Epoxy is a great adhesive, but it’s not good at bonding to some materials. If you want epoxy to stick to plastic or vinyl then there are a few things you’ll need to know before attempting the job.
Does epoxy resin stick to plastic?
When it comes to epoxy, the answer is yes! Epoxy resin is a thermosetting plastic. It’s an inorganic polymer that can be used to bond two objects together.
If you have something made out of metal or plastic, this adhesive will work for you.
Epoxy resin was developed by the German chemist Dr. Hans Goldschmidt in 1889, but it wasn’t until the 1950s that its commercial use began to take off when NASA used it on their spacecraft and satellites.

Does epoxy stick to vinyl?
Epoxy resin is not compatible with vinyl. Epoxy resin is not compatible with PVC. Epoxy resin is not compatible with polycarbonate. Epoxy resin is not compatible with polyethylene.
Epoxy resin is not compatible with polystyrene.
Does resin bond to plastic?
Yes. Epoxy resin will bond to plastic. The type of plastic, surface preparation and temperature of the plastic will affect the bond strength.
Epoxy resin will bond to the same type of plastic only if that is what you are trying to attach it to – epoxy will not stick well to non-plastics (wood, glass).
If you want a strong bond from epoxy then make sure that there is no oil or grease on either surface and make sure both pieces being bonded are clean before applying any adhesive.
What is the strongest epoxy for plastic?
Epoxy resin is the strongest epoxy for plastic. It’s also the best epoxy for plastic applications, as well as the best epoxy for plastic repair and bonding.
When you need to fix something made of wood, metal or another material that isn’t plastic, you’d want to use a different type of glue.
How do you prepare plastic for epoxy?
To ensure a successful bond, you must prepare the surface of your plastic before applying epoxy. This can be done in a few ways.
- Cleaning it with water and soap: You can use warm water and soap to clean all surfaces of your plastic item. This will remove dust and dirt from the surface of your material, but it does not remove grease or oils that may be left behind by previous projects or manufacturing processes. These oils will prevent epoxy from bonding properly, so make sure you clean them off as well!
- Applying solvent: If you find yourself with an oily surface on your plastic product, use mineral spirits (paint thinner) or acetone to clean away any grease or oil before applying epoxy adhesive. Make sure that all surfaces are dry before proceeding with this step!
Will two part epoxy stick to plastic?
Epoxy resin is a strong adhesive. It can be used to bond many different types of materials in a wide variety of industries.
The epoxy resin is a two-part adhesive, which means that it must be mixed together in order to create the chemical reaction that will allow it to stick to other objects.
The epoxy resin is commonly used by construction companies, manufacturing plants and automotive shops because it has so many uses and properties that make it desirable for various purposes.
Can you use PVC for resin molds?
PVC is great for molds that need to be flexible, waterproof, or heat resistant. It’s good for flexible molds because it can be heated and bent repeatedly without breaking.
It’s water-resistant because of its chemical composition (it won’t absorb water), so it’s perfect for molds that may be washed regularly in your workshop.
And it’s a reliable material when working with high temperatures—in fact, some PVC boards are flame retardant!
If you plan on making plastic products that require complex shapes and intricate details like toys or figurines, PVC is a good choice because it will hold its shape after being formed into the desired shape by heating or applying pressure.
How do you get epoxy to stick to vinyl?
To get epoxy to stick to vinyl, you’ll need to clean the surface with rubbing alcohol and apply a primer first. Then, you can use a bonding agent like epoxy glue or construction adhesive.
First, remove any dirt or dust with a rag or paper towel dampened with some rubbing alcohol. Then, use acid-free tape (this means no masking tapes) to cover up any areas that shouldn’t be covered in adhesives, such as switches and buttons on electronics and components inside small gadgets like phones and tablets.
Next comes applying a primer: if you’re working with thin pieces of plastic like sheets of plexiglass or acrylic glass then choose an acrylic primer; otherwise, go for polyester-based because it’s more flexible than acrylics when used on thicker surfaces such as wood panels and furniture boards (including those made from MDF).
Finally comes applying the actual adhesive itself using your chosen method – either by brushing it onto one side at roughly half an inch intervals along each edge before placing down two parts together so they line up perfectly without overlapping; or by dabbing small blobs over both sides evenly so there aren’t any dry areas left behind when everything has dried out completely again.”
As long as you use the right epoxy product and follow the manufacturer’s instructions, you should be able to apply it to PVC boards without any problems.
However, if the board contains too much moisture or has been in contact with water for an extended period of time, it may not work as well. In that case, consider using plain old wood instead!
