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.
The top best product [hide]
This product can be used on a wide range of automotive or non-automotive rubber to metal bonding applications due to its sticky, thicker formula. The flow control tip helps make repairs easy to pull off and creates the perfect tip for smaller spaces. All around, this is an amazing product worth having on hand. Just be sure to avoid skin contact, as some reviewers note it is an irritant and can be tricky to get off once it dries on clothing or skin.
The brand also notes that this product is weather, water, and vibration resistant, making it suitable for automotive use or where it will contact the elements or potential bumps and knocks. As a durable bond, you do not have to worry about this product slipping, sliding, or breaking, allowing for a secure, trustworthy adhesion once the product is cured fully. As a silicone adhesive, this is one of your best options, especially for tight spaces due to the skinny control tip.
