Tips for Hot Melt Glue Safety


Hot melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive 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 the user pushes through the gun either with a mechanical trigger mechanism on the gun, or with direct finger pressure. 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.

In industrial use, hot melt adhesives provide several advantages over solvent-based adhesives. Volatile organic compounds are reduced or eliminated, and the drying or curing step is eliminated. Hot melt adhesives have long shelf life and usually can be disposed of without special precautions. Some of the disadvantages involve thermal load of the substrate, limiting use to substrates not sensitive to higher temperatures, and loss of bond strength at higher temperatures, up to complete melting of the adhesive.

Although the pistol is very easy to use and highly safe, the melting glue is hot enough to burn skin and cause severe damage. This is why it is important to follow a few precautions while using hot melt glue.

    Wear proper safety gears like gloves, eyewear and full sleeved clothes.
Keep the nozzle at a distance from the skin and electronic or flammable items.
Refrain from working around water or with wet hands.
Keep the gun out of reach of children and pets, especially when it is on or in use as the glue and high temperature can be very dangerous.
Do not forget to turn the gun off after use to prevent it from melting because of the high heat.

It is very important to check the pistol well before the use for any wear and tear to avoid accidents. You can also use water based adhesives for a number of manufacturing purposes like label and packaging, panel lamination etc.
