2. Permatex 89 PermaPoxy Multi-Metal Epoxy – Best Value
If you are looking for the best epoxy for metals for the money, you will be interested in the Permatex 84109 PermaPoxy Multi-Metal Epoxy. This product is super strong, versatile for a variety of metal purposes, and budget-friendly, which is why we have named it our best value pick.

The only reason why this product is listed number two, as opposed to number one, is because it is only suitable for metal materials, whereas our top pick was suitable for metals and non-metals alike.
3. Loctite Heavy Duty Epoxy – Premium Choice
If you are looking for a premium epoxy for metals, you should check out the Loctite 1265736-6 Heavy Duty Epoxy. Although this product is more expensive than others on this list, it is heavy-duty, resilient, and multi-purpose, making it worth its price.
Notably, the Loctite 1265736-6 is multi-purpose. It can be used as an adhesive for tile, wood, metal, ceramic, and glass. It can also be used for filling, surface repairs, and laminating. This makes this product highly useful for a variety of purposes.

It is highly resilient and is resistant to humidity, water, and most common solvents. It also has a high impact resistance so that it can be sanded, drilled, and painted. However, it does not have a long shelf life, so you may find yourself needing to purchase it more than once before it’s all gone.
4. Yanyi 13 Epoxy Putty Stick
Another great epoxy for metals to check out is the Yanyi 13 Epoxy Putty Stick. This product is multi-purpose, easy to use, and budget-friendly. It is suitable for most small- to medium-sized projects, but it is not ideal for large projects.
The Yanyi 13 is multi-purpose in that it bonds to a range of materials. It can bond to metal, wood, glass, ceramic, fiberglass, stone, marble, and many rigid plastics. This allows it to be useful for a variety of purposes, such as fixing leaks and tanks, repairing appliances, fixing toys, and filling cracks in concrete.
Additionally, the Yanyi 13 is extremely easy to use. All you need to do is cut and hand knead until the color becomes uniform, and apply it to the damaged area. It only takes about 10 minutes to knead and use, also making it fast and efficient. This one also suffers from a short shelf life though, so be mindful of this before buying in bulk.
5. J-B Weld Professional Size Steel Reinforced Epoxy
J-B Weld is a leading manufacturer of top epoxies, making it no surprise that the J-B Weld 8281 Professional Size Steel Reinforced Epoxy is on this list. This product is highly versatile, dependable, and easy to use.

Additionally, this J-B Weld product is highly dependable and strong. It has a tensile strength of 5,020 PSI and can withstand up to 550 degrees Fahrenheit. Once fully cured, it is waterproof and resistant to petroleum, chemical, and acid. However, it does require the purchase of some additional accessories in order to use it, which is slightly annoying, especially given that it’s not cheap.
6. Gorilla Heavy Duty GorillaWeld Steel Bond
Another good epoxy for metals on our list is the Gorilla Heavy Duty GorillaWeld Steel Bond. This product is incredibly strong, easy to use, and convenient for both metals and non-metals. This makes it a great choice for small and medium DIY projects.
Importantly, the Gorilla Heavy Duty GorillaWeld Steel Bond is incredibly strong. Once dried, it has a strength rating of up to 4,250 PSI. This allows it to be suitable for a variety of purposes. More so, it is suitable for a variety of materials, including metal, some plastics, concrete, ceramics, PVC, fiberglass, and more.
Additionally, the Gorilla Heavy Duty GorillaWeld Steel Bond is easy to use and has a 10 minute set time. This allows you enough time to adjust or reposition anything after the epoxy has been placed, making it great for beginners who are not familiar with epoxy yet. Watch out though, it has a very strong smell. What’s more, it’s not suitable for high heat.
7. PASCOFIX Strongest Super Epoxy
If you are looking for an all-purpose epoxy, then you will be interested in the PASCOFIX Strongest Super Epoxy. This product is very strong, bonds quickly, and has a long shelf life if kept in the freezer. It is extremely simple and easy to use, making it perfect for experienced users or beginners alike.

But it’s not without its downfalls. Firstly, the bottle it comes in is poorly constructed, which can impact the work you do. Secondly, it has a very short setting time, so you have to move quickly and most likely be experienced in using epoxy to go with this product. Thirdly, it’s not suitable for heavy-duty jobs.
8. Jenolite 112gm Steel Repair Epoxy
The next epoxy for metals on our list is the Jenolite 112gm Steel Repair Epoxy. This product is very strong and suitable for anything made of metal, but it is not suitable for non-metal materials.
Notably, the Jenolite 112gm is great for metal materials because it is non-rusting and steel reinforced. It quickly repairs or rebuilds anything made of metal. It is even strong enough that it can be drilled, machined, ground, and painted once fully cured.
With that being said, there are some downsides to this Jenolite product. Most notably, it is not suitable for anything other than metal. It is especially not suitable for plastics. Additionally, it is difficult to knead, making it hard for those who are inexperienced at kneading epoxy. It’s also not very attractive looking once dried.
9. PC Products 25550 PC-Metal Epoxy Putty

Unfortunately, the PC Products 25550 is not very heavy-duty, and it is not suitable for any non-metal material. Instead, this product will only be suitable for small jobs, such as filling holes.
10. Pratley 2 Part Epoxy Plastic Adhesive
Finally, the last product on our list is the Pratley 2 Part Epoxy Plastic Adhesive. This product is highly affordable, and it is suitable for a variety of materials such as rigid plastic, metal, and ceramics. Unfortunately, this is all the positives we can say about this product because it has more cons than pros.
The Pratley 2 Part Epoxy Plastic Adhesive is not strong in comparison to other epoxies. As a result, it is not suitable for most jobs involving metal. It is also not suitable for other jobs, such as fixing rubber shoes. In fact, this epoxy is about as strong as regular super glue.
If you are still unsure which product to choose, read on. Here is a buyer’s guide that lists the most important factors to consider when selecting epoxy for metals. These aspects will help you to determine which product is best for your needs when it comes to picking an epoxy for metals.
The most important factor to consider when selecting an epoxy is compatibility. Not all products are suitable to work with every material. As a result, you need to select a product that is compatible with the materials you intend to use.
For example, make sure that the epoxy is suitable for metals if you plan in on that surface. In contrast, if you plan to use epoxy for a variety of purposes, make sure to get a multi-purpose epoxy.
Another important factor to consider when purchasing an epoxy for metal is its strength factor. The strength will determine how well the epoxy bonds to the material. More so, the strength will also determine the material’s water or solvent resistance, as well as its impact resistance. If you need epoxy for heavy-duty purposes, make sure that it has a high PSI rating.
3. Temperature Rating
A factor related to strength is the temperature rating. Once the material has dried, it will be subject to different ranges of temperatures. If you plan to use the epoxy in a setting with high temperatures, such as on an automotive, make sure that the epoxy is suitable for the intended temperature range. If the epoxy has a low temperature rating, it will not hold under high temperatures.
4. Sealant Capabilities
Sealant capability is another factor to consider when purchasing epoxy. Epoxies that are only designed for repairs will not seal the material. If you are repairing items, such as a pipe, that come in contact with moisture, you need to make sure that your epoxy is also sealant. This will ensure that the epoxy is durable even in the case of water.
If you plan to use the epoxy for masonry or plumbing, you especially need to make sure that your epoxy has sealant capabilities. If not, your epoxy will be unhelpful and short-lived for your purposes.
5. Set Time
Additionally, you need to consider the set time when purchasing an epoxy. Since epoxies dry extremely hard, you only have a limited window to adjust or change the positioning once the epoxy has been set. The set time will tell you how long you have to readjust your items.
If you know that you will need a longer time to adjust, select products that have a longer set time. The longer the set time, the longer it will take for the epoxy to harden completely, however.
6. Applicator Style
Finally, the last factor to consider is the applicator style. Today, there are many applicator styles to choose from. Most products are 2-part systems that you will pour into a disposable cup or bowl and combine with a disposable stirring agent. This applicator style tends to be the most durable, but it is messier and requires additional items.
Other applicators styles include sticks that you rub onto a surface or a putty that you stick on to the surface. These products are more suitable for easy jobs and easy cleanup. With that being said, they are normally not suitable for heavy-duty jobs.
After considering all of our reviews and buyer’s guide, we recommend the PC Products 167779 PC-7 Multi-purpose Epoxy. It is compatible with metal as well as other materials. At the same time, it is highly strong, is suitable for repairing and sealing, and has a flexible set time.
If you are looking for a product on a budget, however, we recommend the Permatex 84109 PermaPoxy Multi-Metal Epoxy. Like our top pick, this product is strong, suitable for a variety of purposes, and has good sealant capabilities. The main downside is that it is only compatible with metals, not non-metals.
We hope that this article has helped you select the best epoxy for metals or at least provided you with guidance on how to select a product for your needs.
