Our Top 4 Epoxies For Plastic
If you're truly looking for the best epoxy to use for your next painting project, you're in the right place!
Below is a list of our top 4 epoxies, keep reading to learn about the pros and cons of each one:
Remember that you must apply pressure for the glue to fully adhere to the surface of whatever you’re gluing. We realize that sometimes two objects can’t be clamped with the tool, and you’ll have to press them up against each other for the proper amount of time (somehow). For example, Loctite super glue can glue up cut fingers quickly if you hold them together for about 30 seconds.
Be careful when clamping to not over clamp and break the glued surface. Proper clamping is crucial for adhesion strength, so think it out very thoroughly before performing the gluing process. There are a few different types of clamps and various forms of clamping techniques. We’ve provided you with some great clamping techniques to help you master any glue job.
You’ll want to sand some surfaces before applying epoxy adhesive liquid also. The way you sand the project depends on the project. For example, if you’re gluing up two pieces of plastic, it will help to sand it to 120-grit first.
Another example would be if you are gluing two pieces of hardwood together. You’ll get the best results for adhesion gluing if the hardwoods have been run through a plainer and then edged.
What Is Epoxy For Plastic?
Plastics are a huge commodity in our everyday lives. Although plastic and plastics science for recycling purposes has been limited in the past, the future is bright, but plastic still breaks.
The good news is that super glue/cyanoacrylates and clear epoxy get the job done. Just be careful when using epoxy on polyethylene/polypropylene, as it won't adhere and can even damage/decay the surface of your project.
What Are The Different Types of Epoxy For Plastic?
Pick any brand of epoxy made specifically, and you'll be virtually purchasing the same thing with a different name all across the board. The kit comes with two tubes of glue, Part A and Part B. Part A is the epoxy and Part B is a hardener.
When mixed, they form a nearly irreversible bond. With the durability to withstand high temperatures, epoxy is a great choice for permanently gluing many objects.
When performing a heavy-duty plastic repair, you might need tools like an applicator, stir stick, filler, clamps, acetone/solvents, etc. -- you can find everything you need for the best price on Amazon.

How Does Epoxy For Plastic Work?
The process of gluing with epoxy is simple, and it can be broken into a few steps:
First, you must identify what you will be gluing. If it’s a broken pipe, observe all points of contact. If you're gluing together two larger pieces of plastic, the idea is to smooth the surface as much as possible before gluing.
Prep the surface by sanding and smoothing. If sanding isn't possible, clean the surface as much as possible before mixing the epoxy.
Glue + clamp
Don't forget that just because it's epoxy doesn't mean it's just going to stick without applied pressure. Always try to clamp your project's firm so the epoxy is as strong as possible.
What To Look For In The Best Epoxy For Plastic?
The best things to look for are a good price and good reviews. Here are a few more details to keep an eye out for:
Look for expiration dates.
Old super glue or epoxy won’t work as well as the fresh new stuff.
Most epoxies have something like ~30-minute set times between products, but use the manufacturer's label to better understand the process. Remember, one part epoxies will damage acrylic surfaces, so always use a two-part epoxy when working with anything acrylic.
Some epoxies are thicker than others, and clear epoxies are best for hiding a glue job. We recommend becoming familiar with each of these products for a better understanding of what to use for each specific project.
Also, look for the correct glue for your project.
For example, gluing a ski edge to the ski requires super glue and c clamps, and industrial epoxies only cure correctly with carbon fiber when the correct amounts of heat and pressure are applied.
Another example of choosing the correct glue for the job is if you were gluing a low-pressure hose back together. Yes, gluing a hose back together is always easier with a clean surface, but a two-part epoxy will do a better job closing the gaps compared to super glue. Like what if you can’t reach the hose on your window washer fluid hose, but it needs a glue job right down next to the reservoir in an ‘out of clamp’ position?

Our Reviews Of The Best Epoxy For Plastic
Loctite makes some good stuff. When clamped correctly, Loctite super glue sticks metal and plastic together well enough to lay up carbon fiber or fiberglass over the top—now that’s adhesion
That being said, Loctite glue has less body than a two-part epoxy, so you have to know your glue when performing repair or production.
Loctite epoxy is some of the best glue for handling the biz. Use this high-strength solution for a flawless glue job.
J-B Weld is fantastic for repairs like automotive (gluing an oil pan, for example), so you are going to want any type of J-B weld in your arsenal if you’re a handyman. J-B’s epoxy putty is amazing for fixing pipes, plastic boxes (airlines), etc. just for your further knowledge.
Pick #2: Gorilla 2 Part Epoxy

With two resealable part 'A' and part 'B' containers, Loctite can be reused again and again.
The other great part about Loctite plastic bonder is that it can be drilled, sanded, and it dries clear as to not leave an ugly appearance on your project (great for jewelry).
Final Thoughts On Best Epoxy For Plastic
Now, this article is mostly based on epoxies for making repairs for plastic, but you should educate yourself about epoxy resins applied to surfaces like carbon fiber, and epoxies for injection molding.
What are injection molding epoxies?
That’s where forms are either handmade or cut by a 3D printer to accommodate pouring epoxy inside. Forms typically have two parts that come together once the epoxy is poured inside.
What’s the difference between epoxy and polyurethane?
Epoxy is also technically a flexible plastic, but its chemical reaction cures on a linear level when compared to polyurethane. It starts in a liquid form and transforms into a solid form one time whereas polyurethanes cure instantly and have the potential to take softer shapes like foam, bendable plastic, etc.
Curing time for epoxy depends on the product, so read the label on each specific product for the best results.
