You may have heard that plastic weld and plastic bonder are different names for the same product. That’s partly true, but there are some differences in how they work and what they’re best used for.
Plastic bonders and plastic welds seem to work in similar ways. They both bond two pieces of plastic together, creating something stronger than the original two pieces combined.
Here’s everything you need to know about plastic bonders vs. plastic welds to make the right choice.
What is Plastic Bonder?
A plastic bonder is a two-part adhesive that creates a strong, permanent bond between two pieces of plastic. It can be used on various plastics, including polyethylene, polypropylene, and PVC.
Plastic bonder sets quickly, so it’s essential to have your pieces lined up before you start applying the adhesive. Unlike many other adhesives, this one works best when there are small spaces in the material being bonded.

What is Plastic Weld?
Plastic weld is a process of joining two pieces of plastic together using heat and pressure. The heat melts the plastic, and the pressure fuses the two pieces. This type of joint is powerful and can be used on various plastics.

Plastic Bonder vs. Plastic Weld
Plastic Weld Defined
Plastic welding is the process of joining two pieces of plastic together and to create a more powerful bond than what would happen if a metal fastener was used.
The welding can be performed by heat, ultrasonic waves, pressure, or friction, depending on the type of plastic being joined.
Plastic welds are often used to create solid and seamless joints in products such as plastic pipes and tanks, medical devices, and consumer electronics.
Plastic Bonder Defined
A plastic bonder is an adhesive explicitly designed for bonding plastic surfaces. It is available in both spray and liquid form and can be used on various plastic surfaces, including polypropylene and polyethylene.
Plastic bonders typically have a shorter cure time than other types of adhesives and can provide a strong, durable bond.
Difference Between Plastic Weld and Plastic Bonder
Plastic weld and plastic bonder differ in their purpose, application method, and cure time. A plastic weld is used to join two pieces of plastic together, while a plastic bonder is used to attach one piece of plastic to another surface.
Plastic weld is applied using heat, ultrasonic waves, pressure, or friction, while plastic bonder is typically sprayed or brushed onto a surface. Plastic weld has a longer cure time than plastic bonder and is generally used for larger projects.
Applications
Plastic weld and plastic bonder both have a variety of applications. Plastic weld is often used to create strong, seamless joints in products such as plastic pipes and tanks, medical devices, and consumer electronics.
A plastic bonder is often used to attach a vehicle’s plastic trim, badge, and other exterior parts. It can also be used to bond together plastic surfaces in the home, such as shower walls and bathtubs.
Material Compatibility
Plastic weld and plastic bonders are compatible with various plastic materials. However, it is essential to check the compatibility of the adhesive with the plastic surface before use.
Plastic weld is typically compatible with polypropylene, polyethylene, and PVC. Plastic bonder generally is compatible with polypropylene, polyethylene, ABS, and polycarbonate.
Cure Time
Plastic weld and plastic bonder have different cure times. Plastic weld has a longer cure time than plastic bonder.
Plastic weld typically cures 1-2 hours, while plastic bonder typically cures in 30 minutes to 1 hour.

What is Plastic Weld used for?
Plastic weld is an adhesive used to join two pieces of plastic together. It can be used on various plastics, including PVC, ABS, and polycarbonate.
When applied correctly, the plastic weld will create a strong bond that will resist heat and chemicals. This makes it ideal for applications where the joint will be exposed to harsh conditions.
How strong is a Plastic Weld?
A plastic weld is a form of welding, and as such, it is a very strong way to join two pieces of plastic together. It can be stronger than the actual plastic itself. That being said, not all plastics can be welded together.
Different plastics have other melting points, so you must ensure that the two pieces of plastic you’re trying to weld are compatible. If they’re not, the weld will be weak and break apart.
Plastic welds are also susceptible to heat and moisture, so they’re not ideal for outdoor use or for applications where the joint will be exposed to extreme conditions.
Can you sand JB Weld Plastic Bonder?
JB Weld Plastic Bonder is a two-part epoxy that can be used to bond plastic, metal, and ceramic. It can also be used to fill in cracks and holes. The mixed adhesive is a cream color and sets in four hours.
JB Weld adhesives are strong, durable, and heat resistant. To create a smooth surface, you can sand the dried glue with a fine-grit sandpaper.
Last Opinion
If you need a strong, permanent bond, go with a plastic weld. If you need a less permanent bond or need to be able to adjust your work after bonding, go with a plastic bonder. And if you’re not sure which adhesive to choose, experiment on some scrap pieces until you find the right fit for your project!
