Pr oduc t Descr ipt ion These specially formulated 3M™ Hook and Loop Reclosable Fasteners offer

value pricing while giving you basic closure alternatives to zippers, screws, snaps,

hooks and more. These Hook and Loop Fasteners engage easily with minimal

pressure to form a quick fastening attachment, simply pull the strips apart by hand

to disengage.

These hook and loop fasteners are available coated on the backside with a rubber

based pressure sensitive adhesive or non-coated for sewing applications.

Design Considerations • You will need to determine how much fastener will be needed to support your

application, however 4 square inches of 3M™ Reclosable Fastener to support

1 pound of weight is our general suggestion.

• Rounding the corners of the fastener, slightly recessing the product into the

surface or providing raised edges around the Reclosable fastener can reduce the

possibility of edge lifting and improve the overall appearance of the fastener on

the finished product.

• These hook and loop Reclosable fasteners should be applied to surfaces that are

clean, dry and free of oil, grease, dust, mold release agents or surface

contaminants that could reduce the adhesion.

• To obtain an optimum bond to any surface, both the fasteners and the target

surfaces should have equilibrated for a minimum of 1 hour at temperatures

between 68°F (20°C) to 90°F (32.2°C) before application. The liner protecting

the adhesive is removed and preferably without touching the adhesive, the

fastener is applied to the surface to obtain initial contact between the adhesive

and substrate. Exposure of the adhesive to ambient conditions without the

protective liner, before applying to the surface, should be minimized as initial

adhesive tack may decrease. Flexible materials should be lyin g on a hard flat

surface so as to permit uniform adhesive contact with the surface. Use of a

rubber hand roller, press platen or similar device is recommended to ensure full

adhesive contact with the surface. Approximately 4.5 pounds of force per square

inch, (310 grams per square centimeter) is recommended to increase adhesive

contact, improving bond strength. For all adhesive applications, it is important

to ensure that the edges are rolled down to reduce the chance of edge lifting.

• It is essential that the user evaluate this product to determine whether it is fit for

a particular purpose and suitable for the user’s method of application

Performance

Characteristics Note: The following technical information and data should be considered representative

or typical only and should not be used for specification purposes.

Solvent Resistance: The plain backed nylon/polyester components resist occasional

attack by most common solvents and alkaline solutions. Acid solutions may cause

deterioration of the fastener. The adhesive on 3M™ Hook and Loop Reclosable

Fasteners SJA7501 and SJA7502 m ay be compromised by many comm on laboratory

solvents and transportation fluids (gasoline, motor oil, etc.). Where solvent

resistance is important it is suggested that the customer evaluate 3M™ Hook and

Loop SJ3571, SJ3572, SJ3576, SJ3577 or many of our 3M™ Dual Lock™

Reclosable Fastener products to determine if the actual adhesive performance meets

their application requirements.

Plasticizer Resistance: The adhesive on Reclosable fasteners SJA7501 and

SJA7502 is not recommended for attaching to many common flexible vinyl’s or

other materials containing plasticizing materials. If plasticizer resistance is desired

3M™ Hook and Loop SJ3522 and SJ3523 or many of our Dual Lock products can

be evaluated.

Flammability Resistance: If you need 3M™ Reclosable Fasteners that meet many

the standard flammability tests (such as FAR 25.853) SJ3418FR, SJ3419FR,

SJ3486FR and SJ3487FR for sewing applications and SJ3518FR, SJ3519FR,

SJ3586FR and SJ3587FR for pressure sensitive applications.

Environmental Effects: Temperature as low as -20°F (-29°C) increase s the typical

closure strengths. The adhesive on 3M™ Hook and Loop Reclosable Fasteners

SJA7501 and SJA7502 has not been formulated to withstand varying temperature,

humidity and ultraviolet exposure conditions. If applications such as exposure to

high temperatures, humidity or ultraviolet light are desired, our 3M™ Scotchmate™

SJ3571, SJ3572, SJ3576 or SJ3577 or many of our Dual Lock products, such as

SJ3560, may be evaluated.

Application Ideas • 3M™ Hook and Loop Reclosable Fasteners SJP7401 and SJP7402 can be used in

sewing applications where average strength fasteners will be sufficient.

• 3M™ Hook and Loop Reclosable Fasteners SJA7501 and SJA7502 provide a

rubber based adhesive solution for applications at ambient temperatures where

minimal adhesive requirements occur. Because product performance will depend

on actual conditions within any specific application, it is essential that the user

evaluate the 3M product to determine whether it is fit for a particular material

purpose and suitable for the user’s method of application.

• This product is non-returnable so verify that it performs to your requirements.
