can epoxy resin be used on plastic?

Epoxy resin is used for many different things. It can be used to fill in cracks and holes, as a sealant for windows, doors, roofs, and even on walls.

But does epoxy work on plastic? Does it stick to hard plastic? Can you use two part epoxy on plastic cups? Well in this article we will answer all these questions and more!

Does epoxy resin stick to hard plastic?

Epoxy resin is not a glue. It’s a bonding agent that causes materials to chemically adhere to each other. The epoxy resin molecule has two parts: an active part and a curing agent.

The active part of the epoxy resin molecule reacts with, or bonds with, another material while the curing agent hardens into a solid. Epoxies are designed to bond different types of materials together and create an incredibly durable bond between them.

Because it’s specifically designed for bonding plastics, you should use epoxy resin on any kind of plastic as long as you follow directions carefully and clean your surfaces thoroughly before beginning this project (it is important for good adhesion).

How do you apply epoxy to plastic?

  • The first thing you need to do is clean the surface of your plastic with an alcohol wipe, which will remove any dirt or grease that might interfere with the bond between epoxy and plastic.
  • Mix one part B-72 epoxy resin with two parts hardener (mixing ratio by weight).
  • Apply a thin film of epoxy in small sections at a time, spread thinly and evenly across all surfaces of your model or piece of furniture you’re making repairs on using an applicator brush or foam roller.
  • Let cure for 24 hours before handling it again (or sooner if using low temperature cure catalyst)

Can you put resin on plastic?

You can use resin on plastic. In fact, you can use it with just about anything! Here are some ways to get started:

  • Use a plastic brush to apply the resin. Plastic brushes are generally easier to handle than traditional brushes, but they don’t hold as much paint at once.
  • Use a plastic roller to apply the resin. Rollers are more durable and allow you to cover larger areas in less time, but they’re harder to control than brushes and require more effort when cleaning up excess paint or other materials that may have gotten on them during application (such as wood filler).
  • Use a plastic squeegee after applying the epoxy resin (or whatever material) using either of these two previous methods (spraying/brush/roller). This step is necessary so that any excess material doesn’t get trapped under your project’s surface; otherwise, it could cause bubbles or wrinkles later on when everything dries out completely.”

What kind of epoxy is used for plastic?

When it comes to plastic, you have a few options. The first is epoxy resin. Epoxy is a two-part adhesive that is used to bond or repair plastic. It can be used on most plastics and will not damage the surface of the material if applied properly.

Epoxy resin has many advantages over other adhesives when it comes to bonding plastic:

  • It dries hard and clear
  • It’s easy to use (just mix the two parts together)

What are the disadvantages of epoxy?

One of the disadvantages of epoxy is that it’s not food safe. Epoxy will not be able to withstand the high temperatures needed for foods like butter and cheese, so if you are using epoxy for anything related to food, you will need to find a different material.

Another disadvantage is that epoxy resin can be harmful if used without proper safety precautions. It’s important to remember never to breathe in fumes from uncured resin or mixers as they can irritate your lungs and nose.

Also make sure you wear gloves while working with any type of epoxy resin powder because it can cause skin irritation if it gets on your hands (even if cured!)

Can you epoxy plastic tumblers?

Yes, you can use epoxy resin on plastic. However, if you’re using the resin to bond two pieces of plastic together, it will be best to choose a product that is made for bonding plastics.

A general purpose epoxy such as J-B Weld or Loctite Plastic Bonder will not be strong enough to hold the two pieces of plastic together without coming apart after some time.

You should also make sure that the surfaces you want to bond are clean and free of debris before applying any adhesive or sealant product like an epoxy resin. Be sure not to leave any surface cleaner residue behind when applying your adhesive!

Will two-part epoxy work on plastic?

Epoxy resin is one of the most versatile adhesives available. It’s used for bonding plastics to other materials, repairing cracks and scratches on your car’s plastic bumper, coating parts of your boat with a waterproof barrier, and more. The list goes on and on.

The short answer? Yes! Epoxy can be applied to any kind of plastic surface. If you’re unsure whether or not it will work for your particular project, just ask us at the store!

Can you use epoxy on plastic Starbucks cups?

Yes! You can use epoxy on plastic Starbucks cups. The key to making this happen is to find the right cup and the right kind of epoxy.

For example, I used a clear plastic cup that had been sitting in my car for days and my first attempt at using epoxy with it failed miserably because the cold weather and condensation had made the cup too rigid.

You’ll want to find a cup that isn’t too thick or sturdy so that it can be cut easily and then you can use your mosaic artistry skills to create whatever kind of design you want.


It is easy to apply epoxy resin to plastic, but you need some basic knowledge about this. You can use the two-part epoxy resin or the single-component one.

It’s up to your choice and preference which one you want to buy because both of them have their own advantages and disadvantages.

The disadvantage of using epoxy on hard plastic material is that it will take time for the resin to cure properly before it becomes usable again so if you are going out somewhere in an emergency situation then using this type of adhesive may not be ideal for such situations.
