Reclosable Fastener SJ3000

Thin Hook and Loop Back-to-Back

Pr oduct Information September, 2010

Pr oduc t Descr ipt ion 3M™ Reclosable Fastener SJ3000 is a thin back-to-back fastener that offers closure

alternatives to plastic wire, tape, string, rubber bands and other types of closure

systems used to secure bundles of items. Reclosable Fastener SJ3000 offers design

flexibility, fast product assembly and improved product performance in many

applications.

One side of the thin fastener strip is covered with tiny translucent polypropylene

hooks, approximately 1400 per square inch (220/sq. cm.). These hooks can engage

with thousands of soft, pliable, thin polyester loops on the reverse side providing

for a limited number of openings and closings (cycles). The thin loop is designed to

easily engage with reclosable fastener SJ3000 hook and possibly other small hooks.

The hook may also engage with many other loop materials. This forms a quick

fastening attachment system. Simply pull the strips apart to disengage.

Unless stated, typical system performance characteristics were measured under controlled laboratory

conditions of 72°F ± 5°F (22°C ± 2.7°C) and 50% ± 10% relative humidity. The user should evaluate

products in the actual application to ensure suitable performance for the intended use.

Additional

Performance

Characteristics

Chemical Resistance: The polypropylene hook and polyester loop resist incidental attack

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

of the loop. Small amounts of oils, mold release agents would not be expected to cause

performance issues when in contact with 3M™ Reclosable Fastener SJ3000, except for

the possible difficulty in starting a wrap.

Plasticizer Resistance: The polypropylene hook and polyester loop should have good

resistance to direct contact with most plasticized materials.

Flammability Resistance: Reclosable Fastener SJ3000 will not pass common

flammability tests when tested unattached to an substrate. If you need reclosable

fasteners to meet many of the standard flammability tests (such as FAR 25.853,

FMVSS-302), you may want to consider using 3M™ Reclosable Fasteners

SJ3418FR/19FR, SJ3518FR/19FR and SJ3486FR/87FR.

Water (Humidity) Resistance: Closure strength should be minimally affected by high

humidity conditions.

Thin Hook and Loop Back to Back

Attachment Techniques The following information is intended to assist the designer considering the use of

3M™ Reclosable Fastener SJ3000. It is recommended that the user evaluate 3M

products to determine whether they are fit for a particular purpose and suitable for

the user’s materials, method of application and desired end use.

Reclosable fastener SJ3000 can easily be cut to desired dimensions and shapes per

application need. The product is often used in rectangular strips 1/2" width by

appropriate length required to wrap at least one and one half times around item(s)

being bundled plus a 0.5 inch (1.3 cm) tab or flag. A common formula for

determining desired length is:

(Bundle or item circumference in inches ) x (1.5) + 0.5 inch

(Bundle or item circumference in centimeters) x (1.5) + 1.3 cm

While reclosable fastener SJ3000 is more flexible than many common bundling

materials, care should be exercised in wrapping bundles that have very small

diameters, lest flagging of the end will occur, possibly leading to premature

disengagement. To prevent premature or undesirable flagging a small quantity of a

curable liquid adhesive, hot melt, epoxy or similar material could be applied

joining the exposed end of the fastener with the underlying fastener. This method

will make it more difficult to easily disengage the fasteners.

Rounding the corners can reduce the possibility of edge lifting or flagging while

improving the overall appearance of the fastener on the finished product.

Mechanically securing the corners of the fastener with rivets, staples, screws, etc.

may reduce the closure performance.

Material Surface Preparation: Textured or rough surfaces, especially those that

may engage with a hook or loop can allow easier starting of a wrap around an

object(s). Very smooth surfaces may cause slippage or difficulty in starting the

wrap. In that case the surface could be roughened, or small strips of 3M™

Reclosable Fasteners SJ3506 or SJ3507 could be first applied to the surface.

Surfaces containing oils, mold release agents or other coatings and materials that

can create a slippery surface should be avoided due to possible difficulty in getting

the wrap started, or slipping in usage. It is recommended to remove any surface

contaminants that may cause slippage or problems with starting the wrap by using a

method suited for the type and quantity of surface slip agent present.

Engagement Procedure: Highly porous, soft or fragile materials such as some

vegetables or foam materials may crush or collapse if too high of a pressure is

applied during bundle wrapping. Approximately 2 pounds per inch width (0.4

kilograms per centimeter width) is required for engaging reclosable fastener

SJ3000 to itself. For all applications, it is important to ensure that an acceptable

amount of overlap at the end of the fastener is provided to prevent premature

unwrapping or flagg ing .

The most common technique for attaching reclosable fastener SJ3000 is to wrap

the product upon itself, forming the closure system to bundle items together,

provide surface protection or to secure items during transport. To ensure full

fastener strength the fastener should be completely overlapped, not spiral would

unless the reduced engaged surface area is taken into account.
