Is Super Glue Flammable? Expert Answer

Super glue, also known as cyanoacrylate adhesive, has become a household staple for its exceptional bonding properties. However, with great power comes great responsibility, and understanding the potential risks associated with super glue is crucial. One common question that arises is, “Is super glue flammable?” In this article, we will explore the flammability of super glue and provide essential tips on how to handle it safely.

Understanding Super Glue

Super glue is a fast-acting adhesive that forms strong bonds between various materials such as plastic, metal, wood, and ceramics. Its quick-drying nature and ability to create sturdy bonds make it a popular choice for a wide range of applications.

Is Super Glue Flammable?

Yes, super glue is indeed flammable. The chemical composition of super glue includes cyanoacrylate, a highly reactive substance that can catch fire when exposed to heat or an open flame. It’s essential to handle super glue with care to prevent accidents.

How Does Super Glue Catch Fire?

When exposed to heat or an open flame, super glue undergoes a chemical reaction that releases energy in the form of heat and light. This reaction causes the glue to catch fire, making it important to keep it away from sources of heat or flames.

Safety Precautions When Using Super Glue

  1. Ventilation: Always work in a well-ventilated area to disperse any fumes that may be released during the bonding process.
  2. Avoid Heat Sources: Keep super glue away from heat sources such as stoves, candles, or any open flames to prevent accidental ignition.
  3. Use Sparingly: Apply only the necessary amount of glue to avoid excess fumes and potential flammability issues.
  4. Wear Gloves: When working with super glue, consider wearing gloves to prevent skin contact and potential allergic reactions.
  5. Store Properly: Seal the super glue container tightly after use and store it in a cool, dry place away from direct sunlight and heat sources.

Non-Flammable Alternatives

If you’re working on projects involving heat or flames, consider using non-flammable adhesives such as water-based glues or epoxy resins. These alternatives offer strong bonding capabilities without the risk of catching fire.


Is Super Glue Flammable When Dry?

Even when dry, super glue remains flammable. Its composition makes it highly reactive, and it can catch fire if exposed to an open flame or high temperatures.

Why Does Super Glue Catch Fire?

Super glue catches fire due to its chemical composition. When exposed to heat or an open flame, the molecules in the glue break down and react, releasing energy in the form of heat and light, causing it to catch fire.

Is Super Glue an Explosive?

While super glue is flammable, it is not classified as an explosive. Explosives undergo rapid chemical reactions, resulting in a sudden release of energy. Super glue, on the other hand, does not exhibit such characteristics.

Can Super Glue Withstand Heat?

Super glue is heat-resistant to some extent, but it does have its limits. While it can withstand moderate heat, exposing it to high temperatures can cause it to break down and lose its adhesive properties. It’s essential to follow the manufacturer’s guidelines regarding the heat resistance of the specific super glue you’re using.

What Glue Is Not Flammable?

Various types of glues are non-flammable, such as water-based glues, white glue, and certain types of craft glues. These glues do not contain highly reactive compounds like cyanoacrylate, making them safer options, especially for projects involving heat or open flames.

What Glue Is Flammable?

On the flip side, most model glues, rubber cement, and industrial-strength adhesives are flammable. These glues contain volatile solvents and chemicals that can catch fire when exposed to heat or an open flame. It’s crucial to read labels and handle these glues with care to prevent accidents.


While super glue is a versatile and powerful adhesive, it is essential to respect its flammable nature. By understanding its properties and following safety precautions, you can harness the benefits of superglue while minimizing the associated risks. Always prioritize safety when working with any adhesive to ensure a successful and secure bonding experience.
