Product Descri pti on 3M™ Hook and Loop Fasteners consist of hooks and loops which engage to form a
quick fastening attachment and offer advanced closure alternatives to zippers,
screws, snaps, hooks, etc. They offer greater design flexibility, faster product
assembly, smoother and cleaner exterior surfaces and improved product performance
in many applications by simply pulling the strips apart by hand to disengage.
Thin Products

loop fastener which can wrap around and attach to itself to be used for
bundling items. One side of the fastener is covered with tiny polypropylene
translucent hooks, about 1400 per square inch. These hooks can engage
with thousands of soft pliable thin polyester loops on the reverse side.
Available in Red, Black, and White.

Attachment Techniques The following information is intended to assist the designer considering the use
of adhesive-coated 3M™ Hook and Loop Fasteners. System product
performance depends upon a number of factors, including the fastener (material,
adhesive and area), application method, 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 Consi de r at ions As a general rule, four square inches of fastener adhesive 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 two most common techniques for attaching these 3M™ Hook and Loop™
Fasteners to various surfaces are summarized below.
1) Pressure Sensitive Adhesive attachment: The use of pressure sensitive
adhesives eliminates or reduces the need for sew ing, 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.

3M™ Hook and Loop Fasteners Trial Bags
Surface Preparation Highly textured surfaces may reduce the ultimate adhesion levels and care should be
given to minimize the surface texture or roughness. Adhesive backed 3M™ Hook
and Loop Fasteners should be applied to surfaces that are clean, dry and free of oil,
grease, dust, mold release agents or surface contam inants that could reduce the
adhesion. It is recommended to remove any surface contam inants 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 Substrate 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 substrate.
The selection of abrasion, priming or sealing methods will depend upon the substrates
and the environmental conditions the product will be exposed to during use.
Attachment Techniques 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 tem p eratures betw een 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
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 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 or wet-out
with the substrate 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 im portant to ensure that
the edges are rolled down to reduce the chance of edge lifting.
Storage Store in original packaging between 60° to 80°F (16° to 27°C) and 40 to 60%
relative humidity.
