Purchasing Glue Guns and Hot Melt Adhesives
Glue guns are available in low temperature and high temperature hot-melt versions. Low temperature glue guns heat up to about 120º C and are more applicable where a high temperature is not wanted. High-temperature glue guns} heat up to approximately 195°C and result in a stronger bond. Also on the market are dual glue guns which include a switch so that both low and high temperatures can be utilised for different applications.
For industrial applications, there are a broad range of heavy duty industrial glue guns available which are designed and constructed to optimise production efficiency. These range from high output compressed air industrial glue guns to multi temperature units.
Glue sticks are buyable in various sizes for different types and sizes of glue guns. The commonest size has a diameter of 11mm. Glue sticks are also available in various lengths, from about 10cm upwards. However, the majority of glue guns will accommodate glue sticks of any length. Hot melt and low temperature glue sticks are available for the different types of glue gun. Hot melt adhesives do not contain any solvents or water. They bond when they fall in temperature and this means that they can set quickly.
For industrial applications, different types of glue sticks are available for specialist uses. The most common diameters are 12 and 43mm. For domestic use, there are only a few types of glue sticks that are available. Glue sticks have different open times, which is the time taken to form a bond. This varies from a couple of seconds to a few minutes.
Glue guns need to be turned on a few minutes before they are used so that the heating element and adhesive can warm up. As the glue stick gets hot it melts and then it can be used to bond different materials together. Care should be taken when operating hot glue guns as hot glue can be dangerous.
