People commonly use epoxy to repair broken items or fill in gaps and scratches. However, there are so many products on the market it can be hard to choose. What is the best epoxy for plastic?

The best epoxy for plastic is the Gorilla 2 Part Epoxy. It is simple to use, gives a strong and durable bond, and dries clear. You can reuse the product since the epoxy and hardener are separate within the syringe.

This article will cover what epoxy is, what you should consider before buying epoxy, and why the Gorilla 2 Part Epoxy is the best overall. I will also discuss a few other alternatives you may want to consider for different kinds of projects.

What Is Epoxy?

Epoxy is a thermoset plastic that is a few different industrial chemical compounds. Epoxies have several beneficial characteristics, such as strong adhesion, chemical resistance, and toughness. Due to these reasons, many companies use the substance for industrial purposes.

One of the most popular uses for epoxy is adhesive since it is so strong. Companies use the material to make products such as laminated wood and concrete. Epoxy is also used as an adhesive for glass, wood, concrete, and metal since it is heat and chemical resistant.

However, epoxy is not only for industrial purposes. Many crafters and DIYers use epoxy as adhesives since it can come in different forms, including flexible, rigid, opaque, or translucent.

Finally, you can use epoxy as a coating or a sealant for projects. Since the material is so durable, people use it to create strong, glossy finishes on surfaces such as concrete floors, wood, and other industrial projects.

What To Consider When Buying Epoxy for Plastic

Since epoxy is such a versatile material, there will be something to consider before buying a specific product. Epoxy can come in so many different forms, so you will need to know what you need for the project to find the right one.

I’ll explain the three factors you need to consider below.

What Is the Product Designed For?

You need to be careful when buying epoxy for plastic because there are epoxy products for many different materials such as metal (like aluminum), woodwork, and cement.

When using epoxy for adhesive purposes, there is a thing called ‘working time.’ The product comes in two separate forms that you have to mix before you begin applying. Once you mix the epoxy and hardener, there is only a certain time where you can manipulate the material.

For some epoxy products, the working time is only a few minutes. For others, it can be hours. It all depends on what product you buy, so it is crucial to know what material the product is for.

What Are You Using the Product For?

You need to consider what you are using the product for before choosing one. The two main uses of epoxy for plastic are for adhesive purposes and to fill in gaps, dents, and scratches. If you are using epoxy for a simple repair and adhesive job, you won’t need a lot of working time. However, if you use the product to fill in multiple gaps or scratches, you will need an epoxy with more working time.

Another thing to consider is how large the project is. You might need to find an epoxy with up to 60 minutes of working time to repair a large plastic object such as a car part.

Do You Need a Flexible Adhesive or a Rigid Adhesive?

One last thing you will need to consider is how rigid you want the epoxy to be. Some glues dry very hard, while other glues are more flexible. The kind of glue you buy will depend on the type of project you are tackling. There is also epoxy putty that you can use for some repairs, such as fixing a PVC pipe. Epoxy putty will be one of the most flexible epoxy products out there.
