Green Loctite

Anyone ever use the green loctite threadlocker? It's the kind you can use on things that are already assembled. It's supposed to "creep" into the threads. Just wondered if you have to use heat to get it apart. The only kind I use is the blue because some things I don't want to burn the paint off of heating to get back apart.
 
Green sets up hard and brittle and is permanent. I thought the american version was just used as a sleeve and bearing retainer on worn shaft's? Don't like the red for the same reason.
 
My experience with green is that one should use it on things that they never, ever want to take apart again!
 
Green is generally a sleeve and bearing retainer for a cheap nasty fix on a poor fit. When used cold it's a permanent set up. If you apply a modest amount of heat tho... mabey 3-400 degrees and it turns to goo again. No problem to remove something when it's hot... but when it's cold, forget about it. Stuff gonna break.

Have to heat it to above 300* F. to get it to release. It DOES bond!We use it on shafts to set tapers and sleeves that we want to make dang sure will never move again. And it works!
 
I know if you weld up cracks in your shovelhead gas tank, and you just can't seem to get it sealed you can put green locktite on the hot metal, let it cool and the leaks will be sealed. I lasts a good long time too, even with the vibration.
 

As others have said I have used green for sleeve glue. I have some other Loctite that is for already assembled fittings, or fasteners. I want to say that it is pale yellow. So far I have used it only once or twice and it seems to work
 
You guys are talking about two differant products. OP was talking about 290 which is sold as a wicking type and yes I have used it and it works OK. The others are talking about 640 sleeve retainer, both are green.

Yes the loctite you speak of really does creep into the threads. You absolutely DO need heat to get it apart. I've used it on snowmobile clutches, where 2 parts are threaded together, and the factory uses the 290 loctite. You heat it up good with the propane torch and it melts like butter.
