A lot of people ask me if epoxy adheres to silicone, but they never ask if I’ve ever tried it. Well, yes I have! And yes, it works great.
In fact, epoxy sticks to almost everything but itself and water. So your next question is probably: “what about the resin?” The answer is also a resounding “yes”: resins stick wonderfully to silicone surfaces too.
All this talk about adhering things together might make you wonder what epoxy doesn’t stick to… in which case you’re in luck because there’s not much!

Can I use epoxy on silicone?
Silicone is a synthetic rubber, and epoxy is a thermosetting plastic, so they are both polymers. In fact, silicone is also an epoxy resin—it’s just not as strong as regular epoxy. Since both are polymers and resins, you can use them together in many different ways to make your life easier!
If you’re wondering whether the silicone will adhere to the resin on its own or if you need another type of glue to hold it all together… well there’s good news for you!
Both materials stick extremely well with each other at room temperature (or even warmer), so no additional gluing should be necessary except maybe around edges where seams meet up with each other.
Does resin stick to silicone?
Good news: yes! Epoxy adheres to silicone just fine.
Silicone is rubber, so it’s technically a polymer. And epoxy resin is also a polymer. So in that sense, they’re kind of the same thing!
In fact, you could use the word “epoxy” to describe anything that has two parts that bond together when they’re mixed together and cured with heat—and there are lots of things called “epoxies” out there besides epoxy resins!
For example, some window caulking contains an epoxy resin and polysulfide rubber (or sometimes polyurethane) as its ingredients.
So if you’ve ever had trouble sticking your window screens back into place after removing them for cleaning or repair work, try silicone caulk instead of screen adhesive next time—it’ll be much more likely to stick until you get around to repairing those windows permanently later on down the road.
Does 2 part epoxy stick to silicone?
Epoxy resin does adhere to silicone. In fact, epoxy is more durable and flexible than silicone.
Epoxy is resistant to heat, water, and oil. It can be used in marine applications as well as electrical applications because it is non-conductive.
Epoxy can also withstand UV radiation from the sun without degrading over time or losing its strength or elasticity which makes it an excellent choice for outdoor use on a boat or pool area where harsh weather conditions may exist such as rain, snow, and ice build up that would cause damage to surfaces such as wood decks if they were not protected by something like epoxy coating which has already been applied prior to installation of any furniture pieces just like what happened here at our client’s house!
What adhesive will stick to silicone?
The answer to the question, “What adhesive will stick to silicone?” is: not epoxy or any other adhesive. However, you can use silicone as a release agent for both epoxy and resin.
If you’re wondering how to work with silicone in your projects, read on!
What does epoxy not stick to?
Epoxy will not stick to silicone. It also does not stick to glass, metal, wood, ceramic, or rubber. If you’re using epoxy on a concrete floor and are worried about it getting stained or damaged by the material underneath it (say if you plan on staining your concrete afterward), then make sure that you have some extra on hand so that when the stain isn’t exactly where you wanted it (or worse yet: bleeds into other areas altogether) then you can try again!
Epoxies generally don’t adhere well to plastics either but this depends on what type of plastic we’re talking about here.
Some types of plastics are more porous than others which means some epoxies will adhere better than others.
Does epoxy stick to rubber?
The answer to this question is simple: no, epoxy does not adhere to rubber. In fact, epoxy will not adhere to many things if you are trying to use it in a normal way.
Epoxy is not meant to be used as an adhesive between two materials; it’s meant for high-performance applications where strength and durability are more important than flexibility or ease of application.
What makes epoxy so great at its intended purpose (adhering two surfaces together) is also what makes it terrible at other things like sticking stuff together by hand.
Epoxy has very poor conductivity properties—meaning that heat and electricity don’t flow through it well.
In order for electrical current (or any kind of energy) to flow through something like rubber, there needs to be something called resistance present in the material being bonded—the greater the resistance, the better chance there is that electricity or heat will get trapped inside without escaping out into space where it can do damage or cause problems elsewhere in your system (like maybe frying your motherboard).
This means that if you try applying some epoxy directly onto the surface of your rubber boots without first preparing them with something like silicone lubricant first then chances are pretty good.
Why is my epoxy resin sticking to my silicone molds?
If you’re having trouble getting the epoxy resin to adhere to silicone molds, it’s likely a matter of not using the right product.
- Use liquid epoxy instead of gel or powder forms of the resin. While gel and powder versions are easier to work with because they’re less viscous than liquid resins, they don’t stick as well and can cause bubbles in your final product.
- Add a release agent like wax or oil-based paint thinned with turpentine (a natural solvent) or mineral spirits (a petroleum-based solvent) onto your mold before dipping it into liquid epoxy resin. This will help break down any oils on the surface of your silicone mold so that it adheres better with less chance for air bubbles forming during curing time later on downstream inside molds filled up with molten material poured into them from above where temperatures get much hotter than room temperature atmospheric conditions outside environment surrounding you right now while reading this article online via computer screen right now reading stuff written here yeah I’m talking about all kinds just basically anything that might get sticky making sure nothing sticks anywhere near anywhere else.
Can you use silicone molds for epoxy resin?
You can use silicone molds for epoxy resin. However, you’ll probably need to use a release agent with your silicone molds because they are more flexible than epoxy resin.
The purpose of using a release agent is to help the epoxy resin release from the mold easily when you’re ready to remove it from your mold cavity.
If you decide that you don’t need to use a release agent, then simply pour your epoxy resin into your empty silicone molds and let it cure.
You’ll want to make sure that there aren’t any air bubbles trapped inside of them before pouring in your liquid rubber so that none of these pockets causes issues later on down the line when removing parts from their respective cavities.
So, in short: yes! Epoxy will stick to silicone. The only problem is that it’s very hard to remove from the silicone molds after it has been cured.
This article will help you understand how to prevent epoxy resin from sticking to your mold when casting with it and what kind of adhesive you should use on the surface so that nothing sticks afterward.
