Is JB Weld Food Safe Or Not? [Explained]

is jb weld food safe? Are you confused about whether or not to use JB Weld in the kitchen too? Read this article and find out!

Haven’t we all heard about JB Weld? Deemed as the world’s strongest bond that allows you to be your strongest self.

So the real question is, is jb weld food safe or not?

JB Weld is made up of several ingredients. Some of which can be considered harmful for consumption such as Bisphenol A (BPA). Thus, do not use JB Weld in places where there’s a risk of consuming the product. However, you can use JB weld in all other places to have a stronger bond than steel.

You must be enticed to know how and where to use JB weld properly. Why the wait then?

Hop in!

Is Jb Weld Food Safe?

JB Weld is a high-temperature epoxy adhesive. It is used to hard-bound materials of any combination together. The weld is known to be extremely strong and sometimes provides a bond that is as strong as steel.

JB Weld has numerous benefits. It’s water and acid resistant, and also chemical resistant when hardened. It is also completely non-toxic when fully cured.

JB weld can hold out against a constant temperature of 500°F for 10 minutes. Hence, it can be deemed as microwave and oven safe. But you need to make sure that it is exposed to microwave radiation and not infrared.

However, JB Weld contains BPA (Bisphenol A). Although JB Weld can withhold up to 600°F, there’s the possibility of exposure to BPA. BPA is known to have many harmful effects.

Thus, BPA is not considered food safe. Therefore, it’s best to not use the product where there are possibilities for consumption.

Bisphenol A- Food Safe Or Not?

BPA has been an issue of concern for some time now. Since the 1960s, BPA has been used for packaging and other uses of plastics.

BPA, or Bisphenol A, is a chemical that can be found in hard plastics or epoxy resins. It is known to have several harmful effects.

While BPA generally has its negative side effects, it is known to be worse when consumed.

When packing containing BPA is stored for a long time, the heat may break down the bonds. This will cause BPA to very easily seep out of the containers. Therefore, make its way into the food that we consume.

JB Weld does have a shelf life of about 25 years after opening. This increases the possibility of the BPA seeping out of the container. 

BPA is seen to have harmful results such as infertility, obesity, heart diseases, and type 2 diabetes.

Where to Use and Not Use JB Weld?

Like every other product, JB Weld has its limitations. While it would work perfectly on most objects, there are exceptions.

Some objects would not suit well to JB Weld. They would not work properly even after being cured. Let us look at some of the objects where JB Weld will and will not work.

To Use

JB Weld can be used on surfaces made up of the following matters.

  • Metal
  • Glass
  • Marble
  • PVC
  • Wood
  • Fabric
  • Paper

JB Weld will work perfectly on the above surfaces. Make sure to follow the steps above to properly apply the adhesive.

To Not Use

JB weld will not bond well to the following

  • Leather
  • Canvas
  • Polyethylene Plastic
  • Polypropylene Plastic
  • Vinyl
  • Rubber 

The presence of any alcohol on the surface of the object will also result in the adhesive not bonding properly.

How to Use JB Weld?

JB Weld is one of the most helpful materials for repairing. You must use it properly when applying. Here are some steps you can use when applying JB weld to a product.

Step 1: Prepare the Object

Be sure to remove any dust particles or any oil or grease. If metal, scrape off the rust or debris if any.

As we have seen before, BPA can very easily leak out of the packaging. Make sure to clean any water off of the surface you are going to be applying the resin on.

Detergent can be used for the best results.

Afterward, use sandpaper to roughen the surface to which the weld will be applied. This will ensure the best repair.

Step 2: Always Use Protection

An epoxy resin as strong as JB weld tends to be harmful to the body. Thus, it is important to make sure it does not contact your skin. 

Make sure to wear eye and hand protection when cleaning the items before use. Avoid breathing fumes and use the product in a well-ventilated area.

Adhesives tend to bond skin well. Be careful and make sure you do not get any of it on any of your body parts. If it does get on your skin, wash with soap immediately and remove it as soon as possible.

Step 3: Mix Equal Portions

The product will come in two portions. The resin and the hardener. Mix equal portions of both in ample amounts.

Pick out a disposable piece of plastic and something that can be used as a paddle, such as a matchstick. Put the resin and the hardener on the plastic. Use the paddle to mix them.

Step 4: Work Quickly

The solutions react quickly. Therefore, you have to mix them quickly before the reaction starts.

The heating up of the mixture indicates the start of the chemical reaction. Once it has started the solution will be set up within a few minutes.

Step 5: Let it Set

Secure the pieces that need to be attached. Hold them there firmly and wait for the glue to set.

Once the glue is set, let it rest for the required time and the product will do its job. Do not use the object before it has been properly set.

How Strong is JB Weld?

JB weld forms a very permanent bond once cured. It can be shaped, drilled, sanded, and filed afterward.

The two components of the adhesives chemically react to form an unrelenting bond.

It has a tensile strength of 3960 PSI. Not only that, it can withstand up to 550ºF once fully cured. The weld takes about 15-24 hours after reaction to form a hard bond.

Once hardened, it is said to be water, chemical, and petroleum resistant. It can also resist shock and extreme vibration and temperature.

It is said to be harder than steel.


Is JB Weld Toxic When Heated?

JB weld is non-toxic when cured. However, if it is heated before curing it can create a bad odor which can be toxic. Try not to use any alcohol when cleaning the product. This will degrade the bond that the weld will form.

How Long Does The JB Weld Smell Last?

The adhesive takes about 15-24 hours to cure permanently. The epoxy itself takes about 15- 20 minutes to set after reactions. The odor that forms after the chemical reaction will disappear after the weld sets.

How To Get JB Weld Off Of The Skin?

Wash your hands immediately after you get any of the weld on your skin. If hand cleaners don’t work, use acetone or lacquer thinner. In case of any significant irritation or allergies, consult your doctor immediately.

Summing Up

So, is jb weld food safe? In summary, the main answer from this article is no. JB Weld food is not food safe. The existence of BPA is very harmful to the body if consumed.

Not to say JB weld is not a good product. It is best to use it in places that are safe and do not risk any consumption.
