Epoxies for metal can range significantly in quality. Good options will last a long time, protecting against moisture, rust, and bacteria for the foreseeable future. However, subpar products will do none of that, costing you time and money for something that doesn’t help at all.
We tested many dozens of options to see how they last against a variety of environmental factors over a long period. In the process, we have narrowed the epoxy market down to seven reliable products.
Read on for the best options on the market.
|Gorilla Heavy Duty|
|Loctite Heavy Duty|
|PC Products Heavy Duty||32 oz.||4.35/5|
|J-B Weld 8281||10 oz.||4.10/5|
The Yanyi Epoxy Resin is the perfect product for sealing cracks and imperfections on stainless steel material. It fastens and dries quickly for near-instant results.
The material can be used even on uneven surfaces and it can even be applied to plastics and woods. If you are looking for a versatile resin that will be handy to keep in the junk drawer, this is it.
However, there are some questions about how long the sealant works. Some users say that their repairs were quickly undone. Granted, this could simply be because they did not use the product correctly. Still, it is something you will want to be aware of.
Gorilla is known for its glue products and this steel bond adhesive will do nothing but strengthen its reputation. This is an affordable package that features two highly effective tubes. The glue forms a quick and very durable bond that should provide a lasting repair.
The product can be used with ceramic, steel, wood and plastic. It’s great for a wide range of different uses but do keep in mind that it features a pretty overwhelming smell. Unfortunately, the pungent glue odor tends to stick around for some time.
Scent aside, however, it is a pretty handy tool for a wide range of applications.
The Loctite Heavy Duty Epoxy is one of the most expensive options on our list today. That said, it also gives you plenty of bang for your buck. The package comes with two four-ounce tubes, both of which are extremely powerful adhesives.
This is also one of the fastest drying units on our list. The adhesive dries in just five minutes, which guarantees that it will seal very sturdily.
Last but not least, Loctite works well with materials ranging from metal, wood, fiberglass, leather, plastic, plaster, and metal. In other words, it is just as versatile as any other product on our list and more durable than most.
If you are willing to pay a little bit more for his product you will enjoy high-quality results.
The PC-7 can be used with wood, fiberglass, metal, plaster, plastics, and ceramic. It is appropriate for both indoors and out and it creates a quick and durable seal. In theory, you can reuse the item that you’ve repaired soon after applying the solution.
The adhesive is rated to withstand a moderate range of temperatures. The manufacturer claims that it will work in environments between 35-115 degrees. Outside of this range, there is no certainty that the adhesive will work.
The packaging also claims that it is good for sealing cracks and filling gaps. Unfortunately, we have found that the extent to which this is true is fairly limited.
However, as a general adhesive, the PC Products is highly effective.
The J-B Weld is one of the pricier epoxies that are on our list today. It is a fairly versatile adhesive that applies not just to stainless steel abut also to woods, ceramic, plastic, and plastic.
The adhesive sets in relatively quickly, with objects being ready to handle after just eight hours or so. Once the adhesive has dried, it may be sustainable at temperatures of up to 550 degrees, making it great for a wide range of applications.
We have found that the binding agent is surprisingly runny. This can make it fairly difficult to apply. It also makes it more challenging for the adhesive to set properly.
The PC Products features a stick style applicator that you rub onto the surface that you are trying to repair.
This is an extremely fast-acting adhesive that dries in just sixty minutes. The stated purpose is for automotive repairs but the truth is that it will work with a wide range of different metals and surfaces.
The adhesive features a pretty impressive temperature range of between -25 to 250 degrees, which means it should work well in pretty much any situation.
Unfortunately, the adhesive is somewhat difficult to work with. It sticks to everything and is challenging to sand down, which means some people might have a hard time working with it.
We end the list with a “jack of all trades, master of none” pick. This glue is compatible with leather, ceramic, wood, plaster, fiberglass, metal, and plastic. You name it, this glue will be able to work with it.
However, the extent to which it is effective is also regrettably limited. The bond is not very strong, it takes a long time to set in, it is generally difficult to work with, and it leaves behind an extremely pungent odor. For very light work it may be suitable; but otherwise, you will want to invest in something a little bit more reliable.
Here are some buying considerations that will help you choose the perfect epoxy for your needs.
The dry time will help to determine how quickly you can use the item that you repaired. Dry times can range from one to many hours. Naturally, the faster your item dries, the sooner you will be able to use it. Fast-drying glues also often set better because there is less time for something to disturb them.
The value of a steel epoxy is determined mostly by the quantity of the solution. For example, an eight-ounce tube will probably cost more than a four-ounce tube, but there is a decent chance that you will be less per ounce when you choose bigger packages.
Of course, metal epoxy is never terribly expensive but everyone likes a good deal, right?
Not every product can work with every material. Of course, the purpose of today’s guide is to identify good metal adhesives. However, once you have repaired your metal-based item, chances are fairly good that there will still be some epoxy leftover in the tube.
That being the case, it will probably be more worth your money to invest in something that can be used on other surfaces as well. For example, it is not uncommon for a metal-epoxy to also be compatible with wood, ceramic, concrete, or even plastic.
All adhesives are impacted by temperature. Fortunately, most normal temperatures will be perfectly appropriate for the product that you buy. However, when you get into extremely hot or extremely cold climates, you may begin to run into problems.
It is fairly common to find the temperature range for an adhesive to be somewhere between 35-100 degrees. However, if you live in a more extreme environment with uncommonly high or low temperatures you may need to look into a specialty product.
Similarly, it is never a very good idea to use an adhesive in the middle of winter or summer—especially on things that are destined to spend time outside.
Once the sealant has dried, it is subject to an entirely different range of temperatures. Most adhesives will be quite durable, able to withstand temperatures of several hundred degrees. However, the limitations can be quite a bit more restrictive than that in other cases.
If the item that you are repairing is often subject to unusually high temperatures, you will want to pay attention to this range.
Not every adhesive can be used outdoors. If you are repairing something that is to spend time outside you will want to make sure the adhesive has been fortified against the elements. Generally speaking, the company will advertise where the product can be used on the box.
However, if there is any uncertainty, it may be in your interest to reach out to the manufacturer for clarification before you finalize a purchase.
To repair something is one thing. To seal it is entirely different. If you are repairing a pipe or something else that comes into contact with lots of moisture, you will need to make sure that the glue is up for that task.
Epoxy that is to be used for plumbing will need to be resistant to moisture. Naturally, it will also need to be extremely durable.
Epoxies that are appropriate for masonry and plumbing will advertise these features on their package. However, it is useful to further investigate the effectiveness of the product before you apply it to your plumbing.
Reviews just like the ones above are great for determining the effectiveness of a sealant.
When you get right down to it, metal epoxy is just glorified glue. It tends to be stronger but otherwise, the impact is exactly the same. That being the case, it is applied almost the same way as glue as well.
Most of the units on our list today squeeze out of a tube. However, there are also “stick” style applicators. With these units, you rub the adhesive directly onto the surface.
Neither is necessarily better than the other. The stick may be a little bit easier to handle, but it struggles to access deeper cracks. Ultimately, you just need to find the solution that works best for you.
With our epoxy for metal reviews now done, all that you have left to do is to finalize your buying decision. Did you like the reliable quality of our top choice, the Yanyi 90856575 Epoxy Resin?
Or maybe you preferred the high level of value that comes with our runner-up choice, the Gorilla 433010 Heavy Duty Steel Bond 2-Part Epoxy.
Of course, the truth is that there are lots of good options on our list today, so anything you go with will work well!
