They *insist* on there being an expiration date,

The two year life is apparently the longest that the GSA system
will accept for fluids of this sort.

LocTite 7471 composition and expiration

The tech data sheet is there for those who might want it. Acetone is a
large
part of the mix; there is also isopropyl alcohol, plus the active
amine and thiazole
components. Solvents for cleaning, the amine/thiazole for curing kick.

Ellsworth and RS Hughes show small containers as available (1.75 oz.),
~$13-14.

Personal experience: The 7471-T primer has a large effect on the
curing process,
especially where the items being bonded are less chemically active,
such as in
the case of alloy/stainless steels. In the presence of bare aluminum
or brass, this
primer will sometimes cause such rapid curing you can't finish the
assembly. In
the case of less reactive materials, it will enable a far better cure
than you might
otherwise achieve. Much depends as well on the adhesive agent being
used with
the primer. I was assembling a threaded retainer made from brass onto
anodized
aluminum (32 TPI, ~1.5" dia), cleaned/primed both parts, applied one
of the 600
series bearing retainer compounds, screwed them together, and the
parts locked
up after 1 1/2 turns. The fit was great when I dry-threaded them...

The expiration dates in general on catalysts and curing agents should,
at the least,
be considered. The closer you are to the expiration date, the more the
need for a
test bond. If the curing agent has complicated chemistry as well, such
as in the
case of some RTVs for potting, ignore the expiration date at your
peril. Disasters
will absolutely occur. Been there....
