Best Metal Epoxy Buying Guides

We use glues or epoxies to solve a problem. Solving requires time. And in today’s world, time’s the most valuable asset out there. So, most of us would hate to return to the problem again and again.

For that reason, we believe it’s important to know how to choose the best metal bonding epoxy. To ease your hassle, we’ve prepared a thorough guide here. Just follow these points while you look for epoxies-

Bond Strength and Durability

We’re mentioning this because here we’re talking about bonding metals. So, if it’s a tool that you’re fixing, you must make sure that it doesn’t break while working.

Our advice here is that look at the tensile strength of the epoxy before buying it. Anything above 1000 PSI should be enough for regular jobs. For temporary bonds and filling purposes, 800+ PSI would be sufficient. However, if you’re planning to use it on a tool or something like that, then go for 2000+ PSI.

That’s not all-

You might want to check if the epoxy would be okay with sanding, drilling, etc. after touches. We included this feature here because it’s related with strength.

Dry Time

If the epoxy is selling in the market then it works. Once you’ve decided on the bond PSI rating, it’s time to look at the dry time.

In our list we’ve seen different sets of times. Let’s make it simple for you-

Category 1: Takes more than an hour to set. However, these tend to give the strongest bond quality.

Category 2: Has a setting time range of 4 – 10 minutes. However, there’s more in this category. Some of these epoxies have a long cure time while some have short cure time. Some epoxies in here will take at best 1 hour to cure. While some will take 24 hours to cure.   

Category 3: These are the fastest ones out there. These can set within a minute. So, if you want to keep something for emergencies, keep one of these with you.

However, we’ve seen another trend at play here. Some quick curing epoxies tend to give weaker bonds. And because of that reason we’ve asked you to set on the strength at first.

Here our advice would be finding the one that gives the strongest bond within the least cure time. That would be to find the best epoxy glue for metal that cures within an hour.

Value

By value we mean the amount considering the price range. Look at the amount of epoxy you’re getting for the money. Calculate how much per ounce is costing you. Take the one that gives you the highest amount for the money.

However, there’s something that you should keep in mind there. The more features your epoxy covers, the more it’ll cost to you. That’s why we’ve kept it at third. First set on more important factors, then decide on this.

Temperature Range

It’s important to know the temperature range of the epoxy. There are two reasons behind this suggestion of ours.

First you should know about the heat resistance of the cured epoxy. The best high heat metal epoxy will allow you to work even on the engines.

On the other hand, during winter temperatures drop drastically in some places. Make sure that your epoxy won’t crack during winter.

Indoor or Outdoor

Most of the epoxies in here are okay with harsh weather. But still make sure that your epoxy will be okay under rain and hot summer sun.

Compatibility

Although most of the epoxies here can bond different types of metals but still take a look before you buy.

You won’t use the epoxy on only metal all the time. Sometimes, it’s going to be plastic, sometimes wood. So, make sure that your epoxy is compatible on multiple surfaces.

Sealant

For this you have to find the best epoxy metal filler. Not all the epoxies can serve the role of a sealant. Moreover, you can go one step further and check if it’s non toxic to water.

Applicator Style

We’re down to the last checkbox. Once you’ve got everything figured out, decide what type of applicator would you like to use.

Although we believe after sorting through all those categories you won’t have many choices left. But still think about it. Some epoxies come in a syringe applicator while some arrive in tubes.

For the tube ones you’ll need a separate tray to mix 2 parts. Also, some epoxies come with a resealable cap. Basically look out for unique features.

However, if you’re into putty, then the case is totally different. For putties the only applicator is your hand.
