In our daily life, it’s natural to break or damage something because nothing is for permanent use, and repairing these is like a solution. And whether you’re doing a small repair or a big one, it needs to get a perfect product for each different repairing.

While repairing or welding products that have contact with foods, you should be careful which product you are using in welding is harmful or not. And also, you have to check that welding materials are food grade or not. If they contain harmful ingredients or while heating, if they are not waterproof and release toxic chemicals, don’t use them.

Today I will tell you whether JB weld food is safe or if it is FDA approved or not. So, before using JB weld in any product which has contact with foods, read this article and then think whether you should use it or not.

Is JB weld food safe?

If I say this answer in one word, then it is, “No, JB weld is not food safe,” but there are also other sayings. JB weld is non-toxic when it is fully cured. It is water-resistant, acid-resistant. And when hardened, it is petroleum/chemical-resistant. Also, for 10 minutes, the maximum temperature threshold of withstand is approximately 600 °F (316 °C).

And the constant temperature of withstanding is 500 °F (260 °C). So, if you want, you can use it in food contact materials, but of course, this is not entirely safe because it contains BPA, so you shouldn’t use it. For this, we recommend not consuming the product.

Is J-B Weld FDA approved?

JB weld isn’t FDA approved. JB weld contains BPA, though lots of people still consider BPA as a food-safe, the main thing is it is not food-safe. After being cured, JB Weld is pretty much BPA with a bit of iron. “The authorization of Food and Drug Administration (FDA) of the U.S. has ended the use of BPA in infant formula packaging and baby bottles based on not safety and market abandonment. And also, BPA used baby bottles are banned from the Canada and European Union.”

Also, where there is always some heat, BPA can release and can degrade the bond. So, choosing JB weld as a food-safe is not a good idea because the FDA still did not prove JB weld as a food-grade weld.

Can you use J-B Weld in an oven?

Yes, for the microwave oven, you can use JB weld because instead of infrared radiation (heat), the JB weld is exposed to microwave radiation. It has a great temperature range, and after being cured, it is water-resistant, so it is less risky than other BPA-based products.

And if you want to repair the knife or other stuff which isn’t in direct contact with food, then you can use JB Weld; there isn’t any inappropriate or bad news for a bit of use.

Is J-B Weld toxic when heated

When heated, JB weld is toxic, and it can create a bad odor, but after fully cured, it doesn’t provide any odor smell, or it is also non-toxic. If you want to clean the surface of the products which were repaired with JB weld, please don’t use any alcohol there because it can degrade the bond.        

JB weld also resists vibration, shock, and extreme temperature fluctuations.

Other Where can you use JB weld as food safe?

You can use it where food isn’t directly in contact with the part of a product, like a spoon, handle, knife handle, inside the microwave oven, etc.

Final thoughts

In summary, JB weld is not food safe is likely the main answer for this article. Though you can use it, the main thing is you should not use JB weld for consumption. Because in this HBPA and Iron are not great for consumption. Also, getting attached to these is not suitable for health, so it is better not to get in touch with them.

Finally, choose a food-grade epoxy or glue which is not toxic, and FDA approved for your products that have direct contact with food.
