Adhesives: Surface Preparation
and facility surroundings. It is
estimated that even a thin film of oil
will reduce adhesive performance by
as much as 60%. Applying a cleaner,
isopropyl alcohol or a degreasing
solvent such as Loctite 7063 will
remove dirt and debris.
Roughing up the substrate
Giving the substrate a rough abrasive
workover with sandpaper or a wire
brush will remove heavy deposits as
well as creating a surface area with
greater peaks and valleys, which has
the effect of giving the adhesive more
to grip to and increasing adhesive
properties. Degreasing should take
place before and after the abrasion
process.
Applying a primer
Some materials are
notoriously hard to bond, like
polyethylene, polypropylene,
polytetrafluoroethylene (PTFE) and
thermoplastic rubber materials. If
that is the case, applying a polyolefin
primer such as Loctite 770 can
increase the surface energy of
these substrates so adhesives bond
more effectively. Apply by spraying,
brushing or dipping
at ambient temperature.
Applying an activator
You can apply an activator to
speed up the curing time of certain
adhesives on inactive surfaces.
For example, Loctite 7452 can be
used for cyanoacrylate adhesives to
ensure rapid fixturing, and can
be post or pre-applied.
SF 7063 Cleaner
Aerosol
Loctite SF 7063 is a general-purpose solvent-
based product for cleaning and degreasing all
kinds of surfaces and machinery components
before applying Loctite adhesives. Loctite 7063
removes most greases, oils, lubricating fluids,
metal cuttings, etc., and leaves no residue.

SF 7649 Activator
This Loctite SF 7649 activator is designed
to promote the curing speed of anaerobic
adhesives and sealants without any
significant loss of joint strength. It is ideal
for applications with passive metals or
inert surfaces and with large bond gaps
and is particularly recommended when the
application temperature is below 15 °C.

SF 7386 Multi Bond
Activator
Loctite SF 7386 is a transparent, yellow
to light amber liquid activator designed
to initiate the cure of toughened acrylic
adhesives. The fixture time and cure speed
depend on the adhesive used, the substrate
bonded, surface cleanliness and whether
one or two-surface activation is used.

SF 7471 Activator
Loctite SF 7471 is a transparent, yellow
to amber liquid activator used where
increased cure speed of anaerobic
products is required. It is especially
recommended for applications with passive
metals or inert surfaces and with large bond
gaps and when the prevailing temperature is
low (<+15 °C).
