METAL ADHESIVE GLUE: Strong Metal Bonding

If you are looking for a glue or adhesive to bond metal then Adiseal has been shown to be the strongest adhesive in an independent metal adhesive strength. Adiseal was shown to be the strongest adhesive in the metal to metal adhesive bond strength test as well as the wood to metal bond strength test.

Adiseal is suitable at sticking and gluing metals of different types including steel, aluminium, iron, copper, brass, lead and much more. Adiseal provides a strong, flexible, waterproof and durable adhesive bond on different materials. Our Adiglue is also a metal glue that provides a fast glue bond on metal and other materials.

  1. Adiseal : 245 psi
  2. SupaBond : 224 psi
  3. Tec 7 : 165 psi
  4. HB42 : 184 psi
  5. Loctite PL Premium : 202 psi
  6. Gorilla Grab Adhesive : 166 psi
  7. Bond It PU18 : 136 psi

As well as Adiseal being the strongest at bonding metal to metal, Adiseal adhesive sealant is also the best adhesive at sticking wood and metal together. In an independent wood to metal adhesive strength test by Ultimate Handyman, Adiseal was the strongest adhesive. It was over 3 times stronger than the nearest competitor in the wood to metal adhesive glue strength test. In fact it was so strong that the screws holding the metal sheet down started to rip out forcing the test on Adiseal to be stopped.

Test results

During the bond strength examination between hardwood and metal, Adiseal demonstrated remarkable resilience, enduring a substantial pressure exceeding 3123+ psi. In stark contrast, all other product bonds faltered under pressures of 1115 psi or less. The graphic representation below shows Adiseal’s outstanding performance in the adhesive strength test, proving it’s the best adhesive.

Strength demonstration of Adiseal on metal

To demonstrate the strength of Adiseal, we bonded 2 steel hook plates together with Adiseal. Once the adhesive cured, we then used the steel hook plates to tow a 2.7 tonne van to demonstrate the high adhesive strength of Adiseal. The images below show the process of our demonstration.

We applied Adiseal to attach 2 metal to metal hook plates together.


Bonded metal hook plates connected to tow cable for strength demonstration.
Once the metal glue adhesive had cured, we hung the metal hook plates to the van tow eye.

We then used a steel towing cable hooked to the hook plates.

The other side of the steel tow cable was connected to another vehicle to pull the van.


Our demonstration showed the ability of Adiseal to stay bonded between the metal plates without breaking even under heavy stress. The video below shows how we carried out the demonstration.

How to stick metal with a metal glue adhesive

How to stick metal with a metal glue adhesive

  1. Surface preparation

    Clean the metal surfaces that will be bonded together. Remove any dirt, grease, oil, rust, or other contaminants using an appropriate cleaner or solvent. Ensure the surfaces are dry before proceeding.

  2. Spray water

    Adiseal requires moisture for it to cure which it normally gets from the air. If applying the adhesive between 2 non-porous materials like metal, then spray a little water onto the material surface before applying the adhesive.

  3. Apply the adhesive

    Apply the adhesive evenly onto one of the metal surfaces. Apply enough adhesive to create a sufficient bond, but avoid excessive application that can cause squeeze-out or messiness.

  4. Join the metal surfaces

    Align the metal pieces together and firmly press them together. Apply pressure to ensure good contact between the surfaces and to spread the adhesive evenly. Sliding the items side to side can help spread the adhesive to cover more surface area.

  5. Temporary supports

    Use clamps or other holding mechanisms if necessary to keep the pieces in place during curing.

  6. Curing time

    Allow the adhesive to cure as per the manufacturer’s instructions. The curing time can vary depending on the adhesive type and specific product. Follow the recommended curing temperature and humidity conditions for optimal bonding strength.

  7. Post-curing and handling

    After the adhesive has cured, avoid stressing the bonded area for the recommended post-curing time. This allows the adhesive to reach its maximum strength. Once fully cured, handle the bonded metal with care and avoid subjecting it to excessive forces or stresses that could compromise the bond.

Tip: To store Adiseal once opened, leave about 1cm worth of product out of the nozzle and store the tube upright in a cool dry place. Adiseal requires moisture for it to cure. The exposed part out of the nozzle will cure creating a cap. To re-use Adiseal, pull the cured part out or cut the nozzle until the uncured part is reached.

Frequently asked questions about bonding metal

How to bond metal without welding?

You can join metal to metal without welding by using mechanical fasteners, rivets, or adhesive. When using adhesive, ensure both surfaces are clean, removing any oil or grease. Apply the adhesive, press the metal together, and maintain pressure until the adhesive dries. Temporary supports may be needed during the drying process.

What is the best glue for metal to metal?

Adiseal is the strongest adhesive in an independent test. It was strongest in the metal to metal bonding strength test. It was also over 3 times stronger than anything product in the wood to metal glue adhesive strength test.

What is the strongest glue for metal to metal?

The strongest adhesive in an independent metal to metal glue adhesive strength test was Adiseal. It also was strongest in the wood to metal glue bonding strength test.

How do I prepare the metal surface for bonding?

Surface preparation is vital for a strong bond. Clean the metal surface to eliminate dirt, grease, oil, or rust. You can enhance adhesion by abrasion with sandpaper or a wire brush. Depending on the adhesive and metal type, additional surface treatments like primers or etching agents may be necessary.

Can I bond metal to other materials, such as plastic or glass?

Metal bonding adhesives are versatile and can often bond metal to other materials like plastic, glass, ceramics, or composites. However, ensure you choose an adhesive compatible with both the metal and the material you intend to bond.

What is the best adhesive for metal to metal?

Adiseal has been shown to be the strongest adhesive in an independent metal to metal adhesive strength test. The adhesive bond on Adiseal broke at 245 psi whereas all other adhesives broke at 224 psi or lower in the metal to metal adhesive bond strength test. Adiseal also provides flexible, waterproof and durable bond.
