Eternal 99.99% Pure Acetone
It might surprise you that we put Acetone in this adhesive list for plexiglass, but we did so for a good reason. The 100% acetone has been proven to work excellently for plexiglass.
Here is how it works. You will need to submerge the part of the plexiglass you want to bond into a container filled with 100% acetone for around 60 seconds. After about 1 minute, the acetone will start to dissolve the plexiglass, and you can then take it out of the solution and join the pieces together.
What happens here is that acetone dissolves the plexiglass to a point where you can bond it to another piece of plexiglass. It’s sort of like welding plexiglass, and this makes the bonds unbelievably strong. You will not be able to get this strength of the bond with any adhesive.
The key here is to use only 100% acetone like this one. It won’t work with regular nail polish removers that contain other solvents. Make sure to get this one, and the results will be phenomenal.

What To Look For When Choosing Glue For Plexiglass
We will now go through the most important features and properties that you should look for when choosing plexiglass glue. But first, let’s learn a bit more about plexiglass itself.
According to wikipedia:
Plexiglass is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass.
wikipedia
And that’s exactly what it is, a thermoplastic that is used as an alternative to glass. The most important thing to remember here is that the plexiglass is thermoplastic.
This means that specific glues with enhanced methyl methacrylate adhesion properties work really well on plexiglass. We will now go through those adhesives and see which one is the best for different applications.
Type Of Glue
Three types of adhesives are the most efficient for bonding plexiglass, cyanoacrylates, epoxies, and acetone.
Those three types of glue will work excellent with plexiglass and will provide you with long-lasting results.
Cyanoacrylates
AKA super glues. These adhesives are known to work on almost all materials you can think of. Plexiglass is one of those materials that react superbly with CA adhesives.
The main advantage here compared to the other adhesives we mentioned above is the compatibility with a wide variety of materials. You can bond plexiglass to wood, metal, stone, ceramics, and much more.
If your plexiglass project involves different materials, super glue is your best bet. It will save you from buying several different adhesives for one project, which never quite works.
Another advantage of the superglue is that it’s beginner-friendly. Anyone can use superglue since it’s a single component and only requires you to hold the pieces together for a few seconds to join them properly.
Epoxies
Epoxies provide bonds of industrial strength. The tensile strength of these adhesives usually exceeds 3000 PSI and can go up to 5000 PSI and beyond.
Apart from their strength, they also have tremendous resistance to high and low temperatures as well as being waterproof. They are ideal for outdoor plexiglass projects where you need that extra resistance from environmental factors.
The downside here is that epoxies take a lot more time to dry and are tricky to work with if you don’t have the experience. If you’re willing to put some effort into testing the epoxy and learning how to mix it, you can enjoy the benefits of its industrial-grade properties.
Acetone
Acetone isn’t an adhesive per se, but it works marvelously for joining plexiglass. It dissolves the thermoplastic in plexiglass and makes it able to be joined with another part. It’s very similar to welding, just with plastic and acetone instead of the torch.
If you choose to go with acetone, the advantage will be the strength of the bond. You will achieve a bond that is more resistant than any glued bond.
This method can be a bit tricky, but if you get the hang of it, you will save money and also end up with the most durable and powerful bond of all.
Different Materials
If you want to attach plexiglass parts to another material like wood or metal, your best bet will be to use super glue or single component epoxy.
Adhesive like E6000, which is epoxy-based, works on countless materials and holds its bond incredibly well. You can also use CA glue which is known as a versatile adhesive that can bond to anything.
Both of these work well. Just make sure to choose the high-grade models that have a good reputation for bonding the desired material.
Viscosity
To choose the right viscosity, you need to figure out the amount of time you want to have for working with the glue.
Liquid or low viscosity is out of the question for plexiglass. It will spill, and ruin your project. It’s simply not accurate enough in the application for it to be useful.
Medium viscosity is ideal if you want the glue to cure quickly while having a gel-like consistency for an accurate application.
If you prefer having more open work time with the adhesive, choose the high viscosity models. They will provide you with great consistency and enough time for assembly of the parts.
Setting & Curing Time
The setting time for the adhesive should be chosen based on your preference. If you want more time to work with the glue, go for setting times of 3 minutes and above.
If you prefer to finish the work as quickly as possible, then a quick setting super glue is the right choice.
The curing time varies a lot between different adhesives. Epoxies can have curing times of up to 48 hours, while super glues can fully cure in only 60 seconds.
Environmental Factors
If your project is exposed to moisture or extreme temperatures, an epoxy adhesive is your best bet.
Cyanoacrylates don’t have the environmental resistance of the epoxies and won’t be sufficient for outdoor use.
Acetone works great in any kind of environment since the bonds aren’t glued and are not prone to breaking from temperature change or water.
Frequently Asked Questions
