Glue Gun – HX-155

A hot glue gun is used in conjunction with a hot melt glue rod. Inside the hot glue gun, there is a heating element that serves to melt the hot glue rod. It is used to join materials. [1]

Hot glue gun loaded with hot glue rod. In industrial use, hot glue guns provide several advantages over solvent-based adhesives. Organic compounds that are easily evaporated are reduced or eliminated, and the drying or curing step is eliminated. Hot glue guns have a long lifespan and can usually be disposed of without special precautions. Some of the disadvantages involve the thermal load of the substrate, limiting application to substrates that are insensitive to higher temperatures, and loss of bond strength at higher temperatures until the adhesive melting is complete. This can be reduced by using reactive adhesives that after solidification undergo further curing, for example, with moisture (e.g., reactive urethane and silicone), or cured by ultraviolet radiation. Some hot glue guns may not be resistant to chemical and weather reactions. The hot glue gun does not lose thickness during solidification; Solvent-based adhesives can lose layer thickness by up to 50-70% during drying. [2]
