can epoxy be used on plastic?

Epoxy is a two-part adhesive that’s incredibly strong and bonds to just about anything. When you use epoxy to fix something, it’ll last for years without showing signs of wear or need maintenance. Epoxy bonds well to wood, metal, ceramic tile, and other surfaces, but it can also bond to plastic.

In fact, epoxy resin is an important part of many manufacturing processes involving plastic because it makes the material stronger and more durable.

What’s the best epoxy to use on plastic?

Epoxy is a super-strong glue, sealant, adhesive and cement. It’s one of the most versatile materials you’ll find in your garage or toolbox.

You can use it to permanently bond wood together and make a sturdy repair job on any surface—from plastic to metal to glass.

It’s important to know that not all epoxies are created equal. Some are designed specifically for certain jobs and won’t work on others because they don’t have the same properties or chemical makeup.

While we’ll go into more detail about this later in our section on epoxy types below, it’s good to keep it in mind when shopping for an epoxy product: if you want something that works well with plastics (and other materials), look for brands labeled as “plastic” or “polymer.”

Does epoxy resin stick to plastic?

Epoxy resin is a strong adhesive, and it will stick to plastic. Epoxy resin is also known as epoxy glue, epoxy sealer, epoxy coating, and more. It can be used on many different surfaces including wood, metal and concrete.

How does epoxy bond to plastic?

Epoxy bonds to plastic in three different ways:

  • Chemical bonding. When the epoxy has a higher affinity for one of its components, it will cause a chemical reaction that draws those components together.
  • Physical bonding. Epoxies can produce friction between two surfaces and the more pressure is applied, the stronger this bond becomes.
  • Mechanical bonding occurs when an epoxy sticks to its surface through physical force or adhesion due to surface tension between them

Is Gorilla Epoxy good for plastic?

Gorilla Epoxy is a high-quality epoxy that works well on plastic and other surfaces. It’s perfect for repairing cracks or filling holes, as well as for making custom designs and sculptures.

The product comes in two different versions—white and clear—and both are good choices for crafts and DIY projects.

What plastic does epoxy not stick to?

Epoxy doesn’t typically stick well to plastics that are too thin, or those that have been treated with a release agent. Epoxy also tends to be less effective when used on plastic surfaces that have been painted, or those treated with a solvent (such as paint thinner) since the solvent can affect how well epoxy bonds with the plastic.

On top of that, epoxies can sometimes take longer to cure than other adhesives because they’re designed to create a hard-as-rock protective covering over whatever object you’re working on.

You’ll also want to make sure your plastic surface is free from any roughness or bumps before applying epoxy onto it—if there are any small imperfections in your surface then it could keep the epoxy from sticking properly!

Can you put epoxy on plastic tumblers?

Epoxy is a strong adhesive, and it works well with plastic. Epoxy can be used to bond two pieces of plastic together. The only thing you need to make sure of when gluing plastics together with epoxy is that the epoxy is compatible with the plastic and will not cause any damage to it.

You also want to make sure that the glue has a high enough viscosity so that it won’t run off or drip out when you apply it.

When choosing an epoxy, look for one that has good adhesion properties, high strength, good corrosion resistance (so it will last), good chemical resistance (so water does not affect its durability), wide temperature range (-40°C / -40°F up to 150°C / 302°F) and low viscosity (so it will spread easily).

What are the disadvantages of epoxy?

Epoxy is a two-part adhesive that must be mixed together before use. The epoxy will take time to cure, meaning that you must wait for it to harden before using it.

Epoxies are stronger than super glue, but not as strong as super glue when used in large amounts. This means that epoxies don’t work well for large repair jobs or if you want something with maximum strength.

Epoxies aren’t as flexible as super glues either; they won’t hold up as well under stress such as bending or twisting pressures.

Finally, while epoxies are typically heat-resistant (they can withstand temperatures up to 350 degrees Fahrenheit), they’re much less resistant than other adhesives like silicone sealant or hot glue gun adhesive (which can withstand temperatures up to 500 degrees).

What is the strongest glue to use on plastic?

Epoxy resin is a great choice for bonding plastics, but you should keep in mind that it’s not as strong as some other glues.

If you’re looking for a glue that can hold up to rough handling and repeated use, epoxy resin may not be the best choice. A more rigid glue would be better suited for those purposes.

But if your plastic is going to be used in a stationary setting and won’t need to withstand much wear or tear, epoxy resin might just be what you’re looking for.

In particular, epoxy resin is ideal when you’re working with plastic tumblers (aka shot glasses). It has excellent adhesion properties on smooth surfaces like glass and plastic so it’s perfect for making sure your shot glasses stay put!


In conclusion, there are many options for gluing plastic. When it comes to strength and durability, epoxy is a great choice. If you don’t need such a strong bond, hot glue or silicone caulk can also work well on some types of plastic but not all.
