Permatex 84109 PermaPoxy 4 Minute Multi-Metal Epoxy, 0.84 oz.

Good quality, easy to apply, fast-working, permanent bond, effective results, shipped fast, and reasonably priced.

Works great. Used it to bond a grade five bolt head in a tough spot with limited space. Just make sure to clean the area well, I used acetone, and this Steel Weld will do it's job. Quick set up time, so just be aware you will only have a few minutes to work with it until it begins to harden. I held my thumb on the head for five minutes and the head was appeared to be bonded quite strongly. The cap is great too, as once you snap it off, flip over to close the tube so the epoxy does not dry out. Good stuff. I am sure I will use it again...

My project was bonding aluminum plate to machined aluminum round stock to give a blunt nose to the plate. I hit all matting surfaces quickly with 36 grit on a die grinder. After grinding, I cleaned all surfaces with alcohol pads. I applied the epoxy to just the round stock using an acid brush with the bristles cut back about half way to make it stiffer, then placed the plate in top. I used a 5 lb weight during the cure time. About 24 hours later I wanted to machine the assembly on a mill. The cut started on the round stock and went into the plate. Notching the corner went as smooth as possible if they were one solid piece. I had a long notch to make but I made a mistake on my depth. During my dry run (spindle off, normally I have it on) the cutter dropped right onto the round stock right about at center and popped it right off. I was reviving my workpiece and this wasn't detrimental. Matter of fact, if it adhered more I would have lost a cutter. So, I consider this lucky. What I observed though was that all of the epoxy stayed on the round stock where I directly applied it, nothing transferred to the plate. In the future, I think wetting both surfaces will give the best bond and that is common with some adhesives but not mentioned in the directions for this one.

This product is a fantastic find! It's reasonably priced, making it accessible for most budgets without compromising on quality. The product is exactly as described, and its usefulness cannot be overstated. I've found it to be incredibly practical and efficient in meeting my needs. The attention to detail is impressive, and the performance is on par with more expensive alternatives. If you're looking for something reliable, well-made, and at a fair price point, this is the perfect choice. Highly recommended!

Exact bonding strength I needed for metal bed frame.

Purchased to epoxy brass to brass. My first and second tests were disappointing failures. Brass was cleaned and lightly sanded but the initial bonding though good the pieces were easily separated as they cured. For a 3rd test I took two different pieces of brass, cleaned, bonded and had GREAT success! Been a few weeks since and the bond is still excellent. Very strong union. I am so glad it worked. Not sure why first two tests failed

Wire frame glasses with a seperate welded bridge are defenitely a repair issue I’ll have to reluctantly rely on an eyeglass center or jeweler that has the appropriate welding equipment. These eyeglass frames were purchased new less than 6 months ago. I don’t remember sitting on them..or leaving them under the wheel of a car ….regardless…the weld broke somewhere along the rim and continued to split away from the bridge. I thought as long as I made the effort to sand the surfaces with a light Dremel disc action it would sufficiently provide a bondable surface. (Eye glass piece was removed prior to DIY attempt) I checked, double checked, and triple checked the instructions, the frame surface area, and respected the curing time. The weld actually did work. I did trade off and on with my backup glasses for the first week because I wanted to gently ease into all day usage just to be sure. I was simply laying reclined watching TV when my eyes caught the side view of the metal separating again. I had been observant and cautious the entire time and can’t recall any occurrence of rough or mishandling use. They sat way beyond the curing time positioned in my gator clip multi arm soldering station clamping everything in place. Followed by a few days of resting time out of the clamps. Either I missed some inconspicuous tiny detail in the process like a rogue airborne lint particle landing on my frames seconds before dropping the gray goo mixture on the target, or these frames are exclusive to professional welding only. I’ve not tested the permapoxy on anything else yet, but I have my sights set on some spare pieces of rebar I’m looking to form together for a window security grill. I give 3 stars thus far but may return to boost my review after pursuing other projects. I’m anxious to weld a silver dollar to the sidewalk out front and observe the next Amazon delivery driver become frustrated. Performing a prank is an ancient act of showing friendship and respect…..in some culture….somewhere….i’m pretty sure….Prime delivery people are my heroes and emotional support team, not just my personal quality testing participants.

Ok so on my UTV the brake caliper came loose and jammed into the inner wheel hard enough it cracked pretty good. The air leaked out, Fast ( pretty big crack ). So before I ordered a Tube I used this Epoxy on the wheel and it's holding air. Im really surprised this worked. Now keep in mind UTV/ ATV tires only air up to about 7 to 12 psi ( this one is at 10.5 ) so I would not try this on a car wheel or high pressure. But hey it worked great here!

Working good.

I had an issue with an old custom made handle for a shower. The original screw type attachment wasn’t able to be repaired and replacement was prohibitively expensive. This epoxy worked a charm. No need for clamping. Virtually invisible bond that so far seems to be holding up like new. Used a tiny bit and, truth be known, will probably never need the rest of the tubes but at twenty dollars way cheaper than replacing the handle mechanism

👍 🆗️

Filled a small hole in motorbike casing one thousand miles later hasn't leaked yet great product

Lo usé para cerrar una pequeña fuga de vacío en una línea de metal en el auto, al momento se desempeña muy bien, me encantaría probar la resistencia de 4500psi que promete este epóxico pero actualmente no tengo los medios para hacerlo correctamente, sin embargo parece muy resistente, el color gris en mi aplicación fue bueno se pierde en el color del metal y prácticamente no se nota a menos que lo busques con algo de minuciosidad, quizá lo use para pegar un soporte (acero) de cables que rompieron unos mecánicos en una reparación de emergencia, en resumen me parece muy recomendable este epóxico y como dice en su etiqueta, una vez mezclado, exactamente a los 5 minutos deja de ser moldeable y a los 10 ya está fijo y endurecido, así como el fraguado total sí es a las 24 horas.
