Additional Performance
Characteristics
Washing and Dry Cleaning:
The adhesive present on these Dual Lock products typically makes
them unsuitable to washing or dry-cleaning processes
Attachment Techniques
Pressure Sensitive Adhesive attachment:
The fasteners and substrate surfaces should have equilibrated for a
minimum of 1 hour at temperatures of 20 °C or greater before
application. Generally, this adhesive backed fastener should be
applied to surfaces that are smooth, dry and free of oils, mould
release agents or other surface contaminants.
The substrate surface 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: Be sure to follow all government regulations and the
manufacturer’s precautions and directions for use when using
solvents or other cleaning methods.
After the substrate has been cleaned and dried, the liner is removed
from the fastener’s adhesive and without touching the adhesive, the
fastener’s adhesive is applied to the surface using light finger
pressure. The fastener can then be rolled down, to increase contact
of the adhesive with the substrate’s surface, by one of two methods.
Extra care must be exercised when rolling down 3M™ Dual Lock™
Reclosable Fasteners to prevent bending of the stems which can
compromise the closure strength.
The pressure-sensitive adhesive bonds to the substrate on contact
and parts can be handled immediately. Adhesive bond strength
increases with time, pressure and temperature.
A minimum of one hour dwell is recommended before applying a
load or disengaging assembled parts. Recommended time to
achieve maximum bond strength is 24 hours.
Storage & Shelf Life
Store at 16 °C – 25 °C and 40 – 65 % relative humidity in its original
box. The product can be stored up to 18 months after production.
Note: The shelf life may be shortened if the original packaging is
not properly sealed or stored in an environment with high
temperatures or humidity.
