What is Heat Resistant Glue
Heat-resistant glue is a type of adhesive that can withstand high temperatures. The heat resistance ranges from 200°F to 500°F (93°C – 260 °C). High temperature adhesives are mainly used for automotive repairs and appliance repair as well as metal, plastics, glass, and wood products.
List of Areas of Application for Temperature-Resistant Adhesives:
- Heating and cooling systems
- Automotive industry
- Furniture construction
- repair and finishing
Types Of Heat Resistant Adhesives By Uses
The main types of heat resistant glue are epoxy resin adhesive or polyurethane adhesive for high strength bonds on surfaces like metal; silicone for materials such as glass where the bond may require extra durability but needs more complex preparation; latex for rubber, vinyl and neoprene where flexibility is a must-have as well as excellent resistance to wear over time.
Let’s break it down a little bit here.
Heat Resistant Glue For Glass
Silicone – This type comes in liquid or paste form, both which can be mixed together before applying them to one another gently with a brush. It has excellent adhesion properties and can withstand extreme temperatures up to 4800°F (2500°C). The downside is that this type can take a long time to dry and cure so it’s not recommended when you’re in need of instant results.
BEST HIGH TEMP GLUE FOR GLASS
Rated to withstand up to 500° F (260° C). Seal fireplace inserts, repair solar panels, apply ceramic tiles to your fireplace surround or heat shielding behind your stove, the uses are endless.
Heat Resistant Glue For Metal
Epoxy – These come in liquid form and are often transparent once applied. They can reach higher strengths than most other types available on the market today but they don’t typically soften under heat.
BEST HIGH TEMP GLUE FOR METAL
J-B Weld HighHeat has lap shear strength of 800 PSI at room temperature and 600 PSI at 400oF (204oC) or more. HighHeat is able to withstand continuous heat up to 450oF (232oC) and intermittent heat of 500oF (260oC). HighHeat is 3x stronger at higher temperatures than conventional epoxy puttys and can be tapped and drilled.
Heat Resistant Glue For Plastic
Thermoset – This type of glue, also known as epoxy resin adhesive or polyurethane adhesive, is a chemically crosslinked product which cannot be remelted and reworked. It’s used to bond two pieces together with high strength adhesion that withstands heat up to 540°F (280°C). The main disadvantage of this type of material is its long working time when compared to thermoplastic glues so it’s not recommended for fast production runs.
Heat Resistant Glue For Wood
Pressure sensitive – These types of adhesives come in liquid form and are applied with a brush or roller, then pressed into place to create strong bonds on porous materials at room temperature. They’re also available as foams that can be sprayed onto surfaces for quick drying which makes them good options for projects requiring extensive amounts of it. The downside is that these don’t do well when exposed to high levels of pressure over time so they should only be used where this type of thing won’t happen too often (like puzzles).
Heat Resistant Glue For Fabric And Leather
Hot melt – This material comes in the form of a wax-like product that’s melted and applied with an iron, then sealed to the surface. They’re very popular among hobbyists for creating quick prototypes because it dries in seconds without any need for a vacuum pump or oven. The downside is this doesn’t work well on porous surfaces so it should only be used where these materials won’t come into contact too often (such as when you want something like velcro).
Heat Resistant Glue For Rubber
Latex – This material dries quickly, with an average drying time of 15 minutes or less at room temperature. It has excellent resistance against wear but isn’t as flexible during its setting process which means that it won’t be able to withstand sudden changes in position without cracking; however, once fully hardened, the bond becomes strong enough to resist tearing and deformation due to heat exposure up to 176°F (80°C) for up 24 hours. It also works well on surfaces like rubber, vinyl, and neoprene.
Properties of High-Temperature Adhesives
There are a few different properties to consider when looking for the best high-temperature glue.
- The first is obviously resistance to heat, which can vary from low (140°F) up to very good (500°F).
- Next would be clarity: you want transparent or translucent if possible; otherwise it will turn yellow as it heats up and eventually into an unusable sticky mess.
- Formulation matters too – some types of adhesives won’t dry properly at higher temperatures without adding something like methanol while others will start bubbling out gas before they even reach their boiling point.
- Finally, there’s tackiness: adhesive that stays put once applied requires more tackiness than other kinds so ideally your choice should include one with longevity in mind.

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.
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
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.
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.

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.
