I have some ball bearing assemblies that need to be put together with
Loctite , will probably use Loctite No. 271 as it is available locally ,
problem is they recommend using the 7471 Cleaner Accelerator and it's very
expensive to get it shipped in and not found locally , they sometimes refer
to it as Acetone but it can't be that as the stuff is very expensive , shelf
life of these products is only a year or so , wonder if anybody has found
something that is available and cheap that will work for Cleaner /
Accelerator for Loctite.
Note that a Loctite representative who was giving a talk to our
metalworking club was asked about the shelf life, and how long it
*really* would last.
He explained that the shelf life on the products could be blamed
on the GSA (Government Supply Agency) who does all the purchasing for
the army, navy, air force, marines, and civilian branches of the
Government. They *insist* on there being an expiration date, because
their inventory system requires it. After the expiration date is
reached, large quantities are shipped back to Loctite to be re-certified
with a new expiration date. Individuals (not "blessed" with an
inventory system) are free to ignore the expiration date.
Now -- I could believe that the cleaner part might well be
acetone (though the spray can which I have does not *smell* like it) and
normally the presence of metal ions is what starts it curing. I believe
that the accelerator has some metal ions added to start it curing on
things which don't have metal ions -- such as plastics.
