What's medical grade CA? Is that $3 dimestore glue that's been

house works great for wounds.

Medical grade CA is a different formulation with somewhat more high
grade component chemicals. This shouldn't be a surprise - dimestore
grade CA doesn't perform nearly as well as even "Hot Stuff" does.

According tohttp://en.wikipedia.org/wiki/Cyanoacrylate, most regular
CA glue is methyl-2-cyanoacrylate, which degrades fairly quickly
in contact with human tissue and produces formaldehyde. Which is
a pretty strong irritant. Medical CA is 2-octyl cyanoacrylate
which degrades _much_ slower, and won't produce tissue irritation.

The FDA has only approved 2-octyl cyanoacrylate for medical use.

Shrug. I use the civilian, non-medical-rated stuff on cracked and split
fingernails, and even on the occasional paper cut, on a routine basis.
(You know, like when you get a cut beside your nail, so whenever you
stick that hand in your pocket, the cut catches, and you scream in pain?
CA works great to keep those sealed.)

For the OP original question, while at Home Depot, I found they have a
super glue made by locktite that specifically for plasitcs. I don't
know how much better or different it may be thqn std crazyt glue, but
that's what I went with. I just repaired my refrig shelf foot with
it. It cost about $3 and is a two part system. First you apply some
kind of activator to both surfaces, which goes on with a small magic
marker type device. Then you apply the glue to one surface and hold
together for 30 secs.

A lot of this depends of course on where the break is. In my case,
it's on one of the 4 feet that holds it, but it winds up with most of
the load pressing down onto the crack faces as opposed to shearing
force which would cause the crack surfaces to try to move against each
other. Hopefully it will hold, I'll let you know if it falls apart.
