Article Highlights
- J-B Weld Plastic Bonder is a high-strength, fast-curing structural adhesive syringe with long-lasting results.
- The PlasticWeld is a quick-setting epoxy syringe, a specially formulated epoxy filler system that provides lasting repairs.
- The ClearWeld is an epoxy syringe with an improved formula. It is multipurpose and sets to a hard and permanent bond.
- The Plastic Bonder is the quickest product among these three.
What are the Main Differences?
J-B Weld products are high-quality, perform better, and are durable.
Here, we discuss the J-B Weld products- J-B Weld Plastic Bonder, J-B Weld PlasticWeld, and J-B Weld ClearWeld.
Plastic Bonder is a two-part, quick-setting, high-strength structural adhesive system providing a solid outcome.
PlasticWeld is a multipurpose, two-part epoxy that provides a lasting bond on various plastic surfaces.
ClearWeld is a two-part, quick-setting, multipurpose epoxy that provides a lasting bond on most surfaces. For more information, compare them in detail.
Tensile Strength
The tensile strength of Plastic Bonder is 3770 PSI, which means that one square inch of Plastic Bondee can hold 3770 lbs.
The PlasticWeld has a tensile strength of 3900 PSI, which means one square inch of PlasticWeld has enough strength to hold 3900 lbs. The ClearWeld has the same tensile strength, which is 3900 PSI.
So, the PlasticWeld and ClearWeld are more potent in tensile strength and can deliver better durability than Plastic Bonder.
Set & Cure Time
The Plastic Bonder claims to be a quick-setting product. It can be set within 15 minutes and cured within 30 minutes. The product cures to a hard and permanent bond.
On the other hand, the PlasticWeld sets in 5 minutes and cures in an hour. The ClearWeld is also the same as PlasticWeld. It sets in 5 minutes and takes around 1 hour to cure adequately.
Overall, the Plastic Bonder is the fastest one, as it claims.

Cure Color
The cure color of Plastic Bonder is tan. It dries tan and leaves a slight tint.
The PlasticWeld cures and dries in a translucent yellow color, which is more like an off-white translucent color on the surface.
Another one is J-B Weld ClearWeld. It has an improved formula designed to cure with an evident, transparent bond. It dries clear when used at a thickness of less than 15 mil.
Compatible Materials
The Plastic Bonder can work on several materials, including ceramic, brick, fiberglass, concrete, plastic, PVC, wood, tile, aluminum, carbon, thermoset and carbon fiber composites, thermoplastics and coated metals, and many more.
It is a versatile product, ideal for flexible and rigid surfaces.
The PlasticWeld is compatible with surfaces like metal, glass, tile, rigid plastics, PVC, ABS, most hard plastics, vinyl, fiberglass, ceramic, and most composites.
Lastly, the ClearWeld from J-B Weld is a multipurpose epoxy that works on metal, ceramic, concrete, wood, fiberglass, glass, plastic, PVC, tile, most plastics, and most metals.
Applications
The Plastic Bonder is great for filling gaps, as well as for plastic-to-metal and plastic-to-plastic bonding.
The Plastic Bonder is suitable for automotive trim, filling dents, bumpers, composite panels, interior, & exterior plastic parts, household repairs, crafts, and more.
Another product is PlasticWeld. It is suitable for DIY repairs, construction repairs, and crafting projects.
Furthermore, the ClearWeld from J-B Weld is suitable for automotive, crafts, and DIY repairs.
Using Method
All three have almost similar ways of using the products. They come in syringes and have products in two parts.
To use the Plastic Bonder, first dispense equal parts from the syringe. Then, mix it well and apply it to the parts where you want to fix it.
Leave it to set for 15 minutes. Within 30 minutes, it will be properly cured and ready to be sanded.
The process is the same for PlasticWeld. It is easy to mix. Add a 1:1 ratio of products from the syringe, apply, and let them dry.
For ClearWeld, it also has a 1:1 mixing ratio, needs 5 minutes to set, and cures in 1 hour. Within this time, it bonds to a hard, permanent bond.
Resistance
Plastic Bonder offers excellent resistance to impact, vibration, and shrinkage, a feature it shares with JB Weld ExtremeHeat, which is designed for high-temperature conditions. It is OEM automotive and HD truck-approved, but it is not water-resistant.
Other products don’t have any suitable information about resistance.
Additional Benefits
Talking about additional benefits, you should know that the syringes are resealable. It doesn’t have a waste cap.
Because of its resealable quality, it prevents leaking and prevents air from curing. The products can be used more than once without drying out.
There is also a mixing tray, and the stick with the package makes the mixing process more accessible. This allows you to make multiple uses of these products.
Editor’s Note
According to all the information about the three products, the main thing to notice is that PlasticWeld and ClearWeld are almost similar in terms of tensile strength, setting and curing time, and compatibility with materials.
On the other hand, the Plastic Bonder lacks better surface strength than PlasticWeld and ClearWeld. But it is the quickest one compared to the other two products.
So, in terms of comparison, the J-B Weld Plastic Bonder structural syringe adhesive is the perfect one for those who want a quick repair, and the other two- PlasticWeld and ClearWeld for better strength.
