curing time
 

How long does it take for red locktite and JB weld to cure? Once cured (dried) which one holds up to oil, high temps and presure better?

They are completely differentt products, Red loctite is for threads while JB weld has a variety of uses. The red loctite is watery and sets up rather quickly with exposure to air and then hardens a bit more over time. JB weld is more like an epoxy, it can be applied thick and used like a glue. After mixing it gets gooey until it is unworkable in about 15-20 minutes.

I think he meant to say " sets up rather quickly when not exposed to air". Loctite thread locker hardens in the absence of air.

If that is true how would you ever get it out of the tube?

I have a loctite "catalog" and it doesn't say that thread locker is anaerobic but I did a search and found the following:

From Loctite page
Q: Why isn't the container full of threadlocker?
A: The containers are filled halfway because air is needed in the package to prevent the Anaerobics from solidifying.

"LOCTITE® Product 242 is a single component anaerobic
threadlocking material, which is thixotropic and develops
medium strength. The product cures when confined in the
absence of air between close fitting metal surfaces and is
particularly suitable for less active substrates such as stainless
steel and plated surfaces."

Interesting, I need a chemisty book to explain how that works!

Funny, that's like saying, which gets me to work better, a car or an airplane.

Two completely different products, with completely different applications...
