I did mold repair of plastic injection, zinc, and lead molds for awhile, once. We used RED Loctite. We loosened threaded items using an oxy/acetylene brazing tip. I think it releases around 400 degrees F. but maybe it is higher. It takes a lot of heat usually. Probably release heat temp of Red is on GOOGLE somewhere.
As to acetone working on releasing stuck fingers permanently stuck to my palm using Crazy Glue >>> been there, done that! Use liberaly and it works very well, but DON'T use around open flame. I had a tube of glue leak while I was using it. Why a surgeon would use "delicate" surgery is beyond me---these guys are supposed to be highly educated! Of course liberal use of acetone on private parts might just be an attention getter!! When I use that stuff (glue) I now always have a can of acetone close by.

Loctite - how to take off? Group: rec.crafts.metalworking Date: Wed, Aug 20, 2003, 1:14pm (EDT-3) From: firstname.lastname@example.org (Martin=A0Lynch) I have to replace a bolt that was threaded and then sealed with either Loctite or some other type of sealant. Is there a special compound that I should spray on the bolt to loosen the loctite before I take the bolt out, or should I be able to jerk it loose from simply torquing it real hard? Thanks
