Unlike traditional water-based adhesives, cyanoacrylate glue consists of acrylic resins. The main ingredient in cyanoacrylate glue is ethyl-cyanoacrylate, an acrylic monomer that turns into a plastic state when cured.
Cyanoacrylate glue is also different from traditional glues because of its special bonding conditions. This is because cyanoacrylate glue will only bond to a surface in the presence of moisture, which reacts instantly on exposure to air, providing there is even just a small amount of relative humidity in the atmosphere. That said, cyanoacrylate glue will not stick to the surface or form a bond if it is placed on a completely dry surface.
Conversely, if there is any moisture on the surface or in the air, the molecules in the cyanoacrylate glue react with the moisture to form a tight chain between the two surfaces in contact. This reaction will generate heat and happen in an instant, which is different from the principle of traditional glue bonding through the evaporation of the base liquid.
