What Is Panel Bonding Adhesive?
For example, let’s say your mailbox broke and came off the wall- how do you fix that? You use an adhesive to stick it back! So, you could call adhesives the glue for big structural items.
A panel bonding adhesive, on the other hand, is more specific. It is generally made to be used on your vehicle panels in case they need a fix.
They are made up of a variety of substrates that help panels bond and stick to each other. It also gives your panels protection from rust and any corrosion.
However, there are many sub kinds in this sector too. Some are structural adhesives, while others are non-structural. Always follow OEM guidelines to know which product to buy.
Besides being usable on panels, this kind of adhesives can also be used to bond steel, glass, plastic, wood, and other materials.
But make sure you have verified the suitability twice by checking the packaging details.
How to Use Panel Bonding Adhesives?
Every panel bond adhesive we buy will always have an instructional guide. But going through so much information at a time to do simple work may seem tedious.
That’s why we are here to give you a shortcut guide on how to use these products without having to scratch your heads with technical words.
Step 1: Preparation of Panels
Now, this kind of adhesion product generally should be used on outer panels. To begin, make sure you have worn gloves.
Then, clean out your panels thoroughly to make sure there are no contaminants on the body. Most have rust or seam sealers on them that make it hard to identify the welds. You can use a Roloc disc to clean.
Step 2: Preparing the Adhesion
Next, follow the instruction on the packaging to mix the formulas. The mix ratios are usually written on the body of most.
However, some products don’t need any mixing at all and can be used directly. Moving on, install the adhesive to caulk or pneumatic gun (whichever the brand recommends).
Afterward, equalize your cartridge by pushing it out on a towel or piece of cloth. Make sure you have a smooth flow.
Attach your nozzle and start applying the agent on both your host and replacement panels one by one. Put some extra on the replacement panel.
Step 3: Precautions
Always make sure there is no bare metal surface open in the air when joining two parts. This can cause rusting to your panel, and you will cause further damages to the body. Hence, fully cover the part that needs adhesion with the fluid. Then, you can spread it out evenly by using an acid brush.
Moreover, a critical point while dealing with adhesives is their working time. This term relays how much time you have before a mixture hardens.
For example, if the work time is an hour, it means you have to attach your patch panel by that time, or the agent will no longer bond.
Therefore, finish spreading out your mixture before the work time expires. After that, voila! Your panels are ready to join!
Clamp them together very carefully and tightly. Ensure that the stuck parts are not moved from their clamped positions during the cure time.
Moving them is dangerous because the adhesive is starting to turn solid from the liquid during the cure time. In addition, any movement can cause disruption and result in your panels being out of place.
Never pull them apart either because that will create air pockets on the laid-out adhesion.
Step 4: Joining
Lastly, when joining the two parts, you’ll see some liquid squeezing out. Now, that is a good sign as it’ll protect the outer metal surfaces of your panel from any corrosion.
Wipe the squeezed-out mixture while it’s still wet since that’ll leave some amount of agent still there to protect your metal.
And you’re done! Leave the clamped panels to dry through their cure time. Then, the next day, you’ll find two panels looking as if they were always one.

Things to Consider Before Buying Panel Bonding Adhesive
There are a million kinds of adhesives in the market. Each has a specific volume, use, and compatibility.
If you want the perfect kind of adhesive for your panel, you need to keep in mind a certain number of things before buying. Or else, you can easily end up with the wrong kind of product!
Here are some factors you should be mindful of before buying an adhesion product:
There are many kinds of adhesives out there, and each has an ideal use. For example, epoxy adhesives are usually suitable for all sorts of materials starting from wood, metal, plastic, etc.
If you’re using the product just for regular homely use, you should get a two-part adhesive since they don’t require high heat to dry out.
On the other hand, if you don’t have much time in your hands to carefully clamp your objects, you can use a urethane body panel adhesive.
These agents dry out very quickly and don’t require much affection. They are generally waterproof as well, so you can work outdoor with the product.
There is also an epoxy kind called structural adhesives. Again, it would be best if you bought these only when you need something impact-resistant. Also, always use this adhesive only if your panel manufacturer recommends you to do so.
2. Cure time
You will always find a familiar term called “cure time” in every adhesion agent you buy. This term indicates the amount of time needed for your glue to cure (or harden) completely.
After this amount of time, your joined panels will be ready to use. Therefore, if you need your piece as soon as possible, get a product with the least cure time.
3. Work time
Like mentioned before, work time means the amount of time you can mess with the glue AFTER it has been applied to the body.
That can be anything from 5 minutes to an hour. If you know you’d want to spread out your glue to properly clamp the pieces, get a product with a moderate amount of work time.
Even though this trait might sound petty or irrelevant, in reality, it is quite helpful. Imagine you need an adhesion agent only for one-time use.
But you bought a giant pack you could find at the store. Isn’t that a big waste of both your money and the adhesive?
That’s why always buy a product that has a quantity fitting your needs. You could also try purchasing something that has an extended expiry date when unopened.
5. Heat compatibility
Adhesives and heat go hand in hand. Some act well under heat, some don’t. Some bonds can become brittle and hard to work with under immense heat as the mixture dries out.
However, sometimes you can also use this factor as a plus point as many products have an accelerated cure time with heat. That just means that by applying extra heat, you can cure your joints quicker.
