Scotchmate
Pressure Sensitive Adhesive attachment: The 3M™ Scotchmate™ Reclosable
Fasteners and adherend surfaces should have equilibrated for a minimum of 1 hour at
temperatures of 68°F (20°C) or greater before application. These adhesive 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 remove any surface contaminants with an appropriate
cleaning method for the customer’s substrate, type and quantity of surface contaminants
that need to be removed. Note: Follow the manufacturer’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 adhesive, the Scotchmate reclosable fastener is applied to the surface using firm
roller pressure to help ensure complete adhesive contact to substrate. Adhesive bond
strength increases with time, as the adhesive flows into the substrate structure. Handling
strength is achieved immediately. Approximately 50% of ultimate bond strength is
achieved at room temperature in the first 20 minutes, 90% after about 24 hours and
100% after about 72 hours for acrylic adhesives. 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 fabric 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
adhesive side of the Scotchmate reclosable fastener fastener through the fabric 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
evaluate 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:
Mechanical Attachment: The bond strength can be increased by mechanically
attaching it to difficult to adhere to surfaces such as textured plastics and wood by using
staples. Alternatively 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 sewing 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 fabrics with ultrasonic sealing equipment. This method can be used to provide
straps and other fabricated forms.
