“Golden Age” of plastic models should find it to be an
illustrated history lesson.

When it comes to choosing an adhesive for
our foam models, we are presented with a
number of choices. Typically, the most important concern is
that the product doesn’t attack the foam and melt or deform
it. Bond strength, and if the glue dries clear and stays clear,
are also important considerations.
Foam-Tac from Beacon Adhesives, which has been around
since 1926, meets all of these requirements. We have
successfully used the glue on four foam aircraft that have
been previously reviewed in Model Aviation. They include
the FMS P-51B, a Freewing A- 10, a RocHobby F2G Super
Corsair, and the Dream-Flight Libelle.
The instructions for using Foam-Tac are simple and come
directly from the company’s website:
“All surfaces must be clean, dry, and free of dust and
grease. Remove white cap & save for storage. Screw on
applicator tip & snip. Apply a thin layer of glue to each
side of materials to be joined. Wait a few seconds and then
firmly press parts together and immediately separate for 4-5
seconds more. Rejoin parts, firmly pressing surfaces together
for a permanent bond. Allow to dry for 15-20 minutes. Full
cure within 2-14 hours. Always replace the flat white cap
after each use to keep glue from thickening!”
Because Foam-Tac works like a contact adhesive, no
foaming of the glue joint happens while it cures. When
parts to be glued together are momentarily joined and then
separated, it’s best to keep them close together because the
glue will become stringy. If glue gets on the outside of the
joint, it can typically be wiped away.
One of the benefits of Foam-Tac is that it remains flexible,
and can even be used to hinge the ailerons, elevators, and
rudders of foam models. Over time, glue joints have not
shown signs of yellowing. When the models mentioned were
assembled, glue joints were given 15 to 20 minutes to dry
before handling the model, and the completed aircraft was
allowed to cure overnight before being flown.
Vapors from the glue do not seem to be as irritating as
some other adhesive options; however, prolonged exposure
to vapors in not recommended. All adhesives are best used
in a ventilated area.
Foam-Tac works on Depron, EPP, and EPO foams and can
also be used to glue carbon fiber or balsa to foam.
According to Beacon Adhesives, Foam-Tac is made in
America. The product is safe for short-term contact with the
skin, but is flammable and shouldn’t be used around an open
flame or ignition source.
Foam-Tac can be purchased directly from Beacon
Adhesives, or can be found at several online retailers and
possibly at your local hobby shop. A list of retailers can be
found on the company’s website.
