Extreme Epoxy

Unread postAuthor: tigerblues28 » Sat Dec 21, 2013 8:05 pm

I'm looking for a good strong epoxy. I've been using JB weld, and its all right, and I cant weld. Soldering is a possibility, but I want to use steel as a main material. Does anyone know of a good epoxy with a really high psi rating? ( above 4,000 psi)

Could I solder it?

Stainless steel too.

Do you understand the difference between a material property and a pressure rating?

Steel can be soldered if the proper flux is used.

Yes I know. JB weld had something like 3,500 lbs of strength.

And after I posted this I looked It up a lot more and I found out that it was possible. I'm assuming with a quality solder I can use a good about of pressure with it? (850 from a paintball tank?)

Good.

You'll need to calculate the lap shear failure point. Area of the joint multiplied by lap shear strength. If lap shear isn't published, use 60% of tensile strength.
