Top 8 Heat-Resistant Glues in 2022
Here are the 8 best glues that withstand heat very well for their cost:
1. Best Overall – J-B Weld High-Heat 500 Degree Epoxy Glue
The J-B Weld High-Heat 500 Degree glue is an epoxy glue that comes in the form of a putty stick and it is one of the best glues when it comes to heat-resistance
The glue’s formula is designed for bonding metal to metal, but it is also effective with other surfaces such as plastic, PVC, wood, concrete, ceramic, tile, and fiberglass.
The bond created on the surface has high tensile strength and will maintain that strength when exposed to temperature fluctuations as it can withstand up to 450 degrees Fahrenheit of continuous heat and up to 500 degrees Fahrenheit of intermittent heat. It’s also completely water-resistant and impact-resistant.
It takes about 1 hour to set, then about 8 hours to dry and cure fully. Once the glue is cured, it can be drilled, painted, or sanded. However, keep in mind that it doesn’t dry clear instead it dries in a machine gray color.
Pros and Cons
Pros
- It creates a durable bond with high tensile strength
- It’s effective with various kinds of surfaces
- It will maintain its strength when the temperature changes
- It’s water-resistant and impact-resistant
- It can withstand continuous and intermittent heat
- It has a short set and cure time
- It can be drilled, painted, or sanded
Cons
- It doesn’t dry clear

All You Need to Know About Heat-Resistant Glue
What Is Heat Resistant Glue?
Heat-resistant glue is any kind of glue that can withstand extremely high temperatures, ranging from 200°F to 500°F, without losing its properties.
It can be used in various applications as they provide a strong durable bond that’s capable of withstanding temperature fluctuations. Some of the areas of applications of heat-resistant glues include heating and cooling systems, automotive industry, furniture construction as well as repair and finishing.
If heat-resistant glue was exposed to a temperature that’s higher than what it can withstand, it will lose its ability to form a bond that’s strong enough for the purpose it’s being used for.
What Kinds of Glue Are Heat Resistant?
There are various kinds of glues with different properties. So, let’s take a closer look at the kinds of glue that can withstand high temperatures:
Epoxy Glue
Epoxy Glue is made from two components, resin, and a hardening fluid, which come in separate containers. The two components need to be mixed before application otherwise the glue will not be effective.
It can create an extremely strong bond with different kinds of surfaces, however, it takes a long time to fully cure. It’s also water-resistant and heat-resistant.
Super Glue
Super Glue is also known as Crazy Glue and it’s made from a chemical compound called cyanoacrylate.
It can form extremely strong bonds with various kinds of surfaces including plastic, metal, glass, and wood. It’s also water-resistant and heat-resistant.
Keep in mind that the surface this glue is applied to needs to have some degree of moisture in order for the glue to be effective.
Gorilla Glue
Gorilla glue is made from a chemical compound called polyurethane.
It can form a long-lasting bond with various kinds of surfaces including plastic rubber, metal, wood, glass, stone, and ceramic. It’s also water-resistant, heat-resistant, and can withstand a significant amount of pressure.
Silicon Glue
Silicon glue provides high bonding strength when applied on various surfaces, however, it can take some time to dry and cure completely.
It’s flexible which allows you to make adjustments or reposition the surfaces. It’s also water-resistant and heat-resistant.
Can You Make Glue Dry Faster Using Heat?
You can make glue dry faster using heat. It’s generally recommended not to expose the glue to excessive amounts of heat for extended periods of time as this can be damaging to the glue and the surface it’s applied on.
If you’re going to dry glue with heat, make sure you’re using a safe source of heat at a temperature that the glue can withstand, otherwise, you might risk overheating the glue.
Here are some of the ways you can safely use heat to make glue dry faster:
- Use a hairdryer – You need to set the hairdryer to low heat and direct its flow over the glued surface. Make sure to hold the hairdryer at about 12 inches away from the surface for only 2 to 3 minutes at a time. Learn more about how to dry glue quickly with a hairdryer here.
- Use an electric heater – You need to set the electric heater to a low temperature then place it at a safe distance away from the glued surface. It’s recommended to close any doors or windows in the room so that the heat will remain contained inside.
- Use an electric blanket – You need to set the electric blanket to low heat and lay it flat on the ground at a safe distance from the glued surface. It’s recommended to use an old electric blanket because it will be difficult to clean if the glue gets on it.
- Using a natural heat source like the sun – You need to place the glued surface outdoors or near an open window during the day. It’s recommended to use this wat when drying large glued surfaces.
You can also learn about making glue dry quickly using your oven here.
What Happens If You Overheat Glue?
Overheating glue means exposing the glue to a temperature that’s higher than what it can withstand for extended periods of time
This will affect the adhesive properties of the glue causing it to fail at forming a strong bond when applied to any surface.
It will also cause the glue to release harmful fumes with various toxic chemicals. If you inhale a large amount of these fumes, you will experience symptoms like headaches, dizziness, and nausea as well as long-term damage to your lungs that could lead to acute respiratory failure.
Safety Precautions You Need to Take When Applying Heat-Resistant Glue
Glues are made from various chemicals that can be dangerous to work with. So, here are some safety precautions you need to when applying glue to avoid causing any harm to your health:
- Make sure to wear old clothing because most kinds of glue can leave permanent stains.
- Make sure to wear protective gloves as various kinds of glue can cause irritation when it comes in contact with skin. It can also be difficult to remove and might stick your fingers together.
- Make sure to wear a safety mask or respirator and work in a properly ventilated room to avoid inhaling large amounts of glue fumes.
- To improve the ventilation in a room, it’s recommended to open all the windows to allow more fresh air. You can also use an air purifier to absorb some of the fumes from the air.
Frequently Asked Questions
Is Glue Water-Resistant?
Most kinds of glues are not fully water-resistant. The bond formed on the surface might be able to withstand contact with water for short periods of time, however, it will likely become weaker or full completely apart if the glued surface is completely submerged in water.
Can You Freeze Glue?
You can freeze glue, however, it’s not recommended because it might damage the chemical structure of the glue making it weaker or completely unusable when it’s unfrozen. This will depend mainly on the kind of glue you’re freezing and its chemical structure as some glues have very low freezing points so they will not be completely damaged.
How Fast Does Glue Dry?
Glue can take about 1 to 20 minutes to dry and up to 24 hours to cure fully before you can use the surface. The speed of the drying process of glue usually depends on factors like the kind of glue you’re using, the kind of surfaces the glue is applied on, the amount of glue applied, and the temperature of the room you’re working in.
How to Properly Apply Glue to A Surface?
To properly apply glue to a surface, you need to make sure that the surface is prepared for bonding by cleaning it from any contaminants that will interfere with the glue. You also need to apply the glue in thin consistent layers and avoid disturbing the surface until the glue is fully dried and cured.
How to Remove Dried Glue From A Surface?
To remove dried glue from a surface, you will first need to soften it. You can do that by applying a strong solvent like rubbing alcohol or acetone on the glued surface or by applying heat using a hairdryer. Once the glue is soft, the bond is formed with the surface will become weaker and you will be able to easily wipe it off the surface.
