1) Pressure Sensitive Adhesive attachment: The use of pressure sensitive adhesives
eliminates or reduces the need for sewing, solvent activation, dielectric or ultrasonic
bonding and bulk adhesive bonding. This can result in simplicity, greater safety and lower
installation costs. Pressure sensitive products can be applied manually or automatically
using a variety of equipment choices. Contact your 3M Sales Representative to discuss
automated equipment options.
Substrate Surface Preparation: Highly textured substrate surfaces may reduce the
ultimate adhesion levels and care should be given to minimize the surface texture or
roughness. Adhesive backed 3M™ Reclosable Fasteners such as 3M™ Scotchmate™
products should be applied to surfaces that are clean, dry, and free of oil, grease, dust, mold
release agents or other 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: When using cleaning agents such as solvents or abrasives, it is important to follow all
In exceptional cases, especially when removing silicone mold release agents or on rough or
porous surfaces, it may be necessary to sand or abrade the surface, use an adhesive primer,
or surface sealer to optimize bond performance. The selection of priming or sealing
materials will depend on both the substrates and the environmental conditions the product
will be exposed to during use.
Attachment Procedure: To obtain an optimum bond to any surface, both the fasteners and
the target surface should have equilibrated at temperatures between 70°F (21°C) and 100°F
(38°C) for a minimum of 1 hour before application. Remove the adhesive liner and without
touching the adhesive apply the adhesive side of the fastener to the pre-cleaned and
prepared surface. Using finger pressure, press the fastener onto the substrate to obtain initial
surface contact between the adhesive and substrate. If the substrate is flexible, make sure it
is laying on a hard flat surface so as to permit uniform application of the adhesive. Use of a
rubber hand roller, press platen or similar device is recommended to ensure full contact of
adhesive with the substrate. Three passes in each direction, with special attention paid to
rolling down the edges, should be adequate.
Dwell Time before Handling or Applying a Load: Parts with properly chosen and
applied reclosable fasteners with pressure sensitive adhesives can be handled immediately.
Adhesive bond strength increases after application with time, pressure and/or temperature,
as the adhesive further wets out the substrate surface. Once attached to the substrate, a
1-hour minimum dwell time is recommended before applying a load or disengaging.
This dwell time is important for achieving a firm adhesive bond before applying a load
or using. This adhesive achieves approximately 50% of the ultimate bond strength within
20 minutes, 90% after 1 hour and the ulitmate bond strength is obtained within 24 hours
at 72°F (22°C) and 50% relative humidity. The use of primers or adhesion promoters may
reduce the time required to achieve the ultimate bond strength.
