Why does glue get hot?
As most super glues are resin based, the water content in the air causes a chemical reaction that causes the molecules to rapidly heat and fuse before quickly cooling. It is this heating and cooling that helps the glue bond and harden to whatever surface it is applied to.
Why is glue flammable?
Gorilla glue is highly flammable, including the super glue variant. This adhesive contains a chemical called cyanoacrylate, which is known for its flammable properties. When exposed to heat or an open flame, the cyanoacrylate can react and cause the glue to catch fire.
Why does glue smoke?
Heat and occasionally even smoke and fire can be produced when cyanoacrylate adhesives come into contact with natural fibers, particularly cotton and wool. It's recommended not to use cotton or wool gloves when handling the glue, as this can result in severe skin burns. Leather can also have an exothermic reaction.
Is burning glue toxic?
Hot glue fumes can become toxic if they're overheated. Overheating, by at least 30°C-40°C, could cause chemical breakdown in the adhesive, causing organic material would be released – which may be toxic. Any toxic fumes are likely to be in low concentration, and unlikely to cause any serious harm.
