Does super glue work on silicone? Superglue is a sticky product by brilliant minds. 

With the power to hold together different types of fabrics and items, superglues are interestingly inexpensive. They are readily available in abundance in both commercial and homemade types.

Although superglue has the ability to stick together different kinds of materials, there are those it cannot. 

In this blog post, we will figure out how it is manufactured to products it can or cannot hold together. Finally, we will look at whether superglue can work on silicone or not.

So in this article, we will delve into more facts about super glues. Are you going to miss this?

You should not.

Our answer would have been NO, but then in recent times, intelligent minds have enabled the potential of superglue to stick on silicone. So, in the real sense, some super glues work on silicone.

Surfaces That Super Glue Does Not Work On

surfaces wont work

In the simplest of terms, super glue is the most basic adhesive that can be reliably used anywhere for sticking purposes.

However, there are some surfaces that will not respond to the effects of super glue.

Top on our list is silicone which is at the center of our discussion. By no means shall silicon be stuck with ordinary superglue.

It takes a special type of superglue, made from silicon itself. Since only silicon can bind silicon.

Other surfaces that are repellant to super glue include any wet surfaces and polyethylene plastics of high density. Smooth surfaces, especially glasses, and other porous surfaces are included too.

Does Super Glue Work on Silicone? If Yes, What Type?

Superglue’s ability to bind together a variety of substances and materials gives it a wide range of applications.

super glue on silicone

It can be used in all industries, be it in metals, furniture, ceramics, rubber, vinyl, or plastics.

However, superglue does not stick to other surfaces, particularly plastics. Others are wet surfaces, smooth surfaces such as glasses, porous surfaces, and metal surfaces.

Most will dry, but not sticky, and can be lifted from the surface they were applied on as a solid when the solvent has evaporated.

Silicone is an elastomer rubber substance used in the manufacture of sealants, adhesives, lubricants, thermal insulators, electrical appliances, and cooking utensils.

Tip: Silicone can be found in a variety of forms, including oils, greases, rubbers, resins, and caulks.
reason why it dos not stick

It exhibits the following characteristics:

  • Low thermal conductivity.
  • Less toxic
  • Less chemically reactive
  • Waterproofness
  • Electrical insulation features
  • Non-Sticky
  • High gas permeability when put to room temperature

Commercial Glues that Work on Silicone

Below are some of the types of commercial glues that work on silicone

Solvent-Based Glues

Solvent glues are made up of a sticky base that promotes adhesion blended with chemical solvents that make the end product.

the solvent based glue

The solvent in the glue evaporates when applied to a surface leaving behind the adhesive that sticks.

Toluene is the most preferential solvent used in the making of superglue.

The solvent in this type of glue is usually water which evaporates when the superglue is applied to a surface.

As the water evaporates, the superglue dries onto the surfaces sticking them together.

Tip: Solvent-based superglues include liquid solders and other products like contact cement.

Water-Based Superglues

As an alternative to using chemicals, water-based glues that have water in them as solvent also come in handy.

They are slower to work with than the chemical solvent glues, but they are non-flammable.

Tip: Water solvent super glues can be made commercially or at home.

Two-Part Glues

the two part glues

Epoxy and resorcinol, crystalline phenols manufactured from organic resins, are examples of two-part glues.

The glue is in one part and the catalyst also known as the hardener is in the other.

They are highly handy for metal works (locomotive dent filler is a two-part adhesive), but they must be correctly mixed to work effectively.

Glue from Animal Products

Woodworking and veneering benefit from animal skin-produced superglues.

The glue, which is manufactured from animal hides, bones, and other animal parts, is sold either ready or in the form of a powder.

Cyanoacrylate Glues

C.A.s, or synthetic polymer adhesives, are the new superglue brand in the market.

the cyanoacrylate glues

A polymer is a complex molecule with simpler molecules (monomers) that bind together to form repetitive adhesive units.

The inherent desire was to build polymeric chains, as well as the ensuing molecular bonds and other glue based on them can be difficult to stop once a polymeric reaction has been accelerated.

Small quantities of C.A.s can be used for countless repairs in the home and workplace, including fixing broken ceramics, restoring joints, and even holding split fingernails together.

Note: Construction, medicine, and dentistry have all benefited from C.As in the workplace.

Does Superglue Stick to Silicone?

Does superglue work on silicone, or does any superglue stick-on silicone?

At the heart of this blog post, we sought to answer whether or not superglue can be stuck to silicone.

Our answer would have been NO! But in recent years, bright minds have enabled superglue to cling to silicone.

Because silicone is an elastomer at high temperatures, it used to be possible to bond it with superglue. That is no longer the case with new and improved superglue that can bind nearly anything.

However, these simple commercial superglues won’t work.

The only superglue capable of holding silicon together is Silicon glue or Silicone caulk. They have been prepared with a very hard tuck of a very hard silicone.

How Can I Bond Silicon Materials Together Using Super Glue?

We know a lot about super glue and how it works on Silicone, and we have already established that super glue does indeed work on Silicone.

But then, how do we glue two or more materials made out of Silicone Together?

how to bind silicone

Well, as we already know, Silicone (which we already established is a substrate of rubber), is quite challenging to bond.

In fact, it is one of the most difficult substrates out there that you can bond.

Relax, all hope is not totally lost!

The number of adhesives out there that could actually be strong enough to remedy this is quite a few in number, as only a few could actually form strong bonds.

What Kind of Glue Should I Use?

One great option for you would be to use an adhesive like 3M Scotch-Weld rubber and plastic instant glue.

It has been quite popular, producing a nice success rate when used on other Silicone substrates.

kind of glue

Another great option would be to use a Sil Poxy. It is quite popular considering the fact that it is used mostly in fixing torn moulds made of silicone rubber.

It is advised that you use Sil poxy on platinum cure or tin silicone, this is because the bond it provides between each silicone part is quite flexible but still strong with an increased elongation.

Does superglue work on silicone? The answer is Yes. Superglue sticks on silicone. However, the type and quality to stick silicone together matter a lot.

Silicone is a tough product that tends to resist most superglue. And as mentioned before, it is only special Silicone glue and caulk that can bind silicone together.

Are you looking forward to gluing together some sought silicon material? If you are, be choosy with the superglue you go for, otherwise, you lose.

We hope you select a superglue that sticks your silicone together. That is all we have, for now, I hope we have done justice to the question that plagued your mind.

Drink a lot of water, stay safe and of course stay productive, ciao.
