Top 8 Best Heat Resistant Glue

Finding regular glue is not hard, and yes, it comes in all types and sizes too. That being said, when it comes to specific applications, you need a specific type of glue. Sure, regular glue might create a decent bond, but many don’t go much further than that.

Depending on the application, one feature you might need out of your glue is that it is heat resistant. However, finding heat resistant glue for specific applications is easier said than done, yet still possible. This is what we are here to help with right now, to help you find the best heat resistant glue on the market at this time.

Before you go out and buy any sort of heat resistant glue, there are some purchasing factors to keep in mind, as well as some tips too.

Types of High Temperature Adhesives

High Temperature Adhesives

Before we get to talking about different types of adhesives that can handle those high degrees, it is worth noting that there are quite a few different options available. Let’s take a look at the various high temperature adhesives, so you know which one to aim for.

Super Glue

Ok, right off the bat, what is important to note here is that super glue can withstand temperatures up to around 330 degrees Fahrenheit, or around 165 degrees Celsius. Now, with that being said, although super glue, technically known as cyanoacrylate glue, cannot be used for applications involving fire and welding.

Most super glues, when they go above that 330 degree mark, will degrade and release what is essentially cyanide gas into the air. So, although you can use this type of adhesive for areas that get a little hot, it cannot handle extreme heat. Super glue also doesn’t have much impact resistance, just something else to keep in mind.

Epoxy – Heat Resistant

Keep in mind that here we are talking about special heat resistant epoxy, which is a special type of epoxy that contains various additives that increase its heat resistance.

Normal epoxy can resist temperatures of around 150 degrees Celsius or 300 degrees Fahrenheit, but the heat resistant stuff can usually handle temperatures of 325 degrees Celsius or 600 degrees Fahrenheit.

What is also worth noting is that most epoxies are 100% waterproof, plus they often have a good deal of impact resistance and flexibility too. Although the bond formed by epoxy is not the strongest in the world, it should be good enough for most applications.

Silicone – Heat Resistant

Silicone - Heat Resistant

When it comes down to it, the number one type of temperature resistant adhesive out there is silicone, particularly high temperature silicone. The fact of the matter is that silicone is one of the most heat resistant materials out there.

Now, what you do need to beware of is that silicone often makes for a better sealant adhesive than an actual glue. Although it can be used as a plain adhesive, the main purpose of it is generally for things like sealing gaskets.

Normal silicone can withstand temperatures of 150 degrees Celsius or 300 degrees Fahrenheit. However, high heat silicone can withstand temperatures of up to 350 degrees Celsius or just over 650 degrees Fahrenheit.

Factors to Consider When Purchasing High Heat Adhesive

Heat resistant silicone

Besides the specific application you plan on using the glue that can withstand heat for, there are also a number of other considerations you will want to keep in mind before making a purchase.

  • Temperature Resistance – Something worth looking into is how high of a temperature the glue in question can withstand once cured. Not all heat resistant glue is the same, with some being more resistant to heat and some less so.
  • Moisture Resistance – Depending on the specific application, you do want to look for glue that is waterproof or water resistant at the very least.
  • Bonding Time – For the most part, the faster the glue dries, the better off you are. The faster glue can dry, the faster you can get back to work.
  • Viscosity & Clamping – Something else to pay attention to is how thick or viscous the glue in question is. Fast bonding and thick glue is ideal for vertical gluing applications and for situations where clamping may not be possible.
  • Curing Time – The curing time of the glue in question is also worth considering. If you are buying heat resistant glue to paint over or sand over, or even for dishware, how long the glue to takes to totally cure is a big deal.
  • Workability – Some heat resistant glues can then be painted over, sanded, or even drilled into once they are cured.
  • Color – Do consider the final color which the glue dries to. For many applications you will want clear drying glue.
  • Impact and Shock Resistance – Of course, good glue of any sort should be impact and shock resistant, which means forming a strong bond that is also flexible.

Safety Tips for Using High Temperature Glue

Resistant glue

Let’s just go over some quick high temp adhesive tips to keep you safe while using it.

  • Always wear gloves, especially if recommended by the product, as many superglue will bond fingers together.
  • Always wear old clothing because most high quality adhesives can and will stain.
  • Some of the more industrial oriented glues will require you to wear a safety mask or respirator, so always keep that in mind.
  • Always use adhesives, glues, and epoxies in well ventilated areas.

Heat Resistant Glue FAQ

Is Gorilla Glue heat resistant?

This all depends on the specific type of Gorilla Glue. There are well over a dozen different types of glue made by this brand name. There are a few which are heat resistant, but most are not overly so.

How much heat can super glue withstand?

Once again, this all depends on the specific product in question. For instance, the industrial strength construction adhesive we reviewed above can withstand up to 550 degrees Fahrenheit, whereas the Elmer’s glass cement is resistant enough to handle the high temperatures of a dishwasher.

Is heat resistant glue dishwasher safe?

There are actually very few superglues and adhesives which are both heat resistant and totally waterproof, which are the two requirements to make glue dishwasher safe. Yes, there are some, such as the Elmer’s glass cement, but they are few and far in between.

The Verdict

Before you make a final choice, the most important consideration is what you need the glue for. If you’re looking to glue dishes together, be sure the glue is heat and water resistant, as well as dishwasher safe too. We really cannot stress enough how important it is to consider the specific application you require the glue fore before making a purchase.
