The Ultimate Epoxy Competition--Which Epoxy is the Best?

Jun 01, 2021
If you're like me, you're always wondering

which

product is the

best

,

which

product provides the most strength when it comes to glues and it can be quite frustrating taking the time to glue something and usually having to wait for it to stick. dry for a while. one or two days and then after waiting all that time it fails, that's extremely frustrating and plus you've wasted money so there's probably a waste of money as you've experienced tens of millions of dollars being spent every year on different types of glues and epoxies, obviously I don't have time to try each of these, but I selected some of the

best

brands out there and today we will find out once and for all which of these glues. are the best, the products I will be trying include JB Weld extreme heat, fast solder, original formula, Devcon, plastic, steel, Loctite in gorilla, so if you are trying to find out which

epoxy

is the best, you might want to Watch today's video, one of the most critical steps whenever you try to use glue or

epoxy

is surface preparation.

If you don't prepare the surface properly, it's unrealistic to expect the epoxy to stick, so the first thing I'm going to do is get to work. with this old rusty piece of angle iron and I'm going to remove all this rust and have a very clean surface for the test so I'm going to use some 4 inch bolts they're all new and to make sure the surface has something to go by I'm going Go ahead and sand the end of this bolt, each one will be sanded before testing. I'm not going to touch the area that was sanded because I don't want anything.

There is some sort of oil residue on the bolt. Some have commented that JB quick solder is not as strong as the original formula, so I am very interested to know which of these is stronger. I'll get at least two, maybe three different ones. Types of tests today. I have three different opportunities to test the strength of these epoxies and I really wanted to do just two, but I made a third in case I make a mistake. The first two that I want to execute. sure it includes first the downward force, the gravitational force and I have the weight of 2 and 1 of 12 pounds up to the weight of 25 pounds.

The second type of test is the twisting movement and for that I have a torque wrench that is used in inches. inch-pounds this ranges from zero to 200 inch-pounds. I have a much larger torque wrench. If we need to go to foot-pounds, we'll soon find out what we need to do, so the first thing we'll do is use these sets of weights. to determine which epoxy is the strongest for downward force, so the first test I will do is the downward test, as you can see, I have two nuts here that are already on this bolt, the first nut is all the way. inward, as far away as possible, the second one is about 1/4 inch out, so what I'm going to do is apply the weight precisely between these two nuts to make sure that on each of these bolts the force down is applied at exactly the same distance from the base to the same point because when it comes to physics, every little detail makes a big difference as to how much torque is applied at the end of this and it's simply not a fair test if I'm off by even an eighth of an inch the second test I'm going to do is the torque so you can see I have two nuts on this bolt and as I turn it it's going to release at some point and the third bolt is at in case you screw up one of these two tests.

I have another test in mind, but I won't even use it if I don't pass these first two tests correctly. The first test. I'll be running, it includes using 2 and 2 pounds and this chain probably weighs maybe half a pound and I'll apply the weight for about 10 seconds. First up is JB Weld, the extreme heat was good. I can't stand it at all, that's extremely weak. Got it right at 10lbs, ok, JB quick weld just failed. 122 lbs up first is the original JB Weld, okay, now I'm up to 15 lbs, now 17 1/2 lbs, okay, we're up to 20 lbs okay, 22 and 2 lbs okay, next up is 25 lbs 272 pounds, so we'll go through each of these real quick and talk about what happened, the extreme heat of the first one.
All I can say is that it doesn't seem like the Extreme Heat has very good adhesive properties. This Stu is very hard and brittle, as you can see, it just breaks, it's almost like a kind of concrete Mor. It's very, very, just a hard surface that doesn't seem to stick very well. One thing I have noticed about these quick epoxies is that they do not adhere to the surface, as you can see there is bare steel and this steel was very coarsely ground. I mean, this, the epoxy should really bond well with this, but none of the fast epoxies even did a very good job bonding with the material.
JB Weld won this

competition

and the interesting thing about JB Weld, as you can see, it stuck very well to the material to the surface that we were trying to have this bolt. adhere and that's the key, epoxies like Devcon and JB Weld because they take time to dry, they seem to have done a much better job of adhering to the steel compared to the fast epoxies. Really I can not. There is a big difference between Loctite and JB's quick solder. They both did exactly the same thing, they just didn't stick to the steel. Agreed, Devcon, much like JB, did an excellent job of adhering both the bolt and the In fact, as you see, there isn't much exposed steel, what you see are traces of epoxy everywhere and what that means is that the epoxy is releasing from itself and not from the steel.
This is exactly the best case scenario. You want the epoxy to have the strength to stick to the two pieces of steel you're trying to join together, so Gorilla actually did a better job than I thought. For a quick drying epoxy, it worked well, as you can see. It didn't stick to the steel, it came loose and like the other two fast epoxies, the problem is that it just doesn't have the sticking power to the steel. I'm glad I went ahead and put in three bolts because I accidentally hit This JB Weld is extremely hot and I barely hit it and it came loose so I'm going to use an inch pound torque wrench and I have this set at 5 inches of torque so which is a very low torque setting at this time.
None of these epoxies should fail at 5 in. lbs. We'll see how this one goes. It just failed, it just broke. I didn't even get 5 inbs of torque, 100 inbs. Okay, the JB quick solder failed at 100 inbs and as you can see they just didn't stick to the metal, these quick epoxies just can't seem to stick to any surface you try to get them to stick to. This was a very clean surface, no oily substances, regular 24 hour epoxies. they are doing a very good job joining this steel, okay we are at 105, okay, it failed at 120, 125 inch pounds, okay JB, it just failed at 185 inches, PBS 200 INB, so what I find interesting is how JB Weld failed compared to Devcon.
Devcon proved to be a little bit stronger, but in the torque test, if you notice JB Weld just did it, it looked like it went around the bolt and JB Weld is a little bit more flexible or a little bit more flexible. On the other hand, Devcon, more flexible, is very, very fragile, it is a very hard plastic and this is not necessarily a bad thing, it just depends on the application. Well, next test we will only test the original Loctite Devcon from JB Weld and, unfortunately, the gorilla. the JB quick weld came loose and the bolt I would have used to test this, but to me it doesn't really matter.
The CU JB quick weld has not proven to be as competitive as the others left, but what we are going to do is simply measure the ability of these epoxies to absorb pure impact, the impact of dropping a weight, so which will basically be a 1 and 4 inch drop. Well, JB didn't take the pressure he can. Well, people are spending tens of millions of dollars on these epoxies every year and I hope the testing I did today helps inform you which epoxy is best for your specific application and that's the key. vary depending on what you're trying to do, you might need something that dries quickly or is super strong or maybe even something that's a little more flexible, so it depends, there's no clear winner in this test on terms You know it depends on what you're trying to use the epoxies for?
All that being said, is there a better epoxy I could have tried? I'd love to hear your feedback on it, finally, if I've done a good job. In this video I hope you will consider giving me the thumbs up. I work very hard at this and spend a lot of time editing videos and a lot of expense putting them together.
