SJ3522 1" BLACK (50 YD ROLL) - 3M Electronic Specialty

Product Description 3M™ Scotchmate™ Reclosable Fasteners offer closure alternati v es to zippers, screws,

snaps, hooks, bolts and more. They offer greater design flexibility, faster product

assembly, smoother and cleaner exterior surf aces and impro ved product performance in

many applications. The hook and loop f asteners consist of tw o strips of n ylon f abric

which engage to form a quick fastening attachment. Simply pull the strips apart by hand

to disengage.

The woven hook backing is covered with flexible self supporting 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 loops, providing for

thousands of openings and closings (cycles). The loops can be napped or unnapped

providing higher c ycle life. The hook and loop are preshrunk to insure maximum

dimensional stability and flatness.

These Scotchmate reclosable hook and loop fasteners can be coated on the backside

with v arious pressure sensitive adhesives.

Characteristics

Note: The follo wing technical information and data was collected under controlled

laboratory conditions and should be considered representativ e or typical only and

should not be used for specification purposes.

3M™ Scotchmate™ Reclosable Fasteners derive their strength from the area of

engagement as well as closure pressure. Vibration or side to side movement tends to

improv e closure performance. Closure characteristics are indicated by typical values.

Attachment

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

3M™ Scotchmate™ Reclosable Fasteners. Final product performance depends on

actual conditions, including the fastener selected, the conditions in which the fastener

is applied and the time and environmental conditions in which it is expected to

perform. Because many of these factors are uniquely within the user’s knowledge and

control, it is required that the user evaluate the 3M product to determine whether it is

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

end use.

As a general rule, four square inches of Scotchmate reclosable fastener area per pound

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.

There are typically six different methods for attaching Scotchmate reclosable fasteners

to various surfaces.For complete details on techniques and options for attaching

fasteners, please see Attachment of 3M™ Scotchmate™ and Dual Lock™ Reclosable

Fasteners technical bulletin (70-0709-3929-6). The most important techniques for

these Scotchmate reclosable fastener products are summarized on page 5.

Attachment

Techniques

(continued)

Pressure Sensitive Adhesi ve attachment: The 3M™ Scotchmate™ Reclosable

Fasteners and adherend surf aces should have equilibrated for a minimum of 1 hour at

temperatures of 68°F (20°C) or greater before application. These adhesi ve backed

Scotchmate reclosable fasteners should be applied to surfaces that are smooth, dry and

free of oils, mold release agents or other surface contaminants.

The adherend should be cleaned to remov e an y surf ace contaminants with an appropriate

cleaning method for the customer’s substrate, type and quantity of surf ace contaminants

that need to be remov ed. Note: Follow the manuf acturer’s precautions and directions for

use of the cleaning method(s) chosen.

After the adherend is clean, the liner is removed from the fastener and without touching

the adhesi ve, the Scotchmate reclosable fastener is applied to the surface using firm

roller pressure to help ensure complete adhesi ve contact to substrate. Adhesive bond

strength increases with time, as the adhesi ve flows into the substrate structure. Handling

strength is achie ved immediately. Approximately 50% of ultimate bond strength is

achie ved at room temperature in the first 20 minutes, 90% after about 24 hours and

100% after about 72 hours for acrylic adhesi ves. For the rubber based adhesives, 100%

bond strength is obtained in about 24 hours.

Heat (Press) Bonding: 3M™ Scotchmate™ Reclosable Fasteners SJ3526N, SJ3530,

SJ3519FR and SJ3532N hook and SJ3527N, SJ3529, SJ3518FR, SJ3531 and SJ3533N

loop can be attached to many f abric and foam articles with a technique called press

bonding. The Scotchmate reclosable fastener is adhered to the article, as indicated

above, and bond strength is increased by typically applying heat and pressure to the

adhesi ve side of the Scotchmate reclosable fastener fastener through the f abric or foam

article. Equipment can range from a simple household laundry iron to commercial press

units. Product performance will depend on the nature of the fabric or foam and other

conditions within any specific application. For this reason it is essential that the user

e valuate the Scotchmate reclosable fastener 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

Mechanical Attachment: The bond strength can be increased by mechanically

attaching it to dif ficult to adhere to surfaces such as te xtured plastics and wood by using

staples. Alternati vely wood products can be sealed and pressure sensitive adhesive

backed fastener applied as discussed above.

Sewing

3M™ Scotchmate™ Plainbacked Reclosable Fasteners can be attached with manual or

semi-automatic se wing machines, generally utilizing the same thread used in the

garment or fabric. Six to ten stitches per inch (25.4 mm) is suggested. These products

are washable and dry cleanable.

Ultrasonic Bonding

Scotchmate plainbacked reclosable fasteners can be bonded to themselves or other

nylon f abrics with ultrasonic sealing equipment. This method can be used to provide

straps and other fabricated forms.

General Inf ormation 3M™ Scotchmate™ Pressure Sensiti v e Reclosable Fasteners can be bonded to a wide

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

the Scotchmate product to determine if it is fit for a particular purpose and suitable for

the user’s method of application.

a. When attaching to plasticized vinyl (flexib le PVC), evaluation for plasticizer migr ation is recommended.

of plasticizer oils indicated b y softness or oozing of the adhesive.

Choosing Polyester or Nylon Reclosable Fasteners

3M™ Scotchmate™ Reclosable Fasteners are available in polyester or nylon hook

and loop configurations. There are performance and use differences that may be

experienced when using these products. The following table lists the differences
