Scotchmate™Reclosable Fasteners
SJ3526N and SJ3527N Family
Nylon Hook and Loop
Product Description 3M™ Scotchmate™ Reclosable Fasteners offer closure alternatives to zippers, screws, snaps,
hooks, bolts and more. They offer greater design flexibility, faster product assembly, smoother
and cleaner exterior surfaces and improved product performance in many applications. The hook
and loop fasteners consist of two strips of nylon fabric which engage to form a quick fastening
attachment. Simply pull the strips apart by hand to disengage.
The woven hook is covered with flexible J shaped hooks, about 300 hooks per square inch
(46/sq. cm.) protruding up from a woven backing. The woven loop backing is covered with
thousands of soft, pliable napped loops, providing for thousands of openings and closings
(cycles). The hook and loop are preshrunk to insure maximum dimensional stability and flatness.
These Scotchmate reclosable hook and loop fasteners are coated on the backside with a firm
synthetic rubber pressure sensitive adhesive designed to function for indoor applications. This
adhesive is especially suited for attachment to low surface energy substrates such as
polyethylene, polypropylene, etc.
The hook product is available with a marked product splice making splice identification easier,
allowing splice removal if desired. The product number is SJ3526NFSR. These products are
also available with a brown, 83 pound polykraft paper liner. The paper liner allows easier
diecutting of pieces. The hook is available as SJ3526NP and the loop as SJ3527NP. When
shorter lengths are desired for evaulation, prototypes or small jobs a mini-pack containing a
4.9 yards (4.5 meters) roll of each SJ3526N (hook) and SJ3527N (loop) is available as a single
package, MP3526N/27N.

Note: Long Term Static Load: Conditions such as temperature variations, engagement area, closure pressure and vibrations or
side to side movement after engagement or exposure to prolonged periods of moisture, ultraviolet or other environmental factors
can affect the closure strength and long term static load performance. Reclosable fasteners may slip or creep in the direction of
the static load forces when subjected to static loads at temperatures or weights greater than indicated. The user is responsible for
designing the amount of fastening area based upon the specific conditions for the application. Four square inches of fastening
area per pound (57.3 sq. cm/kilogram) of static load is suggested as a starting point for such evaluations.
a) System performance tests are determined by measuring the performance of the entire mated reclosable fastener system consisting of
two non-anodized aluminum plates joined together with the indicated fasteners. The “T” peel test only measures the closure performance
per ASTM D5170 and was not adhered to aluminum panels. The 90° peel has one of the mated fasteners attached to a non-anodized
aluminum plate while the other mated fastener is not attached to a adherend and is disengaged at a 90° angle.
b) The use of 3M™ Scotchmate™ Loop Reclosable Fasteners engaged to 3M™ Dual Lock™ Reclosable Fasteners provides increased
strength over standard Scotchmate reclosable fasteners, with a limited number of reclosures compared with Scotchmate systems. Due
to the very high strength of Scotchmate reclosable fasteners mated to Dual Lock reclosable fasteners, extra care should be given to
ensure the maximum bond strength is obtained to the adherends being joined. Failure to obtain bond strengths sufficiently high to the
adherend may cause the fastener’s adhesive to release from the adherend.
c) 3M™ Scotchmate™ Reclosable Fasteners SJ3526N and SJ3527N and SJ3540 are engaged with firm pressure and disengaged, peeled
or cleaved at the rate of 12 inches (305 mm) per minute.
d) The engaged thickness was measured using a 0.5" diameter pressure foot supporting a 34 gram weight. Engaged thickness per given
fastener area will decrease when compressed or increase with no load or when the engaged are separated in tensile.
e) Cycle Life is the number of cycles (openings and closings) that the fastener is subjected to while maintaining 50% or greater of the initial
peel value.

Performance
Characteristics
Solvent Resistance: The nylon components resist incidental attack by most common
solvents and alkaline solutions. Acid solutions may cause deterioration of the fastener.
The adhesive on 3M™ Scotchmate™ Reclosable Fasteners SJ3526N and SJ3527N
may be affected by many common organic solvents and transportation fluids
(gasoline, motor oil, etc.). If increased solvent resistance is desired the customer is
directed to evaluate 3M™ Scotchmate™ Reclosable Fasteners SJ3571 or SJ3572 or
many of our 3M™ Dual Lock™ Reclosable Fastener Products to determine if the
actual adhesive performance meets the requirements of their application.
Plasticizer Resistance: The adhesive on Scotchmate reclosable fasteners SJ3526N
and SJ3527N may be affected by plasticizers found in many common flexible vinyl
and other materials, resulting in adhesive softening or adhesion loss with time. These
products are not recommended for adhering to plasticized materials. If plasticizer
resistance is desired then 3M™ Scotchmate™ Reclosable Fasteners SJ3522 or
SJ3523 or many of our Dual Lock reclosable fastener products may be evaluated to
determine if the actual adhesive performance meets the requirement of their
application.
Flammability Resistance: Scotchmate reclosable fasteners SJ3526N and SJ3527N
will not pass common flammability tests when tested unattached to an adherend. If
you need 3M™ Reclosable Fasteners that meet many of the standard flammability
tests (such as FAR 25.853, FMVSS-302, ASTM E-162, ASTM E-662, BSS-7239 and
others), it is suggested that you refer to the product selection guide 3M™ Flame
Resistant Reclosable Fasteners.
Environmental Effects: Temperatures down to -20°F (-29°C) increases the typical
closure strengths. The Scotchmate reclosable fasteners SJ3526N and SJ3527N
adhesive is formulated to withstand typical indoor conditions temperature, humidity
and ultraviolet exposure conditions. If your application requires increased
ultraviolet exposure or outdoor performance review the 3M™ Scotchmate™ or
3M™ Dual Lock™ product selection guide to determine products that may meet
your requirements.
Water (Humidity) Resistance: Closure strength of nylon hook and loop fasteners
decreases after prolonged exposure to water due mainly to water absorption by the
cut nylon ends for hook products. Closure strength is regained when dried. Review
the “3M™ Scotchmate™ Polyester Reclosable Fasteners” product selection guide
(70-0709-3962-7) for Scotchmate reclosable fastener products with greater resistance
of the closure to moisture. Once bonded the adhesive has high resistance to moisture
under typical use conditions.
Volatile Outgassing: Volatile outgassing, as per ASTM E595, is one important test
in determining the suitability of materials for usage within spacecraft. Generally
products with acrylic or no adhesive have lower volatile outgassing values.
Scotchmate reclosable fasteners SJ3526N and SJ3527N have not been tested and
would not be expected to pass ASTM E595. Products tested at the Goddard Space
Flight Center can be found at the following web site: http://outgassing.nasa.gov/

Sterilization/Autoclaving: 3M™ Scotchmate™ Reclosable Fasteners SJ3526N and
SJ3527N have not been tested for performance after gas or steam sterilization, or
autoclaving.
Washing and Dry Cleaning: Washing or dry cleaning of these products is not
recommended due to the potential for adhesive softening, that could transfer adhesive
residues to other materials, or reduce long term performance.
Fungus Resistance:
Mil standard 810F, Method 508.5: Three samples from one lot of Scotchmate
reclosable fasteners SJ3526N and SJ3527N were exposed to five fungal organisms
(Aspergillus versicolor – ATCC 11730, A. flavus – ATCC 9643, A. niger – ATCC
9642, Penicillium funiculosum – ATCC 11797, and Chaetomium globosum –
ATCC 6205) and gave an average fungal growth rating after 44 days of 2.0 for
Scotchmate reclosable fasteners SJ3526N and 2.7 for Scotchmate reclosable
fasteners SJ3527N.
ASTM G21-96 “Fungal Challenge Test”: Three samples from one lot of
Scotchmate reclosable fasteners SJ3526N and SJ3527N were exposed to five
fungal organisms (Aspergillus niger – ATCC 9642, Penicillium funiculosum –
ATCC 11797, Chaetomium globosum – ATCC 6205, Trichoderma virens ATCC
9645 and Auerobasidium pullulans ATCC 15233). Scotchmate reclosable fastener
SJ3526N had an average fungal growth after 7, 14, 21 and 28 days of 2.0, 2.0, 2.3
and 2.3 respectively, whereas Scotchmate reclosable fastener SJ3527N gave an
average rating of 2.3, 2.7, 2.7 and 2.7 for the same time periods.
Static Discharge: Scotchmate reclosable fasteners SJ3526N and SJ3527N have
not been tested for static charge released during liner removal, closure opening nor
adhesive removal from adherends after attachment of the fastener. If your
application requires use of these fasteners in areas where static discharge is of a
concern, the fasteners should be tested under expected use conditions.

Attachment
Techniques The following information is intended to assist the designer considering the use of adhesively
coated 3M™ Scotchmate™ Reclosable Fasteners. System product performance depends
upon a number of factors, including the fastener (material, adhesive and area), application
method, adherend surface characteristics (material, texture and cleanliness), environmental
conditions (moisture, ultraviolet and temperature exposure) plus the time it is expected to
support a given load. Because many of these factors are uniquely within the user’s knowledge
and control, it is required that the user evaluate 3M products to determine whether they are fit
for a particular purpose and suitable for the user’s substrates, method of application and
desired end use.
Design Considerations: As a general rule, four square inches of fastener area per pound
(57.3 square centimeters per kilogram) of static load to be supported is suggested as a starting
point for evaluation. More or less area may be needed depending on specific conditions or
end use applications.
Rounding the corners, slightly recessing the product into the substrate 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. Mechanically securing the
corners of the fastener with rivets, staples, screws, etc. may also reduce the possibility of
edge lifting, but may reduce the closure performance.
The three most common techniques for attaching these 3M™ Scotchmate™ Reclosable
Fasteners to various surfaces are summarized below. For complete details on techniques and
options for attaching 3M™ Scotchmate™ or Dual Lock™ Reclosable Fasteners please see
the technical bulletin Attachment of 3M™ Scotchmate™ and Dual Lock™ Reclosable
Fasteners (70-0709-3929-6).
1) Pressure Sensitive Adhesive attachment: The use of pressure sensitive adhesives
eliminates or reduces the need for sewing, solvent activation, dielectric or ultrasonic bonding
or bulk adhesive bonding. This can result in simplicity, improved safety and lower installation
costs. Pressure sensitive adhesive products can be applied manually or automatically using a
variety of equipment choices. Contact your 3M sales representative to discuss automated
equipment options.
Adherend Surface Preparation: Highly textured adherend surfaces may reduce the ultimate
adhesion levels and care should be given to minimize the surface texture or roughness.
Adhesive backed Scotchmate 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. It is recommended to remove any surface contaminants that may reduce
adhesion by using a method suited for the type and quantity of surface contaminants present.
Note: It is important for the customer to follow all manufacturer’s precautions and
directions for use as well as any specific government regulations or customer and
supplier requirements for the method(s) used to remove any contamination on the
surface of the adherend or preparing the surface for attaching the fastener(s).
In exceptional cases, especially when removing silicone mold release agents or on rough,
porous surfaces, it may be necessary to lightly abrade the surface, use an adhesion promoter,
or surface sealer to optimize the adhesive bond to the adherend. The selection of abrasion,
priming or sealing methods will depend upon the adherends and the environmental conditions
the product will be exposed to during use.

Attachment
Techniques
(continued)
Attachment Procedure: 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 100°F (38°C) before application. The liner protecting the adhesive is removed and
preferably without touching the adhesive, the fastener is applied to the adherend to obtain initial
contact between the adhesive and adherend. 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 adherends should be lying 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 adherend 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.
Dwell Time before Handling or Applying a Load: Parts with properly chosen and applied
pressure sensitive adhesive reclosable fasteners can be handled immediately. As the adhesive
further wets-out the adherend surface, adhesive bond strength increases after application with
time, pressure and/or temperature. Once attached to the adherend, a 1-hour minimum dwell
time is recommended before applying a load or disengaging mated Scotchmate reclosable
fastener pieces. This dwell time is important for achieving a firm adhesive bond before
applying a load or using. The adhesive on 3M™ Scotchmate™ Reclosable Fasteners SJ3526N
and SJ3527N family of products achieves approximately 50% of the ultimate bond strength
within 20 minutes, 90% after 1 hour and the ultimate bond strength of properly applied
fasteners is obtained within 24 hours at 72°F (22°C) and 50% relative humidity. Primers or
adhesion promoters may reduce the time required to achieve the ultimate bond strength.
2) Heat (Press) Bonding: Scotchmate reclosable fasteners SJ3526N and SJ3527N family of
products can be attached to many fabric and foam articles by a process called heat or press
bonding. The fastener is initially adhered to the article using finger pressure. The fastener is
held in place with the pre-applied adhesive and bond strength is increased by applying heat
and pressure through the adherend to the adhesive side of the fastener at previously
determined pressure, times and heating periods. For properly chosen press bonding
conditions, the product can be used immediately after cooling, usually a matter of minutes.
Once applied these fasteners should not be washed or dry cleaned. Product performance will
depend upon the nature of the fabric or foam as well as other conditions within any specific
application. For this reason it is essential that the user evaluated the product to determine if it
is fit for a particular purpose and suitable for the user’s method of application.
Typical Press Bonding Conditions:
Bonding Temperature: 250 to 425°F (121 to 218°C)
Bonding Pressure: 30 to 100 psi (207 to 690 kPa)
Bonding Time: 3 to 30 seconds.
3) Mechanical Attachment: Scotchmate reclosable fasteners SJ3526N and SJ3527N family
of products may also be mechanically attached to difficult to adhere to surfaces such as
textured plastics and wood by using staples, screws, rivets and similar methods. The head of
the mechanical fastener should be flat and large enough to resist pull through when the
fastener is disengaged. The head of the fastener should also be recessed as much as possible
below the surface of the hook or loop to prevent interference with (dis)engagement properties.
The use of resin coated chisel divergent staples appear to provide excellent attachment to
thick sections of soft and hardwood surfaces.
