With rubber-metal adhesive you can reliably connect two fundamentally different materials

One material is known for its flexibility, the other is robust and resistant: rubber and metal couldn't be more opposite. Therefore, to bond these two materials together, you need the right adhesive. In our range you will find special rubber-metal adhesives that adhere to rubber, steel or iron and a wide range of other surfaces.

Which adhesive is suitable for bonding rubber to metal?

It is important to know that rubber and metal are just umbrella terms for several different materials that have similar properties.

Rubber is an industrially produced material that usually consists of caoutchouc. Depending on the type of rubber, different additives and manufacturing methods are used. Therefore, it can be elastic, soft-hard, or very hard.
You must select the appropriate rubber-metal adhesive based on the strength and properties of the material being bonded.

Metal can also come in many different forms.
Like:

● iron  
● aluminum
● steel
● sheet
● copper

In addition, there are a wide variety of metal mixtures.
It can also be bare or have a treated, coated, or painted surface.
Even with metals, it is important to find out exactly about the type and properties of the material before choosing an adhesive.

An important factor when choosing a suitable adhesive for rubber or metal is the size of the area to be glued.
For small adhesive areas or strip applications, superglue is ideal (e.g. our cyanoacrylate adhesive); for larger areas of several square centimeters, a 2-component adhesive is recommended.
For areas measuring several square meters, however, you should use contact adhesives based on polychloropores (also called chloropen rubber or CR).

How to use rubber-metal adhesive correctly

When bonding metal and rubber, you must pre-treat the affected surfaces. For the metal-rubber adhesive to hold, it is best to work with solvents, cleaners, or other substances to thoroughly remove residues from surfaces. If metals are coated or otherwise treated, you should ideally sand them. After that, further cleaning is necessary.

Since rubber can become damaged or otherwise weakened over its lifetime, it is difficult to predict in advance whether the bonding process will be successful. It is therefore best to test the adhesive for metal and rubber on a small area in advance and evaluate the result after a few days.
If the experiment was successful, the adhesive is suitable and can be used over the entire surface. The bonding can then be further processed because the right rubber adhesive can be filed, drilled, or milled after it has hardened.

Tip: You can also use rubber-metal adhesive to fill cracks, bumps, or holes - for example in aluminum housings.

Can you also glue other materials with metal-rubber adhesive?

Rubber-to-metal adhesives can usually also be used in conjunction with other materials.
The WEICON Fast-Metal minute adhesive from our range can, for example, be used not only for metal and plastic, but also for fiber composite materials, ceramics, glass, stone, or wood.
The WEICON GMK 2410 based on polychloroprene adhesive connects rubber to rubber, rubber to metal as well as foam rubber, leather, felt, insulation materials, PE foam, wood, and textiles.

Even though rubber-metal adhesives can be used in a variety of ways, there are still materials for which they are not suitable (for example PVC). Therefore, always pay attention to the manufacturer's instructions before purchasing.

Are adhesives for rubber and metal waterproof?

Most rubber-metal adhesives are not waterproof and are also toxic to aquatic organisms - with long-term effects.
For example, they are not suitable for use in conjunction with aquariums. Cyanoacrylate glue is much better suited here.
