Thread: Loctite - Can I warm it up, move the joint and let it cool again?

01/01/2016 10:26:05

Hello Steve

Loctite are Anerobic Resins . This means that they cure in the Absence of Oxygen or Air. The curing process is that they change from a liquid to a solid/ plastic in the absence of air. When they are in the bottle , the Air in the bottle keeps them as a liquid. When you use Loctite to join say a wheel on to an axle , the absence of air in the small/ tiny gap between the wheel and the axle causes the Loctite to cure and it becomes a plastic. Loctite products are prone to failure due to Shock . So this means you must use a Keyway/ Key to transmit the force. Basically the different Loctite products have different strengths.

About twenty years ago I made the same mistake as your correspondent in that I Loctited a reversing lever on to a shaft in the wrong place. I tried to heat it up with no success so had to drill out the shaft and make a new shaft.
