Industrial Adhesives & Tapes


Attach and detach heavy panels in a snap...again and again!

 Dual Lock

A low key "snap" solved the problem of a metal-on-metal roar, secured a safety perimeter around thrashing robots, and defeated steel screws in a mushroom vs. thread competition.

Dual Lock Rolls

"Snap" is the sound of assurance when pressing together the two sides of a 3M™ Dual Lock™ Reclosable Fastener. That's the sound of hundreds of mushroom-shaped stems interlocking with strength enough to replace screws, nuts, bolts, and other mechanical fasteners in many removable panel applications.

Dual Lock

For example, rather than drill and compromise the integrity of thick sound abatement panels, a manufacturer used 3M™ Dual Lock™ Fasteners to hold the panels to a metal frame around noisy automated assembly equipment. The fasteners resist loosening from the constant vibration unlike a screw or nut and bolt. Another manufacturer attached clear polycarbonate to metal frames enclosing robotic arms in manufacturing cells that workers needed to observe occasionally without getting too close. Moving, reconfiguring, and reassembling the cells was easier with press-on fastening than screwing and unscrewing. On a subway car, convenient 3M™ Dual Lock™ Fasteners replaced screws for suspending maintenance access panels over passengers.

Dual Lock Product Uses

Other applications include securing truck bed covers, fastening solar panels, holding large graphic panels, attaching cover plates on wire channels, and securing cushioned panels in horse trailers.

Five pressure sensitive adhesive-backed versions offer choices for bonding on contact to a variety of flexible and rigid materials. From more than 20 products, designers and manufacturers can also select from a range of closure strength.

Four-step selection process

Four easy steps can help you narrow the range of 3M™ Dual Lock Reclosable Fasteners to a "go-to" selection for testing and evaluation:

  1. Challenge traditional thinking.
  2. Select closure strength based on fastener construction.
  3. Select adhesive performance.
  4. Combine, test, and evaluate.

1. Challenge traditional thinking

With 3M™ Dual Lock™ Reclosable Fasteners you can lose the screws and save the time and work of drilling, tightening, and retightening. At the same time, keep the confidence of knowing you can securely hold together even dissimilar materials, then attach and detach hundreds of times even in tough end use environments.

For improved appearance, reclosable fasteners are hidden beneath surfaces without nail or screw heads, and no holes to invite moisture, corrosion, or dirt. For many applications, sleek appearance is a competitive advantage.

2. Select closure strength based on fastener construction

The number of mushroom caps and stems per square inch depends on the specific 3M™ Dual Lock™ Reclosable Fastener. Select 170, 250, or 400 stems: the higher the combined number, the greater the closure strength.

Dual Lock Strength Increase

Holding strength increases with larger areas of fastener coverage.

3. Select adhesive performance

For the application ease of a PSA tape, a variety of adhesive backings are available to meet production and use criteria.

Rubber Adhesives Acrylic Adhesives
· High initial adhesion on contact · Fair initial adhesion on contact
· Bonds to Low Surface Energy materials · Bonds to High Surface Energy materials
· Quick stick · Build-up to strong adhesion
· Good shear strength · High shear strength
· Indoor use · Indoor and outdoor use
· Narrow operating temperature range · Wide operating temperature range
· Fair moisture resistance · Excellent moisture resistance
· Some solvent resistance · Excellent solvent resistance
· Moderate aging performance · Excellent aging performance

Non-adhesive-backed versions are also available on rolls, or as rigid circles and strips.

4. Combine, test, and evaluate

After combining the options for adhesives and stem density, you're ready to test specific products. Trial bags are available for pre-production evaluation.
