector, it organizes and secures cable bundles in cabinets or equipment. The fastening is clean, tool-free, and reversible.

Furniture and interior design also benefit from this tape: fastening decorative panels, wall coverings, or temporary signage. Removal does not leave marks on surfaces.

In the medical sector, it secures light equipment or removable protections, where clean and hygienic fastening is essential.

Other user sectors:

• Aerospace: lightweight fastening of interior protections and panels
• Signage and visual communication: rapid installation and removal of supports
• Logistics: securing documents or labels on containers
• Construction and finishing work: fastening profiles, seals, or flexible insulation

At Dagobert Industrie, we offer this tape to all professionals who need a reliable, clean, and removable industrial hook-and-loop fastening, regardless of the business sector.

Comparison: SJ3572 versus other 3M™ hook tapes in the Dual Lock and SJ range

Comparative table of 3M™ references for mechanical fastening

3M™ Reference	Type	Material	Shear resistance	Typical usage
SJ3572	Hooks only	Nylon	High	Industrial fastening, panels, equipment
SJ3570	Loops only	Nylon	High	Counterpart to SJ3572
SJ3571	Hook + loop kit	Nylon	High	Complete, ready-to-use solution
SJ3550 Dual Lock™	Mushrooms (self-fastening)	Polypropylene	Very high	High-frequency repeated fastening, automotive
SJ3560 Dual Lock™	Mushrooms (density 400)	Polypropylene	Maximum	Heavy industrial assembly, vibrations

The Dual Lock™ works using mushrooms that lock into each other: two identical sides are sufficient. The SJ3572 works as a classic hook/loop system, like an industrial velcro.

Dual Lock™ supports heavier loads and resists repeated vibrations better. The SJ3572 offers a smoother release and better compatibility with textiles or foams.

If you already have a looped surface (fabric, carpet, foam), the SJ3572 integrates directly without needing to apply a counterpart. This is its main advantage over Dual Lock™.

Application tips and best practices for use

The performance of the 3M™ SJ3572 Hook Tape depends largely on the quality of surface preparation before application.

Thoroughly clean the bonding surface with isopropanol or a suitable cleaner. Any trace of grease, dust, or moisture significantly reduces the adhesion of the industrial hook-and-loop tape.

Apply the tape at a temperature between 21 °C and 38 °C. Below 10 °C, the acrylic adhesive loses its flexibility, and the initial bond is less reliable.

Apply firm and uniform pressure along the entire length of the tape after application. An application roller or simple prolonged manual pressure for 30 seconds is sufficient.

Wait 24 to 72 hours before subjecting the assembly to a significant mechanical load. The acrylic adhesive reaches its maximum strength after this maturation period.

The SJ3572 is designed to be paired with the 3M SJ3402 loop. Always ensure you use both elements from the same range to guarantee the stated performance.

Here are the most common mistakes to avoid:

• Applying the tape to an unprepared or friable painted surface
• Cutting the tape with unsuitable scissors, which crushes the hooks at the edges
• Immediately exposing the assembly to intense vibrations without letting the adhesive set
• Using a loop of a different brand or weight, which is incompatible with the SJ3572 hooks

FAQ - 3M™ SJ3572 Hook Tape

1. What is the difference between the SJ3572 (hooks) and the SJ3571 (loops)?

The SJ3572 is the hook part of the 3M™ SJ3570 industrial hook-and-loop system. It must be paired with the SJ3571 (loop part) to form a complete bond.

The hooks are the "hard" side: they hook into the textile loops of the complementary side. Both references must be used together to obtain maximum holding strength.

2. To which types of surfaces does this tape adhere correctly?

The SJ3572 works on smooth, clean, and dry surfaces: metal, rigid plastic, glass, varnished wood, composites.

Porous, dusty, or greasy surfaces reduce the adhesion of the acrylic adhesive. Prior cleaning with isopropanol is highly recommended before application.

3. What is the temperature resistance of the SJ3572?

The SJ3572 tape withstands temperatures from -40 °C to +107 °C in continuous use. This is a concrete advantage in industrial environments exposed to heat or cold.

Beyond these thresholds, the acrylic adhesive may lose performance. For extreme conditions, it is best to check compatibility with the actual application.

4. Is this tape reusable?

Yes, the hook-and-loop connection is reusable: the assembly can be opened and closed many times without significant loss of performance.

However, the adhesive on the back of the tape is permanent. Once stuck to the surface, removal may damage the substrate or leave residue.

5. What are the typical industrial applications for the SJ3572?

The SJ3572 is used wherever a removable and repeatable fastener is needed: machine coverings, control panels, cables and conduits, floor protections, industrial signage.

It effectively replaces screws, clips, or rivets in assemblies requiring regular access, while offering a reliable mechanical hold over time.

6. Is a setting time required before loading?

Yes. After application, it is recommended to wait 72 hours before subjecting the assembly to its maximum load. 3M™ acrylic adhesive gradually develops its final strength during this period.

Firm and uniform pressure during application (e.g., with a roller) significantly improves the initial adhesion to the substrate.
