Is Super Glue Flammable After It Dries

Super glue, also known as cyanoacrylate adhesive, is a popular adhesive that is widely used for bonding various materials together. It is known for its quick-drying and strong bonding properties, making it a handy tool for DIY projects and repairs.

But have you ever wondered if super glue is flammable after it dries? Let’s delve into this topic and find out!

Is Super Glue Flammable After It Dries? Exposing the Truth


Understanding Super Glue’s Composition

Super glue is composed of cyanoacrylate, which is a type of liquid monomer. When exposed to moisture, cyanoacrylate reacts and polymerizes, transforming into a solid state. This is the process that allows super glue to bond materials together quickly.

However, it is essential to note that although super glue dries quickly, it does not completely lose its flammable properties during the drying process.

Flammability of Super Glue

Super glue is highly flammable, and its flammability remains even after it has dried. The primary reason for this is the presence of residual moisture in the glue. Although the glue may seem fully dry on the surface, the interior of the bond may still contain some moisture.

When exposed to a high heat source, the remaining moisture in the super glue can undergo a rapid evaporation process and cause the glue to release flammable fumes. These fumes can ignite and result in a fire hazard.

Safety Precautions When Handling Super Glue

Given super glue’s flammability, it is crucial to take certain safety precautions when handling and storing it:

  1. Always use super glue in a well-ventilated area to reduce the concentration of fumes.
  2. Keep away from open flames, sparks, and heat sources while using super glue.
  3. Avoid smoking or lighting cigarettes near super glue.
  4. When not in use, ensure the glue cap is tightly sealed to prevent evaporation of moisture.
  5. Store super glue in a cool and dry place, away from direct sunlight or extreme temperatures.

What to Do If a Super Glue Fire Occurs?

In the event of a super glue fire, follow these steps:

  1. Do not attempt to extinguish the fire with water, as water will only spread the flames due to the glue’s hydrophobic nature.
  2. Turn off any nearby heat sources or electrical appliances.
  3. Use a dry chemical fire extinguisher or smother the flames with a fire blanket.
  4. Evacuate the area and call emergency services if the fire becomes uncontrollable.

Frequently Asked Questions On Is Super Glue Flammable After It Dries? Exposing The Truth

Is Super Glue Flammable After It Dries?

Super Glue is not flammable once it’s completely dry. It undergoes a chemical reaction that makes it highly resistant to heat and flames.

Can Super Glue Catch Fire?

Super Glue itself does not easily catch fire, as it is not a highly flammable substance. However, it is advisable to keep it away from open flames or heat sources.

Will Super Glue Burn If Exposed To Fire?

While Super Glue may not ignite or burn in a typical fire, it can degrade and release toxic fumes when exposed to high temperatures. It’s best to avoid subjecting it to extreme heat.

Should I Be Concerned About The Flammability Of Super Glue?

Unless you intentionally expose Super Glue to direct flames or extremely high temperatures, there’s no need for major concern about its flammability. However, always exercise caution when using any adhesive product.


While super glue is an effective adhesive, it is important to remember that it is flammable even after it dries. To ensure safety when handling super glue, follow the necessary precautions and store it properly. If a fire occurs, take immediate action to extinguish it safely.

By being aware of super glue’s flammability and taking the necessary precautions, you can continue to use this versatile adhesive safely and effectively for your projects and repairs.
