M.A.P. for Fastening Success...
simple 4-step process
With this step-by-step guide you can more easily

and closing, attaching and detaching.
Consider even converting a permanent closure
to reclosable one.
Step 3: Select adhesive performance
Select from multiple adhesive backings to best
match different substrates and environmental
conditions. Or, select plain-backed versions.
Step 1: Challenge traditional thinking
Lose the screws. Consider 3M Reclosable
Fasteners to replace screws, bolts, nails, rivets,
welds, and other traditional fastening methods in
many applications involving repeated opening
™
Step 2: Select closure strength
Based on the specific construction of each 3M
™
Reclosable Fastener, select from a wide range
of holding strength to match the weight of
surfaces and stresses of use.
Step 4: Combine, test, and evaluate
Combine closure strength and adhesive
performance to determine the right fastener(s)
for testing and evaluation. See charts on pages
6-8.
1. Challenge
traditional
thinking
Lose the screws...
as wells as
the nuts and
bolts, snaps,
latches,
nails, zippers,
clasps,
wingnuts,
and welds.
Think 3M First for expanded options to improve design and function
• Range of closure strengths and thicknesses
• Hold together even dissimilar substrates, then
attach and detach multiple times easily
• Choice of plain-backed or pressure sensitive
adhesive-backed to bond to many surfaces
even LSE plastics
• Reliable performance in hot, cold, wet, sunny,
and other difficult environments
• Colors to accent or clear to blend for aesthetics
• Save the weight of metal fasteners
Attach cushioning to
horse trailer divider.
11
Think 3M First for smooth, clean surfaces to improve appearance
• Hidden beneath the surface for greater
design flexibility
• No nail or screw heads, snap caps, weld marks,
or breakable teeth
• Maintain surface integrity with no holes to
invite moisture, corrosion, or dirt
• Sleek appearance for competitive advantage

Invisibly attach fascia
to painted metal valence.
Think 3M First for faster, easier application to save time and labor
• Pressure sensitive adhesive options stick on
contact as quickly and easily as tape for quick
installation without special tools
• No drilling, screwing, tightening, sewing, or
complex process

3M
™
Dual Lock
™
Reclosable Fasteners
• Mushroom-shaped stems on one side of the
fastener interlock with identically shaped stems
on the other side for 5X greater closure strength
than hook and loop; peel apart for opening
• Pressure sensitive adhesive-backed versions*
bond on contact to a variety of flexible and rigid
materials; choice of specialized adhesive
properties (see charts on pages 5-8)
• Choice of stems per square inch:170, 250,
400 (higher the combined number, greater
the closure strength–see chart at right)
• Larger the fastener area, greater the strength
for holding weight and resisting shear and peel
• Low profile option for a snug fit with about
half the thickness of the standard products

3. Select adhesive performance
Rubber, Acrylic, or Non-adhesive
For the application ease of a PSA tape, a variety of adhesive backings are available to meet
production and end use criteria (see charts starting next page). Consider rubber or acrylic.
Rubber Adhesives
Acrylic Adhesives
Surface Energy
• High initial adhesion upon contact
• Quick stick adhesion
• Good shear strength
• Narrow operating temperature range
• Fair moisture resistance in end use
• Some solvent resistance in end use
• Fair UV resistance for indoor use
• Fair initial adhesion upon contact
• Build-up over 72 hours to strong adhesion
• High shear strength
• Wide operating temperature range
• Excellent moisture resistance in end use
• Excellent solvent resistance in end use
• Excellent UV resistance for indoor and
outdoor use
• Excellent aging performance

HSE
High Surface
Energy Substrates
Adhesive “wets out” the surface.
Higher the surface energy, better
the bond performance.
Metal
Copper
Aluminum
Tin
Stainless Steel
Glass
Plastics
• Moderate aging performance
• Bonds well to a variety of LSE materials
• Bonds well to HSE materials
including plastics and powder coated surfaces including metals and HSE plastics

Surface Contact
Rolling down the fastener on a clean and dry substrate increases adhesive flow and contact for more
secure bonding. Contact and adhesion will build over time until reaching ultimate strength.
