Heat to about 150 deg C and most Loctite type sealers break down

It should be mentioned that it doesn't just "go away" at that
temperature. It starts to soften, then decompose. Remove the locked
item as SOON as the material softens.

If you wait too long, the decomposition products become hard, and will
"re-glue" the lock.

I use replacable tips on several pyrotechnic punches and presses. They
wear fast, and machining new press pins is labor intensive. Tips take
but a few minutes to make.

I LocTite them in place (med-strength blue). When time to replace, I
chuck up the main pin, clamp a pair of locking pliers on the tip, then
heat with a torch until it moves. I then turn the chuck to briskly
unscrew the tip before the mass cools or the loctite decomposes
completely. Clean the residues with methylene chloride, or a long soak
in acetone followed by brushing.
