How to Glue Rubber to Metal

When gluing rubber to metal, there are a few things to keep in mind, mainly concerning the integrity of the rubber material and the grit of the metal. To add a bit of grip, try lightly sanding the metal surface so the glue has a better surface to hold onto. From there, you should lightly wipe down the surface to remove dirt and dust that could interfere with the contact of the two pieces.

Select one of the specifically designated rubber to metal bonding adhesives and carefully apply a bit to each piece. Stick the rubber and metal together and hold it or clamp it in place until it has stuck fully.

How to Glue Silicone Rubber to Metal

Silicone rubber has a very smooth surface, making it extra tricky to fully connect with the metal. To attach these two items, follow the same basic directions in regards to prepping the surfaces but take extra care to select an epoxy rubber to metal bonding agent. This will help create a very strong bond despite the very smooth and slick surface area.

How to Glue Rubber to Aluminium

Again, the process is very similar. Due to aluminum’s structural nature, it is important to wash the area to be glued with mild soap and water, rinsing well. From there, lightly sand the aluminum then clean it again and apply the epoxy glue as you normally would.

Why is Rubber So Hard to Glue?

Rubber is a widely used product and, due to this, the specific makeup of each piece varies. Some have slippery agents, some have chemical additives to preserve color or shape. You may get one piece of rubber that is very flexible and another that is so stiff you cannot easily bend it. This means that when you order rubber as someone with no knowledge of what exactly is inside of the piece on a molecular level, you do not know exactly what you are getting.

This means that glue for rubber and other similar surfaces will have to be able to create a holding area via slight abrasion. Otherwise, the glue simply would not be able to hold onto the slick area and would not create a bond strong enough to be productive or effective.

The Best Glue for Rubber to Metal

There are a lot of different fantastic rubber to metal bonding glues on the market. These were selected due to their high reviews, pricing, and effectiveness. Any of these would be a fantastic choice that would serve most projects well. Let’s look at the benefits and pitfalls of each and what real-life reviewers have said about the formulas.

FAQ

Will silicon stick to metal?

With a bit of work, silicon can easily stick to metal. Silicon is a rather slippery and notoriously hard to glue item to work with. Fortunately, if you select a glue specifically designed for such a surface and work to sand the metal a bit first to create an abrasive surface, you should be all set.

What kind of glue works on metal?

Generally, epoxy glues are your best bet when working with metal. The glue can stick to the smoother surface of the metal without sliding around or otherwise creating air pockets that will cause the bond to break down in the future due to regular usage and exposure. Some other adhesives work well but by far, epoxy glue are the top option when working with metal.

Does hot glue work on rubber?

Hot glue is not the best choice for working with rubber. If the glue is too hot, it can actually melt lower quality rubbers or those with a lot of additives. Additionally, hot glue typically has difficulty attaching to very smooth surfaces since it dries in a rapid nature and cannot penetrate the surface of the smoothed zone. Lastly, hot glue bonds often do not act as permanent attachments. If you want a long-lasting bond, there are many better options available

Does super glue work on rubber?

Yes. Super glue is generally thin enough that it can permeate the surface of the rubber and create an abrasive enough surface for the bonding to occur. Stronger glue may work a bit better but for most general applications, super glue will work just fine.

Conclusion

When working with metal and rubber, adhesives can be tricky. Smooth surfaces are notably difficult to glue and can form bonds that degrade over time. Fortunately, there are plenty of options on the market that will provide a lasting, strong adhesion!
