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 units} heat up to about 195°C and produce a stronger bond. Also available are dual glue guns which feature a switch so that both low and high temperatures can be used for different purposes.
For industrial purposes, there are a comprehensive range of heavy duty glue guns available which are designed and constructed to optimise production efficiency. These range from high output pneumatic glue guns to variable temperature units.
Glue sticks are on the market in several different diameters 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 set 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 commonest 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 switched on a few minutes before being used so that the heating element and adhesive can warm up. As the glue stick increases in temperature 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.
