## Description

Permatex Steel Weld Epoxy is a versatile, easy-to-use, multi-metal epoxy two-part adhesive and filler system that eliminates the need for welding or brazing. Sets in four minutes, no clamping needed. Dark grey appearance. Fills gaps and will not shrink. When cured, can be drilled, sanded, threaded or filed. Resistant to water and solvents. Temperature range -60°F to 300°F (-51°C to 149°C). Permanent strength up to 4500 PSI. Ideal for use on complex, multi-piece assemblies and for bonding rigid materials, sealing welded seams, filling metal cracks, and mounting metal components.

Review: Permanent Bond - Good quality, easy to apply, fast-working, permanent bond, effective results, shipped fast, and reasonably priced.
Review: Bond is strong, just make sure to clean the work area - 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...

## Questions & Answers

**Q: Does this epoxy do well in heat? Specifically exhaust/muffler heat?**
A: I used to heat to remove the epoxy when it didn't hold as well as I had hoped. I don't think this would work with a muffler.

**Q: What material would be best to mix this on?**
A: I use piece of cardboard. It works, though it’s a pain mixing it. Make sure u mix it well.

**Q: will this fill pinholes in welding? I am looking for a product that will easily fill the little pinholes and look (and react) a lot like the steel**
A: Great question. I think it could fill the pinholes, but am unsure if it will look like the steel. You may try painting over with matched color.

**Q: Can it be used for a/c aluminum coils repair with 410A refrigerant?**
A: No, It really doesn't work ona lot of items.  We tried.

### ⭐⭐⭐⭐ How strong is it? Perfect Strength!
*by C***8 on September 20, 2020*

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.
