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.

Coming to a specific choice here in terms of the number one pick is actually somewhat difficult. The reason for this is because the number one pick for the best high heat glue is going to depend on the specific application you need it for. Let’s break it down a little bit here.
- For instance, if you need a heat resistant, waterproof, non-toxic, and dishwasher safe glue to repair dishes, ceramics, and pottery, it’s Elmer’s China & Glass Cement that you want to go for.
- If you are looking for a heavy duty and super high bond strength heat resistant glue for gluing metal to metal, it’s J-B Weld Steel Reinforced Epoxy you will want to consider.
- If you require an indoor and outdoor, heat resistant, waterproof, and all weather construction adhesive for landscaping, construction, and outdoor repairs, it’s Gorilla Heavy Duty Construction Adhesive that might be right for you.
- When it comes to general heat resistant glue, such as multi-purpose super glue, the overall number one pick is going to be Krazy Glue Maximum Bond, with Loctite GO2 Gel Super Glue being a close runner up.

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
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.
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
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
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
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.

Moreover, this product forms an extremely tough seal that has great impact resistance. Not only does this stuff form a super tight bond, but it also remains flexible once dry, which is a big bonus for many applications.
In terms of usage, keep in mind that this product is ideal for materials including glass, metal, plastics, fiberglass, wood, brick, and stone. As long as the surface is clean, it will adhere and bond just fine. Yes, this product is also 100% waterproof, so it works well for areas that see a lot of humidity and moisture. If you need to make repairs or replace old seals, then this is a great option to consider.
This silicone sealant has a very high bond strength, yet it also remains flexible and impact resistance for many years after curing.
Do keep in mind that this is silicone, so it is also 100% waterproof, thus making it ideal for applications that involve a lot of humidity. What is actually really cool about this product is that it is food contact safe.
We do also happen to like how this product comes in a caulking tube, so you can easily dispense it with a basic caulking gun, and moreover, this also allows for a great deal of accuracy. Beware that this product does take about 24 hours to totally cure, give or take.
Yes, this is a silicone sealant, so it is waterproof once dry, and therefore ideal for use in applications that involve a lot of moisture. The recommended uses for this product include the sealing of valve covers, oil pans, timing covers, water pumps, thermostat housings, transmission pans. Do keep in mind that this is a very small bottle, so it won’t go a long way, but the applicator tip does allow for precise application.
