JB Weld 50112 – Best Epoxy for Plastic
The goal of using an epoxy is to get that plastic back to work. Now, if this takes around 24 hours, then it’s quite a loss for some people. So, J-B Weld just like always came to the rescue here.

We’ll uncover more about the J-B Weld 50112 ClearWeld Quick-Setting Epoxy in the next part here-
Features and Benefits:

Features and Benefits:
- Quick Setting Epoxy: This one got our title of the best quick setter. Now you might think that there are other epoxies that set in 5 minutes. But why is this one the best? Well, it’s because the gorilla epoxy gives you plenty of time to set the pieces even though it sets within 5 minutes.
- Standard Strength and Durability: The gorilla epoxy achieves a tensile strength of 2600 PSI after curing. Moreover, the syringe dispenser allows you to dispense from the two tubes at the same time.

However, the price quality ratio here seems a bit off. So, this could be your premium epoxy as well.
This epoxy is down here at number 3 because of its higher setting time and lower tensile strength. It sets at 20 minutes and creates a 3450 PSI bond.
Features and Benefits:
- Versatility at Its Best: Most of the epoxy brands claim that their epoxy works on a number of materials. However, when it comes to plastics many of them fail to keep up the reputation. In this case, you can totally trust on the Plastic Bonder. It bonds ABS, polycarbonate, Acrylic, Mylar, nylon, PVC, and even stainless steel.

Yanyi Glue Putty Stick – Best Plastic Epoxy Putty
It’s the first epoxy putty in our list here. And it has earned this position with its amazing features. If you haven’t used one before then let’s clear out the air first.
So, here’s the thing- you have to knead these in your hand before applying to the plastic. You’ll just need to add some water to smooth it up. This makes it super easy to use. If you have shaky hands then this one would be perfect for you.
Within 40 minutes of applying, the epoxy will set and in 24 hours it’ll be cured. The best part is that you’d be surprised at the bonding strength and all.
However, it’s not the end here. The Yanyi Moldable Epoxy Glue Putty Stick has some other mentionable features too-
Features and Benefits:

JB Weld 8237 – Best Strongest Plastic Epoxy Putty
With the PlasticWeld, J-B Weld captured the market of putty lovers. It’s true that putty has its separate fanbase with the easy to use feature. But J-B Weld has brought some other exciting features onto it.
Actually it was tough competition to choose the best plastic epoxy putty. But our J-B Weld 8237 PlasticWeld Plastic Repair Epoxy Putty fell behind because of popularity and versatility.
However, it’s still the strongest epoxy putty for plastics out there. Also, it’s got some out of the box features too. For example, a heat resistance of 250°F makes it okay for food containers. Now, let’s go through those features-
Features and Benefits:
- Epoxy putty of 600 PSI Shear Strength: The norm is that epoxy putties will have a lower PSI rating. Moreover, this putty is designed to bond plastics. So, it was okay if J-B Weld cut a slack in the strength corner. But they’ve brought in some muscle with this putty. The best part is that you can sand, saw, drill, file, carve, and even paint the cured bond. Long story short, this is the unique feature of this one.
- Water Safe: J-B Weld took the liberty to certify PlasticWeld from NSF. So, you can use it in your water without any hesitation. Moreover, using it in the boats won’t create any environmental issues too. Just make sure it goes through a proper curing period.
- Impact resistant.
- Easy to use just like any other epoxy putty.
- NSF certified for being safe with portable water.
- Fast curing time allows handling within 3 hours.
- The bond is semi flexible even after curing.
- Doesn’t even bond with any metal.
- Off- white cure color might require recoloring.
Permatex 84145 – Best Epoxy Filler for Plastic
This product here is the average kid of the school. Everything’s good about this epoxy but nothing’s the best here. But we believe every product has some unique feature and Permapoxy has one too. We’ll discuss that briefly in the next section.
Now, let’s get a basic overview of Permatex 84145 Permapoxy Black Plastic Weld.
Well, this Black Plastic Weld is a fast bonding epoxy. Moreover, this one’s made while keeping the plastics on focus. Permapoxy has three main mentionable features – the gap filling capability, strength and fast curing.
Let’s dive deeper with the features-
Features and Benefits:
- Quick Curing Yet Standard Strength: Our epoxy here sets in 5 minutes and cures within 10 minutes. That’s actually impressive. Normally plastic bonders take a bit of time to cure properly but Permapoxy has outdone itself in this area.
- Gap Filling at Its Best: Our plastic epoxy here fills gaps to 0.125 inches or in other words to 1/8 inches. This means that now you won’t have trouble fixing those small cracks on your plastic. However, you might need to smoothen up that crack after applying Permapoxy. But it’ll stick there without any doubt. And because of this reason it’s the unique feature of Permapoxy Black Plastic Weld.
- Syringe container results in an equal dispense.
- The bond is water resistant.
- Fills gap to 0.125 inches.
- Cured bond is adaptable to both hot and cold temperatures.
- It can resist a good number of chemicals.
- Terrifying odor makes it difficult to use indoors.
- Black cure color might need recoloring.
BSI 202 – Best Flexible Plastic Epoxy
We all want some flexibility at some point in our life. Well, we don’t know about life but if you want to make a flexible plastic bond then this is the thing you need.
This super quick epoxy isn’t quite popular but it has its reasons. Basically, in regular times plastic epoxy demand is a bit lower than the other types. Next, this epoxy cures into a special kind of bond that’s targeted to a very niche market.
However, it’s a nice epoxy for plastics overall. Let’s take a quick glance at the other features of this BSI-202 Quick-Cure 5Min Epoxy Bob Smith Ind-
Features and Benefits:
- Flexible Bond for Stressed Objects: BSI figured that not everyone needs a stiff bond. Moreover, sometimes plastic objects need flexibility to absorb shocks. So, if you use regular epoxies in those places, the object loses its effectiveness. Our epoxy here solves this exact problem by giving a flexible bond even after curing.
- Higher Container Capacity: Our epoxy here has the highest container capacity in this list. So, what does it mean for the regular users? Well, it means that if you store it properly then you won’t have to buy epoxies in a while. Basically, you’ll get a longer shelf life.
- Cures fast.
- Reaches handling strength within 15 minutes.
- Dries transparent (not totally clear).
- Can use other materials as reinforcers.
- Has the highest shelf life.
- Can’t hold strength in long term water exposure.
- Has a bad smell.
Super Glue 15277 – Best Strongest Plastic Epoxy
When it comes to pure strength the Super Glue company has outpaced others from this list. However, even after this staggering strength rating, out epoxy is at the number 7 here. So, why’s that? Well, even after the outstanding strength, our glue falls behind in a few areas.
In short, ease of use, gap filling ability, and solvent resistance are somewhat must for an epoxy to top this list. Now, let’s look at the features of Super Glue Plastic Fusion Epoxy Adhesive-
Features and Benefits:
- Super Strong: 4000 PSI actually falls in the ‘above average’ category of some regular epoxies. So, when we saw the number we were a bit surprised. This means once the glue sets down, you’ll be tension free. You can then sand, file, drill and tap the bond as you need. However, to get it right you have to mix the fluids properly.
- Quick Handling Time: Even with this strong bond, our epoxy doesn’t take much time to set. Within 30 minutes you’ll be able to handle your plastic. Which means your target object can get back to work even more quickly. However, it’ll take some more time for the bond to reach its full strength. But the handling strength is pretty good too. Just don’t apply pressure on it.
- Cures to a strong bond of 4000 PSI.
- Has a syringe based equal dispense system.
- Is designed specially to bond polymers.
- Can handle both hot and cold temperatures.
- Bond reaches handling strength in 30 Minutes.
- Has the most extreme fume in this list.
- Needs a few attempts to make it work.
Devcon 62345 – Best Steel to Plastic Epoxy
This devcon plastic epoxy is unfortunately at the lower end of this list. However, one of the major reasons for that is long curing time. Other than that, this epoxy tries to give a fight to the toppers but fails in the end. But to us this is the best epoxy for plastic to metal.
But you can still try out this ‘2500 PSI bonding epoxy’ because it’s got some unique perks of its own. The thing is not many plastic bonding epoxies can bond metals. Devcon targeted this specific market and tried to bring the best product for this market. And we’ve to agree that they’re successful.
To be more specific, Devcon 62345 Plastic Steel Epoxy has gained some popularity because of its effectiveness in rifle bedding.
So, let’s take a deeper look at the features-
Features and Benefits:
- Contains a Rust Resistant Steel Alloy: Sometimes we end up bonding plastic with metals. The bond however, starts catching humidity just after setting. With time this results in rust. Ultimately, you end either replacing the metal or using another epoxy to fix it. Now this isn’t the story of all the epoxies. We’re just saying that our epoxy here prevents rusts. Ultimately you end up saving money.
- Non-Flammable: Accidents can happen. Your house might get on fire or your kid might bring fire to your plastic epoxy. Now, some of the plastic epoxies tend to be flammable. And you know the consequences of this. As a solution to your worries, devcon introduced this plastic steel epoxy.

The Ultimate Buying Guide
We have given all the features and benefits of these 10 products. We’ve discussed what you’ll get after using each product. However, we understand that it’s like a maze to you. But don’t fret. We’re here to guide you to the product that best matches your needs.
Now, let’s start one by one-
Start with the Surface
While selecting a plastic epoxy for your project this is the first step. Check the surface types that you’re willing to bond. If it’s plastic to plastic then you can go for all the epoxies in our list. If there are 2-3 types of materials then the game gets hard.
In that case, you have to follow a step by step method. At first identify the material types. For example let’s say that you’ve got steel and plastic. Next, do a search for the word steel in our article. See if it’s mentioned in any product specifically.
If you found your material specific product from the article, then that’s awesome. If not, then welcome to the next step. Here, you’ve to go to the product page. There you can search for your material. Hopefully you’ll find yours.
Check the Bond Specs
On our 2nd step of the buying guide, we’ll check the bond specs. To be more specific, we’ll check the plastic epoxy strength and durability of the bonds. So, how to do that?
Well, in our article you’ll see that we’ve mentioned the epoxies that have high tensile strength. You’ll have around 5-10 products at your hand after the first screening.
Now you have to screen out the 3-4 epoxies that deliver a strong bond.
That’s not all-
Here you might want to look at which ones can handle after touches. We have mentioned if any of those can handle sanding machines and drilling machines. Just find the toughest ones.
Sort by Dry Time
After the second screening we believe you’ve got 3-4 products at hand. If not please try to bring down the product count. We have to decide with one at the end of the day.
From this step we won’t discard products with every step. Rather we’ll give points. The product with the best point will be the best one for you.
Now, back to the process.
You’ll notice two types of epoxies here. One type dries within 1 hour and another takes 24 hours+. For below 1 hour give 2 points and give 1 point to the ones taking more than an hour.
Categorize Based on Temperature Range
Here we’ll differentiate based on two categories. The weather category and the food safe category.
The weather category ones will be within -50 to 120 . However, for the food category you just have to see if the epoxy stays okay till 212 .
Now ask yourself if your project will remain outdoors or will it enter an oven. Whatever is your preference, now you know which category you’ll need. Find the products that fall into that category and give 1 point each.
Mark Based on Resistance
Normally epoxies should show resistance towards, water, sunlight, chemicals and fires. So, first decide what type of resistance should your epoxy show? Give points only based on those.
For example, let’s say you’ll only need water and sunlight resistance. So, you’ll give 2 points to the epoxy that meets these two criteria. 1 point if any epoxy meets only one criterion.
Check the Applicator Style
Here at first decide which type of applicator is best for you. Do you want easy dispense or equal dispense? Easy dispense is basically putties and tubes. Whereas equal dispense is syringe containers. Next ask yourself if a resealable cap will help you or not.
Let’s say you like equal dispense and resealable caps. So, you’ll give 1 point for each of those features. If you don’t like resealable caps, then 0 for this feature and 1 for the syringe container.
Container Volume/Weight Check
Finally, decide, do you want to reuse the epoxy many times. If yes, then give 1 point to the ones having more than 0.87 Oz. epoxy. If you don’t then give 1 point to the 0.87 Oz. epoxies.
Decide
Now calculate and see which product got the highest points. That one will be your best epoxy for plastic.
Frequently Asked Questions
Does epoxy eat through plastic?
Regular epoxy won’t hold on to plastic surfaces for that long. They just don’t have that structural integrity. But with the right preparation and product, it’ll stick to the surface just fine.
What is the strongest epoxy for plastic?
Well, we gave you the list of the epoxy for plastic surfaces. So, the rest is up to you.
Is epoxy stronger than super glue?
Both these products are great for strong bonds. But they’re used for different purposes. You see, super glue doesn’t have that much shear strength. Whereas epoxy is excellent in that field. So, for plastics, you should go for epoxy.
Does epoxy scratch easily?
The short answer is no. Epoxy will last longer than any other type of glue due to its structural integrity. If you’re worried about scratches, then don’t. Because that epoxy is not only scratch-resistant but it’s also extremely durable.
How long does plastic epoxy take to dry?
Normally, it’d take around 72 hours for the epoxy to dry completely. Even if the packaging says, 5 minutes is enough but you should still wait for it to dry properly. Otherwise, you’ll be putting yourself in the risk of surface contamination.
Wrapping Up
We’re at the end of our long journey. But we’re confident that from here on you can be by yourself. After all, how hard could it be to choose the best plastic epoxy?
That being said, remember to take safety measures while using the epoxy. Moreover, keep the epoxy out of children’s reach. So, what are you waiting for? Order up that epoxy, get your plastic ready and start bonding.
Good luck! Stay safe!
