Do not confuse plastic bonder and plastic weld for the same thing!
It’s possible that you’ve heard plastic bonder and plastic weld are both the same products. While these are identical to a degree, there are some key distinctions in their ideal applications.
Both of these products combine two pieces of plastic to produce a more substantial object than the actual two pieces put together. To help you choose wisely, here is everything you must know about plastic bonder vs plastic weld.

Plastic Bonder: What Is It & How It Works?
Plastic bonder, a two-part sealant, forms a solid, long-lasting bond between two plastics. It can also be applied to a variety of plastic materials, including PVC, polyethylene, and polypropylene.
Prepare your pieces by aligning up the components, before you apply the adhesive. This is because the plastic bonder sets quickly. This plastic bonder glue functions sufficiently when working with materials having small gaps.
Plastic Weld: What Is It & How It Works?
Plastic welding involves the process of bonding two plastics using heat and coercion. The plastic is melted by heat and pressure is then applied to put the pieces together.
This kind of joinery is durable and suitable for various plastics.
Plastic Bonder vs Plastic Weld
Plastic welding works by binding two fragments of plastic to create a strong and powerful joint. Depending on the type of plastic you are bonding, the process of welding can be carried out using pressure, friction, heat, or ultrasonic waves.
Plastic welds are typically used to make items and devices which require precise joinery.
The Plastic bonder adhesive is exclusively designed to bond plastic materials such as polyethylene and polypropylene. It is available in two forms, spray, and liquid.
Plastic bonders usually cure faster than other adhesives and make up a strong, durable bond.
How Is Plastic Weld Different From Plastic Bond?
The purpose, application, and curing time are all different in the plastic weld and plastic bonders. A plastic weld works as a mode of joinery between two plastic pieces. Whereas, a plastic bonder works as a two-part epoxy, sticking or bonding plastic to another surface for the craft.
Plastic bonder works by spraying or brushing on a surface, while Plastic welding includes the application of heat, pressure, or ultrasonic pressure. A plastic weld takes longer to cure completely than a plastic bond and is mostly used for industrial or large-scale projects.
Plastic welds and plastic bonds have different applications and use. Plastic weld is often the choice for creating strong, precise joints for items such as PVC pipes, medical devices, consumer electronics, and tanks.
A plastic bonder is typically a go-to choice to fix industrial and auto parts, and other exteriors. It is also a good choice for filling gaps in common house fixtures like bathtubs and shower walls.
Both adhesives are compatible with multiple materials. However, it is necessary for the compatibility to be relevant to the surface of the application with the adhesive.
Compatible materials with plastic welds are polypropylene and other materials like PVC. Compatible materials for plastic bonds are polyethylene, ABS, polycarbonate, and polypropylene.
Plastic bonders and plastic welds, both take different times to cure entirely. Plastic welding takes a lot more time than plastic bonders to cure.
The plastic weld can take up to 2 hours to dry. Whereas, plastic bonder usually takes half an hour to 1 hour.
How Durable Are Plastic Welds?
Since a plastic weld is a type of welding, it is a particularly durable method of joining two plastics. It might even be more durable than a piece of plastic. Having said that, not all plastic can be joined together by welding.
To ensure the strongest bond, you need to check the compatibility between the two pieces of plastic. This is because different polymers have different melting points. If the different polymers are not compatible, the weld can turn out weak and break easily.
Plastic welds are also heat and moisture sensitive, making them unsuitable for outdoor use or at a point where the joint is likely to be exposed to harsh weather.
Plastic weld is a product made to join two plastics incredibly well. It is a fast process, so, you will want to be sure of the location before you glue anything together.
Also, because of the strength, the joinery cannot be undone and can create an undying mess in case of any accidents.
It Is Okay To Sand Plastic Bonder?
Plastic bonder is an excellent adhesive for plastic, metal, and ceramic. The epoxy up on mixed turns into an off-white color paste, which takes approximately 4 hours to set. It comes in handy for a lot of purposes like filling cracks and holes.
Plastic bonders can create a heat-resistant and strong bond, which can be sanded when the adhesive dries completely.
FAQs – Plastic Bonder vs Plastic Weld
Will JB Weld plastic bonder work on polyethylene?
JB weld plastic bonder can dry and cure within 15 minutes to 30 minutes. It is a good choice for adhering polyethylene, polypropylene, PVC, ABS, and polyurethane plastics.
Is JB weld plastic bonder waterproof?
Jb weld epoxy is good for repairing, filling, and covering cracks on multiple plastic surfaces. Most plastic welds provide a flexible bond that is both, water-resistant, as well as UV-resistant.
How strong is Plastic Bonder?
A plastic bonder can attain a tensile strength of up to 3770 PSI when it cures completely.
Which Plastic Adhesive Will You Choose Next?
Clearly, there is no winner between plastic bonder vs plastic weld. Both serve different purposes and are used for different kinds of projects.
Each has a different setting and curing time to reach maximum strength. Both are compatible with different materials and can be used to create strong, water-resistant bonds.
Always consider your needs, the nature of your job, and heat exposure on the junction before making your choice. Thank you for reading, we hope this information was helpful.
