Loctite service

I had a question I needed and answer for, the product was Henkels 'Loctite 648'  which is used to bond metal parts together.  Searching I soon found the Henkel we site based in England, time wise we are some two hours in front of them, so a sent them an email.

Mid morning and I had my reply, thats great back up service from Loctite! they even sent me the full three page data sheets.


Possibly! It is all a case of force applied against the area glued. Any joint, if you apply enough force to it can be broken.
Generally we would recommend that you apply as much heat as you can and force the bits apart whilst hot. I have attached the datasheet for Loctite 648 and if you look at the "Hot Strength" graph (on page 2) you can get a better feeling for this.

Best regards
