Best Glue for Rubber

Rubber may be really durable, but it can still break or tear depending on what type of rubber it is, and if it does break you may end up trying to fix it. Sure taping it up sounds like a good, easy and quick fix, but it’s not a permanent fix since the tape can come off and it doesn’t really provide that much strength to hold the item together if it’s bigger in size. Check our article of the  Best Glue for Rubber.

The best solution in this case would be to use glue specifically made to stick rubber together since it’s something that cannot be done with your traditional glues. You can go from sticking together soles of your shoes and your boots to rubber pipes and garden hoses.

Glues made for rubber adhesion may be a handy tool to have at your disposal for whenever something happens, it can be a quick and easy way to repair any broken or torn down rubber you may have laying around and get it back to being useful again!

Types of Rubber

To get started, you need to first take a look at the types of rubber and know about them to understand what you’re dealing with first before you start bonding.

Nitrile rubber: This is one of the more common types of rubber that can be found in many everyday applications, things such as, conveyor belts, hoses, print rollers, cable jacketing and gaskets, so you get the idea.

Butyl rubber: This type of rubber is pretty flexible so it’s normally used in things like valve seatings, seals, linings, stoppers and even inner tubes.

Polyurethane rubber: This rubber is mostly used for modelling and in molds.

Natural rubber: It often offers some of the same features as nitrile rubber and butyl rubber since it can be used for gaskets and seals too, but other than that you can also see this rubber used in carpet backings and mountings too.

Silicone rubber: Silicone rubbers are a popular type, because of their high resistance to heat they are often used in ovenwares, cookwares, prosthetics and even medical devices.

EPDM rubber: This type of rubber are mostly used in seals, automotive hoses etc

There’s a lot more types of rubber out there, too many to list down but these are the most common types and mostly the ones that can be fixed with rubber glues.  

Steps to follow before rubber adhesion

Before you start glueing together your rubber you need to first degrease it, since rubber has a variety of uses it can easily have mold release or other types of lubricants or even slip additives on it, so  degreasing whatever type of rubber you’re using is important before you start bonding it since it may not work properly or have a weak bond otherwise.

When you’re degreasing, choosing acetone to do it may not be a good idea since it tends to be too strong and harsh on a few types of rubber, so if you don’t know the type of rubber you’re dealing with it would be better to not use acetone. A solvent degreaser would  work well. Isopropanol can be a great alternative to degrease your rubber instead of acetone.

Types of glues for rubber adhesion

You need a good knowledge about the types of glues you can get for rubber adhesion so you can choose the best one for your needs and glue your rubber.

Epoxies

They are a really strong glue made from the mixture of resin and hardener. Though it does need to be mixed at a proper ratio to get the right balance between strength and time, more hardener can make the glue stronger but take longer to cure. They usually form really strong bonds since they’re highly resistant against water, heat and many kinds of chemicals and solvents. 

Epoxies are also a great choice because they’re not just good for rubber but can be used with many other kinds of materials as well. 

Two Part Acrylic

These glues are similar to epoxies in the sense that they too use two components that need to be mixed into a mixture before use. They too form into a type of plastic when dried up and hardened just like epoxies, but for this glue it’s acrylic. 

They’re a good choice if you’re fixing something large in size or you have a big project since they don’t really need a big surface prep. 

Silicone Based

These types of glues are really flexible when dry, so if you’re in need of a glue that will maintain flexibility after drying then silicone based glues are your best bet. Once cured they are completely waterproof so if you’re going to repair something that will get in water often then it will make sure to work fine. 

They provide great rubber to rubber adhesion, you’ll also often see them used in aquariums because of their high water resistance. They are able to withstand heavy impact as well due to their flexibility and they also offer great heat resistance.

Cyanoacrylate

They are mostly referred to and known as super glue, they’re a quick and fast solution since they don’t take much time to set and cure. It can cure and dry in a matter of minutes, even seconds depending on the quality. 

They may not be as strong as the aforementioned glues but they do provide great tensile strength and are able to withstand almost any kind of damage.

With the modern advancements there are a great deal of amazing glues out there and it can be tough to choose from, some work better than others at certain points. But don’t worry, we have made things easier for you by sorting out some of the best ones you can get!
