They come out because the Loctite cement is one of the Florine activated Crystaline bonding agents....
Because of the Crystaline structure these cements are very strong and resistant to rather large sheer loads, HOWEVER a sudden small shock applied to the bonded parts sends a "Shock Wave" radiating through the parts which shatters the Crystaline bond structure releasing the bonded parts.... <img border="0" alt="[ouch]" title="" src="graemlins/c.gif" />
The Loctite formula is one of the more shock tolerant agents, but still not impervious to Shock....
Its a shame that the fireing of the weapon is a shock generating action.
Another problem sometime results when the bonded parts are ferrous metals, rust in the joint resulting from the release of Florine gas which is the catalytic agent in the bonding agent.
This gas is released in excess quanities to assure complete chemical reduction of the liquid to a crystaline form.
The excess florine attacks the surrounding steel or iron....
My Observations.
