Epoxy adhesives are a significant part of the class of adhesives called “structural adhesives” or “engineering adhesives”. They can be developed to suit almost any application and can be used as adhesives for wood, metal, glass, stone, and some plastics. You can get a transparent or opaque/colored layer after getting cured.
When you are looking for a sturdy product to give a flawless finish, you can choose either jb weld or gorilla epoxy.
So, which one will be right for you between gorilla epoxy vs jb weld?
Both are quite sturdy to give a flawless finish. The gorilla epoxy dries quickly and gets a transparent color after fully cured. In contrast, the JB weld can withstand hardest environments and has bond strength of 5020 psi.
What Is Gorilla Epoxy?
Gorilla Epoxy adhesive is robust and durable, with superior solvent and water resistance features for household and automotive repairs.
It comes in an easy-to-use syringe that keeps the epoxy resin and hardener separate, making it easy to dispense. This two-part, gap-filling formula bonds aluminum, steel, glass, ceramic, wood, tile, and most plastics. Plus, it dries in a flawless, transparent finish that makes projects look immaculate.
What is JB weld?
JB weld is a high-temperature epoxy adhesive that helps to bond materials together. It is used to create bonding between materials made of any combination of iron, steel, aluminum, wood, ceramic, glass, PVC, and many more.
This one is a two-component epoxy system that was first introduced as a substitute for traditional torch welding. It has a tensile strength of 3960 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550ºF when fully cured. It takes about 15-24 hours to cure completely.
What Are The Differences Between Gorilla Epoxy And Jb Weld?
Before going any further, check out the Gorilla epoxy vs JB weld comparison chart to quickly choose the right one for you –
|Features||Gorilla Epoxy||JB weld|
|Moisture Resistant||Water resistant||waterproof|
|Drying time||less||More than gorilla epoxy|
Application Temperature And Service Temperature:
Gorilla epoxy is suitable for outdoor use. The range for gorilla epoxy is from – 50° to 100° F, and from -10° to 180° F, respectively.
On the contrary, J-B Weld can withstand a constant temperature of 500 °F (260 °C) when fully cured, and the maximum temperature threshold is approximately 600 °F (316 °C) for 10 minutes.
Gorilla Epoxy may work well on PVC sheets but is not recommended for PVC pipes or certain low surface energy plastics like polyethylene (PE) and polypropylene (PP), or certain types of rubber with high oil or plasticizer content.
It should not be used on neoprene, faucet, decking like treks, or timber tech as well. It works on most surfaces, including wood, metal, stone, ceramics. In contrast, J-B Weld will not adhere or bond well to any flexible rubber surface, leather, vinyl, canvas, polypropylene plastic, polyethylene plastic.
Gorilla epoxy is water-resistant but not waterproof. So, it is not recommended for continual water exposure. On the contrary, the jb weld is waterproof.
Gorilla epoxy can be painted with latex paint. J-B Weld can also be drilled, formed, ground, tapped, machined, sanded, and painted.
This is recommended to sand the working surface for both gorilla epoxy and jb weld. This step will not crease the bond strength.
Gorilla epoxy is stainable and can be stained with a water-based stain.
The JB weld can hold more weight for a longer time. And the torque resistance is also great for JB weld.
Gorilla takes less time to get dried than JB weld.
The color of gorilla epoxy after getting cured is clear. J-B Weld Original epoxy dries to a dark grey color. The clear color is often preferred when appearance is an important consideration.
Storage Tips – Store in a cool, dry location. Keep resin and hardener separate. Wipe tip clean with a dry cloth.
Gorilla epoxy is used for filling voids and bonds uneven and vertical surfaces.
The bond strength of gorilla epoxy is around 3300psi. And the bond strength of J B weld is around 5020psi.
Gorilla Epoxy is not recommended for direct or indirect food contact and should not be considered food safe. However, when fully cured, J-B Weld is non-toxic, heat-resistant, and food safe. However, we do not recommend consuming this one as well.
Important Cure Times:
For Gorilla Epoxy
- Set: 5 minutes to apply and position
- Handling: Allow to cure for 30 minutes undisturbed (no weight or handling)
- Final Cure: Allow 24 hours for load-bearing weight.
For J B weld
- Set: Takes 3 to 4 hours
- Final Cure: The mixture will set enough for the glued parts to be handled within 4–6 hours but requires up to 15 hours (at cool temperatures) to fully cure and harden.
JB Weld Vs Gorilla Epoxy – Which One To Choose?
You may need something which dries quickly. Or you are looking for a sturdy adhesive. Again, you may be looking forward to a little more pliable. Some epoxies form a firm bond in only five minutes, and others can take three hours of clamping, 15 hours of drying time, and one to two days until they are fully cured. So, choose according to your needs.
Why choose JB weld:
- For bond strength
- For food safety
- For great waterproof feature
Why choose Gorilla Epoxy:
- For less drying time
- For clear appearance
How much is the shelf life for gorilla epoxy?
The Shelf life for Gorilla Epoxy is a maximum of two years. The epoxy is not activated until the resin and hardener get mixed. So, the shelf life will be much longer if the tip is wiped clean after each use and the cap is securely replaced.
How should I store Gorilla Epoxy?
While closing the cap, you have to notice the notch on the cap and be sure to align that with the notch on the syringe tip. It will ensure the two parts do not accidentally mix.
Why do I need to use clamps?
Clamps ensure the bond sets correctly. When your project is set, clamp and leave undisturbed for 30 minutes.
How do I remove Gorilla Epoxy from my surface?
To clean the surface while the epoxy is still wet/uncured, wipe up as much material as possible and clean any remaining product/residue with Iso propyl alcohol (IPA) or acetone used to manufacturer’s instructions or soap and water. For cured/dried Epoxy, mechanical means such as sanding or scraping are necessary.
How will be the work area?
It is recommended to use these materials in a well-ventilated area.
What is JB Weld made of?
The resin in J-B Weld is bisphenol-A, combined with epichlorohydrin.
So, which one is the winner between Gorilla epoxy vs jb weld, according to you?
Keep in mind the caveats to avoid any mishaps.
You have to clean the surface to have the best result. If the surface preparation is not done properly, it is not realistic to expect the epoxy to stick. And If you maintain the steps properly, the adhesives are incredibly versatile and can be seen in many industries, including electronics, medical devices, aerospace, residential, commercial. Also, these are great instrumental materials for homeowners, contractors, and engineers.
