The main ingredient in Super glue is Cyanoacrylate (C5H5NO2, for you chemistry buffs). Cyanoacrylate is an acrylic resin that cures (forms its strongest bond) almost instantly. The only trigger it requires is the hydroxyl ions in water, which is convenient since virtually any object you might wish to glue will have at least trace amounts of water on its surface. Air also contains water in the form of Cyanoacrylate molecules start linking up when they come into contact with water, and they whip around in chains to form a durable plastic mesh. The glue thickens and hardens until the thrashing molecular strands can no longer move.

Hot melt adhesive (HMA), also known as hot glue, is a form ofthermoplasticadhesive that is commonly supplied in solid cylindrical sticks of various diameters, designed to be melted in an electric hot glue gun. The gun uses a continuous-duty heating element to melt the plastic glue, which may be pushed through the gun by a mechanical trigger mechanism, or directly by the user. The glue squeezed out of the heated nozzle is initially hot enough to burn and even blister skin. The glue is tacky when hot, and solidifies in a few seconds to one minute. Hot melt adhesives can also be applied by dipping or spraying.


The latest hot melt adhesive advance is the PUR adhesive, which is a 100 percent solid, one-component urethane prepolymer that "behaves like a standard hot melt until it reacts with moisture to crosslink or chain extend, forming a new polyurethane polymer." By curing the polymer in this way, PURs have performance characteristics that are more enhanced than those of standard hot melts. It achieves its ultimate strength over the next few days by reacting with moisture in the air and substrates to form a significantly stronger bond than a conventional hot melt.

Hot melt adhesives are popular because of their fast setting speed, relatively low cost (materials and processing), and low environmental impact. Primary hot melt applications are high-speed applications such as packaging, attaching labels and wood veneer, bookbinding, and textiles.
